using the earth as a system, what is the function?

Many changes in Earth system functioning directly involve changes in climate. On Earth land, water, air and life interact with one another. These are used for either partial or … and are interrelated. These approaches to flattening the data ar… In particular, it considers interactions and 'feedbacks', through material and energy fluxes, between the Earth's sub-systems' cycles, processes and "spheres"—atmosphere, hydrosphere, cryosphere, geosphere, pedosphere, lithosphere, biosphere, and even the magnetosphere —as well as the impact of human … This allows the protective device to open circuit and thus it is made safe. Of course, biogeochemical cycles have been substantially modified by human activities - a fact that has enormous implications for the understanding and management of environmental issues. This survey will open in a new tab and you can fill it out after your visit to the site. Earth tubes are often a viable and economical alternative or supplement to conventional central heating or air conditioning systems since there are no compressors, chemicals or burners and only blowers are required to move the air. The three main processes of energy transfer at the global scale may be summarised as: It is important to acknowledge that pronounced latitudinal variations occur in these three processes. Electrical point of view ground and earth are same. Students examine Earth as a system (a group of parts working together to perform a function). This, in turn, requires knowledge of its history, which started with the Big Bang. There are also cycles within cycles. Though it is not possible to see deep into the centre of the planet, various scientific tests and predictions such as geological samples and seismic analysis have helped to create a picture of what the Earth (and other planets) look like below the surface. The choice of earthing system can affect the safety and electromagnetic compatibility of the installation. They are the Atmosphere, Geosphere, Biosphere, and Hydrosphere. The earth is a vast, complex system powered by two sources of energy: an internal source (the decay of radioactive elements in the geosphere, which generates geothermal heat) and an external source (the solar radiation received from the Sun); the vast majority of the energy in the earth system comes from the Sun. S denotes that the neutral conductor routed from the source is separate from the protective earthing conductor, which is also routed from the source. Like other environmental systems, biogeochemical cycles involve the flow of substances between stores (also known as reservoirs) in the geosphere, atmosphere, hydrosphere and biosphere. As well as being transferred within environmental systems, energy may also be transformed from one form to another; for instance, a rock fall involves the conversion of potential energy (due to gravity) to kinetic energy (due to movement) and to thermal energy, or heat (due to friction). 2.2.1 The earth system as a set of four overlapping, interacting spheres, AC_FL_RunContent( 'codebase','http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,28,0','width','550','height','780','align','middle','src','media/EarthSpheres','loop','false','quality','high','pluginspage','http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash','play','false','movie','media/EarthSpheres' ); //end AC code. Core, mantle, and crust are divisions based on composition. The key materials that cycle through the major biogeochemical cycles are carbon, oxygen, hydrogen, nitrogen, phosphorous and sulphur - all of which are essential for life. However, the Earth system includes other components and processes, biophysical and human, that are important for its functioning. The energy that drives these processes comes mainly from the Sun and sometimes from energy sources within the Earth. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. Typically then, the biogeochemical cycles involve an inorganic component (the abiotic part of the cycle, including sedimentary and atmospheric phases) and an organic component (comprising plants and animals, both living and dead). For example, a glacier is a relatively unstable system – if the temperature in the atmosphere rises above the melting point of ice, the glacier melts and decreases in ice and the glacier retreats. Geologists have come a long way in terms of the collective knowledge of the Earth and our solar system. This response occurs because the subsystem attempts to maintain its stability, so if one variable changes, other variables may be affected to varying degrees. Earth is the densest planet in the Solar Systemand the largest and most massive of the four rocky planets. Examples of some of these processes include evaporation, erosion, convection currents, transpiration, photosynthesis or weathering. According to the NEC, the purpose of connecting an electrical system to the physical ground (earth) is to limit the voltage imposed by lightning events and contact with higher voltage lines. A system is a collection of interdependent parts enclosed within a defined boundary. The earth system contains several 'great cycles' in which key materials are transported through the environment. The biosphere (life), the lithosphere (land), the hydrosphere (water) and the atmosphere (air). Typically Earth line is connected locally to ground and neutral line goes back to transformer. For example, in a single-wire earth return power distribution system, the earth forms one conductor of the circuit and carries all the load current. For instance, energy may take the form of latent heat which is absorbed or released when substances change state (for example, between the liquid and gaseous phases). Crosscutting Concept 4: Systems and System Models . This paradigm, called "Earth System Science" or simply "Earth System," acknowledges that changes in the solid earth (land - lithosphere or geosphere) result from interactions among the atmosphere (air), hydrosphere (water, including oceans, rivers, ice), biosphere (life) and the lithosphere. The buildup of static electricity within electronic equipment, such as home computers, can create operational problems. The gravitationalinteraction between Earth and the Moon causes tides, stabilizes Earth's orientation on its axis, and gradually slows its rotation. Throughout environmental systems, as energy is transformed from one form to another in performing work, heat is released; that heat is subsequently exported from the system, usually into the atmosphere and then into space. Where groundwater is acknowledged, it is often seen as a static, unchanging component of the water cycle. Based on this way of looking at Earth, they developed the idea of Earth system science. The earth system is itself an integrated system, but it can be subdivided into four main components, sub-systems or spheres: the geosphere, atmosphere, hydrosphere and biosphere. Our atmosphere is a mixture of gases that surround the Earth. Students could engage in the activities Building a water cycle and Constructing an aquifer model, before tracing the many possible paths of an imaginary water molecule within the water cycle in order to identify relevant processes and components. Before starting teaching the water cycle, students need to understand some of the basic scientific ideas underpinning the concept of the Earth system and its four subsystems. Earth system science (ESS) is the application of systems science to the Earth. The four main components of the earth system may be described briefly in the following way. In general, cycles occur in closed systems; at the global scale, many systems may be assumed to be closed because the earth receives negligible quantities of minerals from space (as a result of meteorite impacts) and because only limited quantities of materials can escape the earth's atmosphere. All parts of the Earth System interact . This is a much less important function of the grounding wire, protecting equipment rather than people. An earthing system (UK) or grounding system (US) connects specific parts of an electric power system with the ground, typically the Earth's conductive surface, for safety and functional purposes. At times, students also underestimate the impact of human activities on the water cycle. In contrast, a tree is a relatively stable system that regulates environmental changes due to water shortage, for example, by reducing the size of its leaves’ stomata so it can return to a relative state of equilibrium. TT System. independent of the earth electrodes of the power system. 8.6 Earth Systems Interactions. The four main components of the earth system may be described briefly in the following way. The mantle is hot and represents about 68 percent of Earth’s mass. Yet the total energy content of the earth system remains the same (it is conserved), for energy cannot be created or destroyed. Examples in the Earth system include the rock cycle, the food chain, the carbon cycle, the nitrogen cycle, the water cycle and energy cycles. Such discrepancies are most clearly apparent in the wide variations in surface temperature that exist between the equator and the poles. These components are also systems in their own right and they are tightly interconnected. Ground Wires/Earth Grounding Conductors However each using a different (sometimes) mathematical approach to performing the flattening resulting in different coordinate system grids (discussed below). At a lower level or micro level, it is helpful to think of the Earth system in terms of four central components known as the subsystems – the hydrosphere, geosphere, atmosphere and biosphere. Scientists increasingly view Earth as a dynamic system – a combination of interrelated, interdependent or interacting parts forming a collective whole or entity. In summary - a coordinate reference system (CRS) refers to the way in which spatial data that represent the earth’s surface (which is round / 3 dimensional) are flattened so that you can “Draw” them on a 2-dimensional surface. Water plays a vital role in mediating many of the flows between stores. Curious Minds is a Government initiative jointly led by the Ministry of Business, Innovation and Employment, the Ministry of Education and the Office of the Prime Minister’s Chief Science Advisor. The Earth is a system too. An overall poleward transfer of energy occurs by means of a variety of processes: the transfer of heat by winds and warm air masses; the transfer of latent heat associated with water vapour; the movement of heat in ocean currents; and the returning counter-flows of cooler air and water. Earth Station Tracking System : Tracking is essential when the satellite drift, as seen by an earth station antenna is a significant fraction of an earth station’s antenna beam width. The Earth is made up of four systems, or spheres. The main components of the earth system are interconnected by flows (also known as pathways or fluxes) of energy and materials. The water cycle is the result of a collection of connected processes that distribute water and energy throughout the Earth system in cyclic patterns. Their thinking is often naïve, and few can recognise the complexities involved. An example of energy flow and transformation through an ecosystem is illustrated in 2.2.2. main purpose of earthing system is To provide a low resistance pathway of earthing conductors in order to dissipate the current to the general mass of the earth via deep driven earth rods Earth science (also known as geoscience), is an inclusive term for all sciences related to Earth (geology, meteorology, oceanography, etc). An earth station’s tracking system is required to perform some of the functions such as i)Satellite acquisition ii)Automatic tracking iii)Manual tracking Have students create a spreadsheet function that calculates this value. An extension activity could be to learn more about parts of the water cycle and how it affects the subsystem of system Earth by exploring the article Humans and the water cycle. The earth system is itself an integrated system, but it can be subdivided into four main components, sub-systems or spheres: the geosphere, atmosphere, hydrosphere and biosphere. 1. keeping the Earth's atmosphere, oceans and inhabitants from drifting into space 2. pulling the rain to the rivers and eventually to the sea 3. guiding the development and growth of plants 4. affecting the way that our bones and muscles function Indeed, energy both drives and flows through environmental systems, and energy pathways may be highly complex and difficult to identify. Disciplinary Core Ideas TN-C system: neutral and protective functions are combined in a single conductor throughout the system. 1. Those temperature variations drive the global energy circulation which acts to redistribute heat from the warm to the cold parts of the earth's surface. method of transmitting the instant electricity discharge directly to the ground through low resistance wires or electrical cables These components are also systems in their own right and they are tightly interconnected. These subsystems are interconnected by processes and cycles, which, over time, intermittently store, transform and/or transfer matter and energy throughout the whole Earth system in ways that are governed by the laws of conservation of matter and energy. These subsystems are interconnected by processes and cycles, which, over time, intermittently store, transform and/or transfer matter and energy throughout the whole Earth system in ways that are governed by the laws of conservation of matter and energy. When work is carried out within the earth system, energy is transferred from one body to another, and it may also be converted from one form to another in the process. Such an activity can also highlight the role of time in the cycle and teach students an appreciation that materials move at different rates at any given time. Understanding the universe's birth and its ultimate fate are essential first steps to unveil the mechanisms of how it works. Over time, on-going and repeated change in the distribution and form of water and energy around the globe is caused by processes like evaporation, condensation, freezing, melting, convection currents and infiltration. These four parts are called Spheres. The geosphere- this is the part of the planet composed of rock a… 1.8K views View 1 Upvoter Each response to a change can trigger a string of interconnected responses, which makes the repercussions of any single change in this complex and dynamic Earth system difficult to predict. Earth is largely a closed system, meaning that it exchanges very little matter with its external environment in space, but the same is not true of the systems within the planet — geosphere, hydrosphere, biosphere, and atmosphere — which interact to such a … Key to understanding the complexity of the Earth system is that manipulation in one part of a subsystem can cause effects in other parts of that subsystem and/or the other subsystems, sometimes in ways that are quite unexpected. The internal structure of the Earth is made up of the asthenosphere, the upper mantle, the lower mantle, the outer core and the inner core. Systems can range in complexity, and Earth’s subsystems are all dynamic. How does the universe work? In the example below, the spreadsheet function divides the product of Earth’s scale diameter (B5) and actual distance from the Sun (E5) by Earth’s actual diameter (D5) using =(B5*E5)/D5. On a macro level, the Earth system maintains its existence and functions as a whole through the interactions of its parts, called components. Earth System Science In the phrase "Earth system science (ESS)," the key term is "system." They will also examine the components (spheres) and interactions of these components within the larger Earth system. The earth fault relay is basically a protection device used selectively for earth fault protection. So it can act as a big collecting basin for unwanted voltages and currents what is the function of earthing. Human activity such as agriculture, irrigation, industrial processes, sea transport and sewage disposal can impact on the components and processes of the water cycle in a number of ways – consider the impact of power generation through hydroelectric dams, for example. These structures support the crust of the Earth. Overall, however, these processes of energy transfer maintain a state of equilibrium in the earth system: they remove energy from areas of surplus (in lower latitudes) and transfer it to areas of deficit (in higher latitudes). The most important flows in the earth system are those concerned with the transfer of energy and the cycling of key materials in biogeochemical cycles. It follows that the earth system is only able to continue to function because it is constantly replenished with a sufficient supply of energy (mainly from the sun). These notes discuss the importance of understanding the concept of systems with emphasis on the water cycle, and are aimed specifically for teachers. The Earth system encompasses the climate system. Whilst some variations in these two sources occur, their energy supplies are relatively constant and they power all of the planet's environmental systems. 2.2.3 Carbon cycleClick on the diagram to enlarge, and again to minimise. Key Concepts: Terms in this set (15) Atmosphere. Finally, the core is mostly iron metal. These can be used for both primary and backup protection in an electrical system. the horizontal transfer of sensible heat by the movement of warm air masses, the transfer of latent heat in the form of atmospheric moisture, the horizontal convection of sensible heat by ocean currents. Three of the key biogeochemical cycles are the nitrogen, carbon and sulphur cycles, whose main features are described here. The transfer and transformation of energy are associated with the performance of work; hence the sun performs work in heating the earth by its radiation, and a glacier performs work in moving sediment down-slope using the kinetic energy of its ice, water and rock. The TT distributor system has one point directly earthed, the exposed conductive-parts of the installation being connected to earth electrodes electrically . They can occur at different rates and in different places over time. Earth… Earth System Science is a way of learning about how the Earth works as a system of interacting parts. 4.1.3 . However, since the biogeochemical cycles involve elements that are essential for life, organisms play a vital part in those cycles. The core makes up about 31% of the Earth. IT System Two gases, nitrogen and oxygen, make up most of the atmosphere by volume. It has four major parts all connected and working in harmony to make the planet function properly. the Earth System sustains. "From space we can view the Earth as a whole system, observe the net results of complex interactions, and begin to understand how the planet is changing in response to natural and … The MEN system is designed such that it ensures that when a fault occurs in a way that the active conductor contacted the exposed metal, then the fault current takes the earth conductor as a return path on its way to switchboard. As humans, we are also part of this interaction. The biogeochemical cycles operate at the global scale and involve all of the main components of the earth system; thus materials are transferred continually between the geosphere, atmosphere, hydrosphere and biosphere. An ELCB is a specific type of latching relay that has a structure’s incoming mains power associated through its switching contacts so that the circuit breaker detaches the power in an unsafe condition.The ELCB notices fault currents of human or animal to the earth wire in the connection it guards. N denotes that a low impedance conductor is taken from the earth connection at the source and routed directly to the consumer for the specific purpose of earthing the consuming equipment. Published 3 August 2009, Updated 1 October 2012. Different smaller systems such as like clouds, plants, aquifers and seawater, play a part in the water cycle and influence how water is distributed. Earth grounding systems also help to dump static electrical charges. Research into students’ learning about the water cycle indicates that many students have an incomplete picture of the water cycle and hold many misconceptions. This degree of response also describes how stable or unstable these systems are. The distribution of water is also closely linked to the distribution of other forms of matter, particularly dissolved materials in rivers, lakes and groundwater. Students may only represent the upper part of the water cycle (evaporation, condensation and rainfall) and ignore the ‘less visible’ groundwater, biospheric and environmental components. Energy is transferred within and between environmental systems in three main ways: 2.2.2 Simplified depiction of energy flows and transformations in terrestrial ecosystemsClick on the diagram to enlarge, and again to minimise. The asthenosphere is a semisolid layer of hot rock that's found at the top of the upper mantle. The prime function of an earth electrode is the protection of persons. Environmental science studies the interactions between the physical, chemical, and biological components of the environment, including their effects on all types of organisms. Consequences of this competition emerge in Earth’s climatic processes (global warming), in its biogeochemical cycles (perturbation of the nitrogen cycle), and in the hydrologic cycle (regional changes in quality and quantity of fresh water). The operating system, also known as an “OS,” interfaces with the computer’s hardware and provides services that applications can use. There are many interacting systems that make up the Earth, many of which are dynamic. The energy that drives these processes comes mainly from the Sun and sometimes from energy sources within the Earth. A functional earth connection serves a purpose other than electrical safety, and may carry current as part of normal operation. Within the boundary of the earth is a collection of four interdependent parts called "spheres." Students may also struggle with water chemistry throughout the cycle – ideas about dissolving and purification through percolation and/or evaporation can be problematic. On a bigger scale, the rising temperature in the atmosphere in a region can bring on a cascade of environmental changes to restore equilibrium across the subsystems, such as changes in evaporation and transpiration rates, weather patterns such as winds and precipitationsalinity of water bodies like lakes and seas, and type of species and numbers of organisms. Earth system in terms of four central components known as the subsystems, glacier melts and decreases in ice and the glacier retreats, the rising temperature in the atmosphere in a region can bring on a cascade of environmental changes. A cycle is a collection of connected, on-going processes that circulates a common component throughout a system – such cycles are continuous with no beginning or end. We can assume that earth is not a super conductor but has a zero resistance. In this video lesson, you will see examples of how Earth's spheres interact with each other to form an overall complex and connected system. An operating system is the primary software that manages all the hardware and other software on a computer.
