    2.2 Defining the earth system

    2.2 Defining the earth system

    The main components of the earth system

    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. These components are also systems in their own right and they are tightly interconnected. The four main components of the earth system may be described briefly in the following way.

    The geosphere - this is the part of the planet composed of rock and minerals; it includes the solid crust, the molten mantle and the liquid and solid parts of the earth's core. In many places, the geosphere develops a layer of soil in which nutrients become available to living organisms, and which thus provides an important ecological habitat and the basis of many forms of life. The surface of the geosphere is subject to processes of erosion, weathering and transport, as well as to tectonic forces and volcanic activity, which result in the formation of landforms such as mountains, hills and plateaux.The atmosphere - this is the gaseous layer surrounding the earth and held to its surface by gravity. The atmosphere receives energy from solar radiation which warms the earth's surface and is re-emitted and conducted to the atmosphere. The atmosphere also absorbs water from the earth's surface via the process of evaporation; it then acts to redistribute heat and moisture across the earth's surface. In addition, the atmosphere contains substances that are essential for life, including carbon, nitrogen, oxygen and hydrogen.The hydrosphere - this consists of those parts of the earth system composed of water in its liquid, gaseous (vapour) and solid (ice) phases. The hydrosphere includes: the earth's oceans and seas; its ice sheets, sea ice and glaciers; its lakes, rivers and streams; its atmospheric moisture and ice crystals; and its areas of permafrost. The hydrosphere includes both saltwater and freshwater systems, and it also includes the moisture found in the soil (soil water) and within rocks (groundwater). Water is essential for the existence and maintenance of life on earth. In some classifications, the hydrosphere is sub-divided into the fluid water systems and the cryosphere (the ice systems).The biosphere - this contains all living organisms and it is intimately related to the other three spheres: most living organisms require gases from the atmosphere, water from the hydrosphere and nutrients and minerals from the geosphere. Living organisms also require a medium for life, and are adapted to inhabit one or more of the other three spheres. However, much of the biosphere is contained within a shallow surface layer encompassing the lower part of the atmosphere, the surface of the geosphere and approximately the upper 100 metres of the ocean. Humans are part of the biosphere, although they are increasingly responsible for the creation of systems that may be largely artificial (such as cities).2.2.1 The earth system as a set of four overlapping, interacting spheres

    The main components of the earth system are interconnected by flows (also known as pathways or fluxes) of energy and materials. 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.

    Energy flows

    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. Whilst some variations in these two sources occur, their energy supplies are relatively constant and they power all of the planet's environmental systems. Indeed, energy both drives and flows through environmental systems, and energy pathways may be highly complex and difficult to identify. 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). An example of energy flow and transformation through an ecosystem is illustrated in 2.2.2. Energy is transferred within and between environmental systems in three main ways:

    radiation - this is the process by which energy is transmitted through space, typically in the form of electromagnetic wavesconvection - this is the physical movement of fluids (such as water or air) that contain energy in the form of heat; convection does not occur in solidsconduction - this is the transfer of energy in the form of heat through the substance of a medium (from molecule to molecule)2.2.2 Simplified depiction of energy flows and transformations in terrestrial ecosystems

    Source: Smithson (2008) p. 41

    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). 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. 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. 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. Yet the total energy content of the earth system remains the same (it is conserved), for energy cannot be created or destroyed. 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).
