LEARNING UNIT 1: THE PHYSICAL ENVIRONMENT 1.3 CLASSIFYING THE NATURAL WORLD With the aid of appropriate examples, distinguish between the four subsystems of the natural environment. The four subsystems of the environment are (p1, 547, 548, 550, 551): Lithosphere Earth’s crust and upper part of mantle. Consists of rocks (igneous, metamorphic and sedimentary), soil and sediments. Weathering occurs where the lithosphere is exposed to the atmosphere. This gives rise to the formation of soil. Atmosphere Gaseous layer surrounding earth Extends to a height of approximately 480 km above the earth's surface. Divided into four parts (temperature change with height): troposphere, stratosphere, mesosphere and thermosphere Weather occurs in the troposphere, the lowest part of the atmosphere Responsible for the distribution of climates Biosphere The part of the earth where all organisms live (many types of flora and fauna. The atmosphere, lithosphere and hydrosphere function together to create the environment of the biosphere. Hydrosphere The water at or near the Earth’s surface as liquid, solid or gas. Includes oceans, lakes, rivers, streams, groundwater and water vapour in the atmosphere. Explain what an ecosystem is. In your explanation, you should refer to: Abiotic components (soils, rock type, climatic conditions and water) Biotic components (plant and animal matter) Ecosystems can also be defined as a community of organisms and the abiotic environment they inhabit and interact with (p2, 549). Indicate what a morphoclimatic region is, and what criteria are used to differentiate between various types of regions on a global scale. Describe the characteristics of each of the eight biomes or morphoclimatic regions distinguished on pages 3–8) in Middleton . A morphoclimatic region refers to the relationship between vegetation, climate, soils and animals in a particular area. Aquatic zones are not included in the classification of morphoclimatic regions.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
