Table of Contents Water: 3 1.2.3 Compare the state, percentage and distribution of water in the biosphere, lithosphere, hydrosphere and atmosphere. 3 1.2.4 Outline the significance of the different states of water on the Earth in terms of water as: 4 1. A constituent of cells and its role as both a solvent and a raw material in metabolism 4 2. A habitat in which temperature extremes are less than nearby terrestrial habitats 4 3. An agent of weathering of rocks both as liquid and solid 5 4. A natural resource for humans and other organisms 5 5.2.7 Explain why water’s ability to absorb heat is important to aquatic organisms and to life on earth generally. 6 5.2.8 Explain what it is meant by thermal pollution and discuss the implications for life if a body of water is affected by thermal pollution. 7 Energy 8 1.2.1 Outline the role of photosynthesis in transforming light energy to chemical energy and recall the raw materials for this process 8 1.2.2 Outline the role of the production of high energy carbohydrates from carbon dioxide as the important step in the stabilisation of the sun’s energy in a form that can be used by animals as well as plants 9 1.2.3 Identify the photosynthetic origins of the chemical energy in coal, petroleum and natural gas 10 1.3.1 Process and present information from secondary sources on a range of compounds found in either coal, petroleum or natural gas on the location of deposits of the selected fossil fuel in Australia 11 3.3.3 Process and present information from secondary sources and use available evidence to identify safety issues associated with the storage of alkanes. 14 4.2.8 Identify the sources of pollution which accompany the combustion of organic compounds and explain how these can be avoided. 15
