Elaborations

• • Elaboration explaining the diversity of landscapes, such as wetlands, grasslands, forests, cold and hot deserts, and landforms at the national scale; for example, mountains – Himalayan Mountains, Nepal; grasslands – the Steppe, central Asia; forests – Daintree, Australia; cold deserts – Gobi, China
• • Elaboration explaining how tectonics, volcanism, folding, faulting, chemical weathering and physical weathering such as erosion, transportation and deposition shape places; for example, folding – MacDonnell Ranges, Northern Territory, Australia; faulting – Great Sumatran Fault (Semangko Fault), Indonesia; volcanism – Krakatoa, Indonesia
• • Elaboration explaining the effects of rock type on a selected landform at the local scale; such as Fraser Island, Queensland or Twelve Apostles, Victoria; for example, sedimentary – igneous and metamorphic; chemical weathering – oxidation and solution; physical weathering – exfoliation and frost wedging
• • Elaboration explaining the effects of erosion, transportation and deposition of water and wind on a selected landform at the local scale; for example, Fraser Island, Queensland, formed by wind, waves and ocean currents; the Twelve Apostles, Victoria, formed by erosion, tides and ocean currents
