AC9S5U02
Earth and space sciences
describe how weathering, erosion, transportation and deposition cause slow or rapid change to Earth’s surface
Elaborations
- AC9S5U02_E1identifying types of weathering caused by mechanical means such as by wind abrasion, cycles of extreme heat or cold, and frost wedging; and biological means such as by plants and tree roots
- AC9S5U02_E2exploring how erosion can be caused by moving air or moving water and how substances such as surface soil are relocated, and identifying examples of erosion on a local or regional scale
- AC9S5U02_E3analysing the difference between weathering and erosion and comparing the timescales over which these processes can occur
- AC9S5U02_E4modelling the effects of erosion on a simulated landscape and exploring factors that mitigate its effects
- AC9S5U02_E5investigating how humans have changed local landscapes and predicting the effect these changes might have on rates of erosion
- AC9S5U02_E6considering how First Nations Australians are impacted by the rapid erosion of sand dunes and the resulting effect of saltwater on culturally significant freshwater swamps
- AC9S5U02_E7considering the effects of significant rainfall, such as a monsoon, on the transportation and deposition of river sediments in the Asia-Pacific region
