What students learn in AC9S5U02
This unit helps students build a clear, usable understanding of How weathering, erosion, transportation and deposition cause slow or rapid.... The goal is not to memorise one answer pattern. Students should be able to explain the idea, recognise it in a new example and apply it in a short practice or worksheet task.
- Start with the main idea: describe how weathering, erosion, transportation and deposition cause slow or rapid change to Earth’s surface.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- identifying 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 exploring 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
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
Curriculum coverage and elaborations
The content description and elaborations below show the curriculum ideas taught in this unit. Items marked as teaching context support lesson planning but may not appear in the initial eight-question activity.
- Content description: describe how weathering, erosion, transportation and deposition cause slow or rapid change to Earth’s surface
- E1: identifying 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
- E2: exploring 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
- E3: analysing the difference between weathering and erosion and comparing the timescales over which these processes can occur
- E4: modelling the effects of erosion on a simulated landscape and exploring factors that mitigate its effects
- E5: investigating how humans have changed local landscapes and predicting the effect these changes might have on rates of erosion
- E6: considering how First Nations Australians are impacted by the rapid erosion of sand dunes and the resulting effect of saltwater on culturally significant freshwater swamps (teaching context)
- E7: considering the effects of significant rainfall, such as a monsoon, on the transportation and deposition of river sediments in the Asia-Pacific region
How to use this unit
Read the topic guide, use the teacher slide for instruction, then complete the Worksheet, Practice and Test. These three activities use the same eight-question unit bank.

- Describing what is seen without connecting it to a question, pattern or prediction.
- Using everyday words only and missing simple scientific vocabulary.
- Changing more than one thing in an investigation, which makes the comparison unfair.
