- Recognise that rain can cause a weathering effect by chemically reacting with rock.
- Recognise that types of rock will weather differently due to different chemical composition.
- Explain the observed changes of chemical weathering in terms of the formation of a new substance with different properties.
- Recognise that chemical weathering occurs slowly over long timsecales.
The resources include details of common misconceptions and a summary of the research upon which the resources are based.
