Investigating the resistance of rocks

Ask your pupils why they think some areas are hilly and others are low-lying. Such differences in relief are often caused by the relative resistance to erosion of the rocks that make up these areas - more resistant rocks usually form higher areas. Try this Earthlearningidea using some of your local rocks and let us know how you get on.
Have you tried the other Earthlearningideas about erosion? There are activities to help teach erosion by ice, water and wind and soil erosion. All these can be found by looking up 'Erosion' in our Keywords Index.
