Weathering

Click here to view the latest Earthlearningidea - 'Weathering - rocks breaking up and breaking down'. In this activity pupils are asked to match pictures and descriptions of weathered rocks with the processes of weathering that formed them.
Weathering occurs all around us, and in all climates. It affects construction materials as well as natural exposures of rocks. Weathering contributes to the concentration of economic resources, such as china clay and bauxite and is very important in the formation of soil. It probably plays a vital role in climate change as well.
