Erosion
Involves the breaking down of rocks and the carrying away of rock particles caused by moving water (rivers), moving ice (glaciers) and moving air (wind)
Deposition
Material that are carried away are eventually dropped in other areas
Mechanical weathering
Breaks into small pieces- frost, sudden temperature changes, plants and animals
Chemical weathering
Rocks to dissolve or decompose by rain
Weathering
is the simple breaking down of rocks that lie exposed to the weather. E.g. Mechanical and chemical
