Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice. There are two types of weathering: mechanical and chemical.
Rocks are weathered by frost action when water fills in a crack and freezes into ice causing the crack to expand. This weathers the rock this thaws the rock and greatly damage â¦ s all of the weathering processes. 9 people found this useful.ny water that gets into cracks or crevices in rocks can cause mechanical weathering when it freezes on a cold morning.
