Weathering and Mass wasting
Weathering is the process of breaking down rocks into smaller pieces. It can be physical
or chemical. Physical weathering occurs when rocks are broken down into smaller pieces
without changing their chemical composition. Chemical weathering occurs when rocks
are broken down by chemical reactions that change their composition.
Mass wasting is the movement of rock and soil down a slope due to gravity. It can be
caused by many factors such as earthquakes, volcanic eruptions, and heavy rainfall.
Weathering and mass wasting are closely related. Weathering breaks down rocks into
smaller pieces, which can then be transported by mass wasting. Mass wasting can also
expose new rock surfaces to weathering.
