Weathering

Wears sediment away but leaves weathered material in SITU. There are 3 types of weathering

-Chemical-rocks react with slightly acidic water e.g limestone dissolved by carbonation.

-Biological-Plant and animal activity (e.g burrowing animals or roots widen cracks in rocks) causing the rock to break up.

Mechanical-water seeps into cracks in sediment and freezes, casusing the cracks to expand; repeated freezing and thawing causes the rock to break apart.

Mass movement
