A landslide is the movement of rock, earth, or debris down a slope due to gravity.

Front

What is a slump?

Back

A slump is a type of mass movement where a section of land suddenly shifts down a slope, often in a rotational manner.

Front

What is creep in geological terms?

Back

Creep is a slow, gradual movement of soil and rock down a slope.

Front

What is a mudflow?

Back

A mudflow is a rapid flow of water-saturated soil and debris down a slope.

Front

What is deposition in the context of rivers?

Back

Deposition is the process where sediment carried by a river is dropped when the river slows down.

Front

What causes sinkholes to form?

Back

Sinkholes form when underground rock, often limestone, dissolves, creating voids that can collapse.

Front

What is abrasion in geological terms?

Back

Abrasion is the process of wearing away rocks and soil through friction and impact.

Front

How does climate affect erosion?

Back

Climate influences erosion rates; for example, heavy rainfall can increase erosion by water.

Front

What is the role of sediment in river systems?

Back

Sediment is material transported by rivers, which can be deposited to form new landforms.

Front

What factors influence the rate of weathering?

Back

Factors include rock type, climate, and the presence of water.
