Mass Movement & Rivers

Front

What is mass movement?

Back

Mass movement refers to the large-scale movement of soil and rock down a slope due to gravity. It includes processes like landslides, mudflows, and creep.

Front

What factors influence erosion in a stream?

Back

Factors influencing erosion in a stream include water discharge, stream gradient, and the type of materials in the streambed.

Front

What happens to sediment during deposition?

Back

During deposition, sediment settles out of the transporting medium (like water) and accumulates in a new location.

Front

What is a meander in a river?

Back

A meander is a curve or bend in a river, formed by the erosion of the outer bank and deposition on the inner bank.

Front

Where does erosion typically occur in a meander?

Back

Erosion typically occurs on the outside of a meander where the water flows faster.

Front

Where does deposition typically occur in a meander?

Back

Deposition typically occurs on the inside of a meander where the water flows slower.

Front

What is a delta?

Back

A delta is a landform created at the mouth of a river where it meets a body of water, formed by the deposition of sediment carried by the river.

Front

What role does water play in sediment transport?

Back

Water acts as a transporting medium that carries sediments downstream, influencing erosion and deposition.

Front

What is the impact of increased discharge on a stream?

Back

Increased discharge can lead to higher rates of erosion as the stream has more energy to transport sediment.

Front

What is the difference between erosion and weathering?

Back

Erosion is the process of moving soil and rock from one location to another, while weathering is the breakdown of rocks into smaller pieces without movement.
