Erosion and Deposition #2

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is deposition?

Back

Deposition is the process in which sediments, soil, and rocks are added to a landform or land mass.

Front

How does vegetation affect runoff?

Back

Increasing vegetation helps to absorb water, reducing runoff and minimizing erosion.

Front

What are the two main processes by which glaciers cause erosion?

Back

The two main processes are abrasion (scraping) and plucking (lifting away) of rocks.

Front

What is a river delta?

Back

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

Front

What factors increase river erosion?

Back

Increasing the amount and speed of water can significantly increase river erosion.

Front

What is the role of gravity in erosion?

Back

Gravity causes materials to move downhill, contributing to erosion, especially in landslides.

Front

What is the difference between erosion and weathering?

Back

Erosion involves the movement of materials, while weathering is the breaking down of rocks without movement.

Front

What type of erosion creates U-shaped valleys?

Back

Glacial erosion creates U-shaped valleys through the processes of abrasion and plucking.

Front

How do waves contribute to erosion?

Back

Waves can erode coastlines through impact and abrasion, shaping landforms like cliffs and beaches.
