Chapter 8 - Erosion and Deposition

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

Front

What is groundwater deposition?

Back

Groundwater deposition occurs when minerals dissolved in water are deposited as the water evaporates or cools, forming features like stalactites and stalagmites.

Front

What causes the formation of dunes?

Back

Dunes are formed by the movement of sand caused by wind.

Front

Where do rockfalls and rock slides commonly occur?

Back

Rockfalls and rock slides commonly occur in areas with steep cliffs.

Front

What is chemical weathering?

Back

Chemical weathering is the process that breaks down rocks through chemical reactions, such as water dissolving minerals out of rock.

Front

What is physical weathering?

Back

Physical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition, such as ice breaking rocks.

Front

What is a landform?

Back

A landform is a natural feature of the Earth's surface, such as mountains, valleys, plateaus, and hills.

Front

What is the role of rivers in erosion?

Back

Rivers erode the land by carrying away soil and rock, shaping the landscape over time.

Front

What is the difference between erosion and weathering?

Back

Erosion involves the movement of soil and rock, while weathering is the process of breaking down rocks without movement.
