Geologic Processes

Front

What is weathering?

Back

The process of breaking down rocks into smaller pieces by physical, chemical, or biological means.

Front

What is erosion?

Back

The process by which soil and rock are removed from one location and transported to another by natural forces such as wind or water.

Front

What is deposition?

Back

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

Front

What are destructive forces?

Back

Forces that break down and destroy landforms, such as erosion and weathering.

Front

What are constructive forces?

Back

Forces that build up landforms, such as volcanic activity and sediment deposition.

Front

What is glacial striation?

Back

Scratches or grooves on bedrock caused by the movement of a glacier.

Front

What is a U-shaped valley?

Back

A valley formed by the erosion of a glacier, characterized by a wide, flat bottom and steep sides.

Front

How do rocks with gaps and cracks weather compared to smooth rocks?

Back

Rocks with gaps and cracks weather more quickly than rocks with smooth surfaces.

Front

What is the role of moving ice in erosion?

Back

Moving ice, such as glaciers, can carve out valleys and shape landscapes through erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken materials.
