Weathering, Erosion, and Deposition

Front

What is chemical weathering?

Back

Chemical weathering is the process that changes the minerals in rocks, breaking down bonds and altering their chemical composition.

Front

What is physical weathering?

Back

Physical weathering is the process that breaks down rocks into smaller pieces without changing their chemical composition.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often after being transported by erosion.

Front

What is a drumlin?

Back

A drumlin is a streamlined hill formed by glacial ice, typically composed of till, that indicates the direction of glacier movement.

Front

What is the role of glaciers in shaping valleys?

Back

Glaciers erode the landscape as they move, creating U-shaped valleys and other features through the process of erosion.

Front

How does slope affect erosion?

Back

Steeper slopes generally lead to more erosion because gravity pulls materials down more quickly.

Front

What is mass movement?

Back

Mass movement refers to the downward movement of soil and rock due to gravity, which can occur rapidly or slowly.

Front

What are striations?

Back

Striations are scratches or grooves on rock surfaces caused by the movement of glaciers.

Front

What is an erratic?

Back

An erratic is a boulder or rock fragment that has been transported by glacial ice and deposited far from its original location.
