Unit 2: Weathering, Erosion, Deposition, and Landforms

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces through physical, chemical, or biological means.

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 in which sediments, soil, and rocks are added to a landform or land mass, often occurring when the transporting medium loses energy.

Front

What is an alpine glacier?

Back

An alpine glacier is a type of glacier that forms in mountainous regions and flows down valleys.

Front

What is an alluvial fan?

Back

An alluvial fan is a fan-shaped deposit of sediment that forms where a fast-flowing river slows down as it reaches a flatter area.

Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it deposits sediment as it slows down upon entering a larger body of water.

Front

What is chemical weathering?

Back

Chemical weathering is the process that alters the chemical composition of rocks, often through reactions with water, acids, or gases.

Front

What is physical weathering?

Back

Physical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition, often through mechanical forces.

Front

What are the main agents of erosion?

Back

The main agents of erosion are water, wind, ice, and gravity.

Front

How does vegetation affect erosion?

Back

Vegetation helps to reduce erosion by stabilizing soil with roots and absorbing water, which decreases runoff.
