Weathering, Erosion, and Deposition

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 after erosion.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often leading to the formation of new minerals.

Front

What is an example of physical change?

Back

An example of a physical change is ice melting into water.

Front

How does temperature affect chemical reactions?

Back

Greater temperatures allow chemical reactions to occur more quickly.

Front

What is frost wedging?

Back

Frost wedging is a type of mechanical weathering where water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.

Front

What is abrasion?

Back

Abrasion is the process of scraping or wearing away of rocks and soil due to friction and contact with other materials.

Front

What is the rock cycle?

Back

The rock cycle is a continuous process where rocks are formed, broken down, and reformed through geological processes like weathering, erosion, and deposition.
