Weathering, Erosion, Deposition and Landforms

Front

What is weathering?

Back

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

Front

What is erosion?

Back

Erosion is the movement of weathered rock and soil from one location to another, often caused 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 landform?

Back

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

Front

What is physical weathering?

Back

Physical weathering is the process of breaking down rocks without changing their chemical composition, often through temperature changes, frost, or pressure.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to reactions with water, acids, or gases.

Front

What is frost wedging?

Back

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

Front

What is oxidation in weathering?

Back

Oxidation is a chemical weathering process where oxygen reacts with minerals, often leading to rusting in iron-rich rocks.

Front

What is a plain?

Back

A plain is a flat, level area of land that is often found at low elevations and can be formed by deposition.

Front

What is a valley?

Back

A valley is a low area of land between hills or mountains, often formed by erosion from rivers or glaciers.
