Weathering and Erosion

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces by natural forces such as wind, water, and ice.

Front

What is erosion?

Back

Erosion is the movement of weathered materials from one location to another, often caused by water, wind, 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 occurring in rivers, lakes, and oceans.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition, often caused by ice, frost, or temperature changes.

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 causes a landslide?

Back

A landslide occurs when a large amount of loose dirt and rocks move rapidly down a slope, often triggered by heavy rain, earthquakes, or human activity.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken materials to a new location.

Front

What role do glaciers play in erosion?

Back

Glaciers can erode land by scraping and carrying away rocks and soil as they move, and they can also deposit materials when they melt.

Front

What is sediment?

Back

Sediment is small pieces of rock, soil, and organic material that are transported by wind, water, or ice.

Front

What is a river delta?

Back

A river delta is a landform created by the deposition of sediment at the mouth of a river, where it meets a body of water.
