Weather 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.

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow and transported to another location.

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

How does freezing water cause weathering of rocks?

Back

Freezing water expands in cracks of rocks, causing them to break apart.

Front

What is a delta?

Back

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

Front

What is chemical weathering?

Back

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

Front

What is physical weathering?

Back

Physical weathering is the mechanical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

How does the slope of a mountain affect erosion?

Back

A higher slope results in more erosion due to the increased gravitational force acting on the soil and water.

Front

What role does the Colorado River play in the Grand Canyon?

Back

The Colorado River eroded the layers of rock in the Grand Canyon over millions of years, shaping its current form.

Front

What is an example of biological weathering?

Back

Biological weathering occurs when plants, such as tree roots, grow into cracks in rocks and break them apart.
