Weathering, Erosion, Deposition, Soil Review

Front

What is Mechanical Weathering?

Back

Mechanical Weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition. An example is when water freezes in cracks of rocks, causing them to break apart.

What is Chemical Weathering?

Back

Chemical Weathering is the process that breaks down rocks as a result of chemical changes, such as the reaction of minerals with water or acids.

Front

What are some agents of weathering?

Back

Some agents of weathering include water, wind, ice, temperature changes, and plant roots.

Front

How does freezing water cause the weathering of rocks?

Back

Freezing water expands in cracks of rocks, which can lead to the rocks breaking apart.

Front

How many layers does soil have?

Back

Soil typically has three layers: topsoil, subsoil, and bedrock.

Front

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.

Front

What is Deposition?

Back

Deposition is the process where eroded materials are dropped off in a new location, forming new landforms.

Front

What role does temperature play in weathering?

Back

Temperature changes can cause rocks to expand and contract, leading to cracks and eventual breaking of the rocks.

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 from one place to another.

Front

Can plants contribute to weathering?

Back

Yes, plant roots can grow into cracks in rocks, causing them to break apart as the roots expand.
