Weathering and Erosion Flashcard

Front

What is weathering?

Back

Weathering is the process where rock is worn away or broken down into smaller and smaller pieces.

Front

What is erosion?

Back

Erosion happens when wind, water, and ice carry away Earth's materials such as sediments or rock.

Front

What is deposition?

Back

Deposition is the process when sediments are carried by water and dropped off to a new location, forming features like deltas.

Front

What are the main agents of weathering and erosion?

Back

The main agents of weathering and erosion are wind, water, ice, and acid rain.

Front

What is the difference between erosion and weathering?

Back

Erosion carries away Earth's materials, while weathering wears down Earth's materials.

Front

What role does wind play in erosion?

Back

Wind can carry away loose particles of soil and rock, contributing to erosion.

Front

How does water contribute to weathering?

Back

Water can dissolve minerals in rocks and cause them to break down.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breaking down 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 due to reactions with water or acids.

Front

What is an example of erosion caused by water?

Back

Rivers can erode the banks and carry sediments downstream.
