Weathering/Erosion/Deposition

Front

What are the agents of erosion?

Back

Wind, Water, Ice, and Gravity.

Front

What is mechanical weathering?

Back

Mechanical weathering is the process where rocks are physically broken down into smaller pieces without changing their chemical composition.

Front

How does mechanical weathering differ from chemical weathering?

Back

Chemical weathering changes the chemical composition of rocks, while mechanical weathering does not.

Front

What is erosion?

Back

Erosion is the process by which water, ice, wind, or gravity moves weathered rock and soil.

Front

What is a meander?

Back

A meander is a loop-like bend or curve in a river formed by water erosion.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass.

Front

What role does water play in weathering?

Back

Water can cause both mechanical and chemical weathering; it can freeze and expand in cracks, breaking rocks apart, and it can dissolve minerals, changing the rock's composition.

Front

What is chemical weathering?

Back

Chemical weathering is the process that breaks down rocks through chemical reactions, altering their mineral composition.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those weathered materials.

Front

What is an example of mechanical weathering?

Back

An example of mechanical weathering is the freeze-thaw cycle, where water enters cracks in rocks, freezes, expands, and eventually breaks the rock apart.
