Weathering_Erosion Flashcard 24/25

Front

What is deposition?

Back

The process that drops sediment in a location.

Front

What is mechanical weathering?

Back

The process through which rocks are physically broken into smaller pieces.

Front

What is chemical weathering?

Back

The process through which rocks are broken down through chemical changes.

Front

How does water contribute to mechanical weathering?

Back

Rocks along a riverbed are smoothed from continuously moving water and sediment rubbing against them.

Front

What is an example of mechanical weathering?

Back

A rock sitting on a river for 100 years and being worn down until it is smooth.

Front

How do animals contribute to mechanical weathering?

Back

Animals break up the ground by burrowing.

Front

What is erosion?

Back

The process by which soil and rock are removed from the Earth's surface by wind or water flow.

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.

Front

What role does sediment play in deposition?

Back

Sediment is the material that is dropped and accumulated in a new location during deposition.

Front

What is an example of chemical weathering?

Back

Rocks being worn away from acid in plant roots.
