Weathering_Erosion Flashcard 24/25

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, and transported to another location.

Front

What is deposition?

Back

Deposition is the process in which sediment, soil, and rocks are added to a landform or land mass, often occurring after erosion.

Front

How do plants contribute to weathering?

Back

Plants weather rocks by growing roots into cracks, which can expand and break the rock apart.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown 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 leading to the formation of new minerals.

Front

What role does water play in erosion?

Back

Water can erode land by flowing over it, carrying away soil and sediment, especially during heavy rains or floods.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken materials from one place to another.

Front

What are some examples of erosion agents?

Back

Agents of erosion include water, wind, ice (glaciers), and gravity.

Front

What is the impact of erosion on landscapes?

Back

Erosion can reshape landscapes, create valleys, and lead to the loss of fertile soil.

Front

How does wind cause erosion?

Back

Wind can lift and carry small particles of soil and sand, leading to the erosion of surfaces, especially in dry areas.
