FLASHCARD (No Grade) 8ESS3 Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the breaking down of rocks and other materials on the Earth's surface through physical and chemical processes.

Front

What is erosion?

Back

Erosion is the process by which rock and soil are moved from one place to another.

Front

What is deposition?

Back

Deposition is the process where materials are laid down or deposited in a new location after being transported by erosion.

Front

What factors influence the rate of weathering?

Back

Factors include climate, type of rock, presence of soil, and vegetation.

Front

What is the difference between mechanical and chemical weathering?

Back

Mechanical weathering physically breaks rocks into smaller pieces without changing their chemical composition, while chemical weathering alters the minerals in the rocks.

Front

How do glaciers contribute to erosion?

Back

Glaciers erode the landscape by scraping and grinding rocks as they move, transporting debris with them.

Front

What are the signs of erosion in a landscape?

Back

Signs include exposed roots, undercut banks, and sediment deposits in water bodies.

Front

What role does vegetation play in erosion?

Back

Vegetation helps to anchor soil in place, reducing the likelihood of erosion.

Front

How can human activities impact erosion?

Back

Human activities like deforestation, construction, and agriculture can increase erosion by removing vegetation and disturbing soil.

Front

What is the significance of sedimentary rocks in understanding erosion and deposition?

Back

Sedimentary rocks often form from deposited materials, providing evidence of past environments and processes of erosion and deposition.
