Weathering, Erosion, Deposition

Front

What is weathering?

Back

Weathering is the process by which rocks are broken down into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process in which wind, water, ice, or gravity moves rock fragments from one location to another.

Front

What is deposition?

Back

Deposition is the process by which sediment is laid down in new locations, often forming features like deltas and beaches.

Front

What causes the greatest amount of erosion on beaches?

Back

Waves cause the greatest amount of erosion on beaches.

Front

What is physical weathering?

Back

Physical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition, often through temperature changes or mechanical forces.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to reactions with water, acids, or gases.

Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, created by the deposition of sediment.

Front

What role does gravity play in erosion?

Back

Gravity causes materials to move downhill, contributing to erosion by transporting rock fragments and soil.

Front

What is sedimentation?

Back

Sedimentation is the process of settling and accumulation of sediment in a new location, often leading to the formation of sedimentary rocks.

Front

How do glaciers contribute to erosion?

Back

Glaciers erode the landscape by scraping and grinding rocks as they move, transporting debris over long distances.
