Weathering | Erosion | Deposition

Front

What is weathering?

Back

The process of breaking down rocks into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

The movement of sediment and soil from one location to another, often caused by wind, water, or ice.

Front

What is deposition?

Back

The process by which sediment is laid down in new locations, such as sand being dropped on a beach by waves.

Front

What is mechanical weathering?

Back

The physical breakdown of rocks into smaller pieces without changing their chemical composition, often due to temperature changes or freeze-thaw cycles.

Front

What is chemical weathering?

Back

The breakdown of rocks through chemical reactions, often involving water and minerals, leading to changes in the rock's composition.

Front

How do glaciers contribute to erosion?

Back

Glaciers erode the landscape by scraping and carrying away rocks and soil as they move.

Front

What role does gravity play in erosion?

Back

Gravity causes materials like rocks and soil to move downhill, contributing to erosion.

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.

Front

What is an example of deposition?

Back

Sand being deposited on a beach by ocean waves.

Front

How does wind cause erosion?

Back

Wind can lift and carry small particles of soil and sand, moving them from one place to another.
