Topic 5 - 7 & 10 Questions

Front

What is erosion?

Back

Erosion is the process by which water, ice, wind, or gravity moves weathered particles of rock and soil.

Front

What is chemical weathering?

Back

Chemical weathering is the process that breaks down rock through chemical changes.

Front

What is deposition?

Back

Deposition is the process in which sediment is laid down in new locations.

Front

What is mechanical weathering?

Back

Mechanical weathering is the type of weathering in which rock is physically broken into smaller pieces.

Front

What is desalination?

Back

Desalination is a process that removes salt from sea water to make fresh water.

Front

What are the main agents of erosion?

Back

The main agents of erosion are water, ice, wind, and gravity.

Front

How does chemical weathering differ from mechanical weathering?

Back

Chemical weathering involves chemical changes that break down rocks, while mechanical weathering involves physical breaking of rocks into smaller pieces.

Front

What role does gravity play in erosion?

Back

Gravity causes materials to move downhill, contributing to erosion.

Front

Can you give an example of deposition?

Back

An example of deposition is when a river drops sediment as it slows down and enters a lake.

Front

What is the significance of weathering in the rock cycle?

Back

Weathering breaks down rocks into smaller particles, which can then be transported and deposited, playing a crucial role in the rock cycle.
