Weathering and Erosion

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces by natural forces such as water, ice, and wind.

What is erosion?

Back

Erosion is the process by which weathered rock and soil are moved from one place to another by natural forces like water, wind, or gravity.

Front

What is deposition?

Back

Deposition is the process where eroded materials are dropped off in a new location, forming new landforms.

Front

What causes acid rain?

Back

Acid rain is caused by pollution in the air, which mixes with rainwater and can break down rocks and buildings.

Front

What is a glacier?

Back

A glacier is a large mass of ice that moves slowly over land, causing weathering and erosion of the ground beneath it.

Front

What is mechanical weathering?

Back

Mechanical weathering is the process of breaking 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 due to reactions with water or acids.

Front

What is the role of wind in erosion?

Back

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

Front

How does water contribute to erosion?

Back

Water can flow over land, carrying away soil and rocks, especially during heavy rain or floods.

Front

What is the impact of vegetation on erosion?

Back

Vegetation helps to hold soil in place, reducing erosion by stabilizing the ground with roots.
