Weathering Erosion Deposition

Front

What is weathering?

Back

The process of breaking down rocks and minerals into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

The process by which soil and rock are removed from one location and transported to another by natural forces like wind, water, or ice.

Front

What is deposition?

Back

The laying down of sediment carried by wind, flowing water, the sea, or ice.

Front

How does wind contribute to erosion?

Back

Wind can lift and carry small particles of soil and sand, leading to the erosion of surfaces.

Front

What role does water play in weathering?

Back

Water can dissolve minerals in rocks, freeze and expand in cracks, and transport sediments, contributing to both weathering and erosion.

Front

What is the impact of vegetation on erosion?

Back

Plants help anchor soil in place, reducing erosion by wind and water.

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 rocks through chemical reactions.

Front

What is an example of erosion by ice?

Back

Glaciers moving over land can erode the underlying rock and soil, transporting materials as they advance.

Front

What happens to soil during heavy rainfall?

Back

Heavy rainfall can lead to increased soil erosion as water can wash away topsoil and sediments.

Front

What is the significance of gravity in erosion?

Back

Gravity causes materials to move downhill, leading to processes like landslides and the movement of sediment.
