Weathering, Erosion, & Deposition

Front

What is weathering?

Back

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

What is erosion?

Back

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

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often occurring when the transporting medium loses energy.

Front

How does a fast-moving river cause erosion?

Back

A fast-moving river carries rocks and soil downstream, wearing away the riverbanks and bed, which is a form of erosion.

What role do waves play in deposition?

Back

Waves can deposit sand and other materials on beaches, contributing to the formation of coastal landforms.

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials to a different location.

Front

Can weathering occur without erosion?

Back

Yes, weathering can occur without erosion; rocks can be weathered in place without being transported.

Front

What is an example of mechanical weathering?

Back

An example of mechanical weathering is freeze-thaw action, where water seeps into cracks in rocks, freezes, expands, and eventually breaks the rock apart.

What is chemical weathering?

Back

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

How does rainfall contribute to erosion?

Back

Rainfall can wash away soil from hillsides, leading to erosion as the water carries the soil to lower areas.
