Weathering and Erosion

Front

What is weathering?

Back

Weathering is the process that breaks down rocks and minerals into smaller pieces without moving them. It can be caused by water, ice, wind, and temperature changes.

Front

What is erosion?

Back

Erosion is the process that transports weathered particles from one location to another, often caused by water, wind, or ice.

Front

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 energy of the transporting medium decreases.

Front

How does water contribute to weathering?

Back

Water can cause weathering through processes like freeze-thaw cycles, where water seeps into cracks, freezes, expands, and eventually breaks the rock apart.

Front

What role does wind play in erosion?

Back

Wind can erode surfaces by carrying away loose particles, especially in dry areas, leading to the formation of features like sand dunes.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken pieces to new locations.

Front

Can you give an example of mechanical weathering?

Back

An example of mechanical weathering is when rocks are broken apart by the expansion and contraction caused by temperature changes.

Front

What is chemical weathering?

Back

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

Front

What is a common effect of erosion by water?

Back

A common effect of erosion by water is the formation of valleys and canyons as water carves through rock and soil.

Front

How does gravity contribute to erosion?

Back

Gravity causes materials to move downhill, leading to processes like landslides and rockfalls, which are forms of erosion.
