Front

What is mechanical weathering?

Back

Process through which rocks are physically broken into smaller pieces.

Front

What is chemical weathering?

Back

This type of weathering occurs when rocks weaken and break down due to chemical changes in the composition of the rock.

Front

What is weathering?

Back

The process that breaks down rocks and other materials on Earth's surface.

Front

What is erosion?

Back

The process by which soil and rock are removed from the Earth's surface by wind or water.

Front

What is the main cause of mechanical weathering?

Back

Mechanical weathering is caused by physical forces such as temperature changes, freeze-thaw cycles, and plant growth.

Front

What is acid rain?

Back

Rain that has been made acidic by pollutants in the atmosphere, which can lead to chemical weathering.

Front

How does water contribute to weathering?

Back

Water can freeze in cracks of rocks, expand, and cause the rocks to break apart.

Front

What role does temperature play in weathering?

Back

Temperature changes can cause rocks to expand and contract, leading to mechanical weathering.

Front

What is the difference between mechanical and chemical weathering?

Back

Mechanical weathering physically breaks rocks apart, while chemical weathering changes the chemical composition of rocks.

Front

What is an example of mechanical weathering?

Back

An example of mechanical weathering is the breaking of rocks due to freeze-thaw cycles.
