Weathering and Erosion Quiz

What is the term used to describe the process of breaking down rock on Earth’s surface?

• Sedimentation
• Erosion
• Weathering
• Metamorphism

What is the term used to describe the type of weathering in which rock is physically broken into smaller pieces?

• Chemical weathering
• Biological weathering
• Mechanical weathering
• Erosion

What is chemical weathering?

• Chemical weathering is the breakdown of rocks through chemical reactions.
• Chemical weathering is the process of rocks melting due to high temperatures.
• Chemical weathering involves the erosion of rocks by mechanical forces.
• Chemical weathering is the physical breakdown of rocks by wind and water.

How does abrasion break down rock on Earth’s surface?

• Abrasion has no effect on rock formation.
• Abrasion breaks down rock by wearing it away as particles of rock rub past each other.

• Abrasion causes rocks to melt due to heat.
• Abrasion forms new rocks through chemical reactions.

Explain the process of root wedging.

• Root wedging is the process of plant roots growing into rock cracks, exerting pressure, and causing the rock to fracture.
• Roots grow in soil, not in rock cracks.
• Roots absorb water from rocks, preventing erosion.
• Roots create soil by breaking down rocks into nutrients.

How does the composition of a rock affect its rate of weathering?

• Rocks with higher density weather faster than lighter rocks.
• All rocks weather at the same rate regardless of composition.
• Rocks with more color variations weather slower than uniform rocks.
• A rock's composition determines how quickly it wears away. Rocks with softer minerals weather faster than those with harder compositions.

Explain how the climate in a particular region can affect the rate in which rocks weather.

• Climate has no effect on rock weathering rates.
• Rocks weather faster in colder climates due to less moisture.
• Biological activity is irrelevant to the weathering process.
• Freezing, extreme heat, and rainfall amounts can all affect the rate of weathering.
