Question 1

What is the primary difference between physical weathering and chemical weathering?

Accepted Answer

Physical weathering breaks rocks into smaller pieces without changing their composition.

Answer

Physical weathering can only occur in water.

Answer

Chemical weathering happens at a faster rate than physical weathering.

Answer

Chemical weathering changes the chemical composition of rocks only.

Question 2

What role do plants play in physical weathering?

Accepted Answer

Plants can grow into cracks in rocks and pry them apart.

Answer

Plants primarily cause chemical weathering.

Answer

Plants do not affect weathering.

Answer

Plants protect rocks from weathering.

Question 3

What is the process called when weathered material is moved from one location to another?

Accepted Answer

Erosion

Answer

Weathering

Answer

Sedimentation

Answer

Deposition

Question 4

How does chemical weathering primarily occur?

Accepted Answer

Through reactions between rocks and chemicals in air and water.

Answer

By physically breaking rocks into smaller pieces.

Answer

By the impact of animals digging in the soil.

Answer

Through the movement of ice and snow over rocks.

Question 5

What is a common result of erosion by wind?

Accepted Answer

The formation of sand dunes.

Answer

The breaking of rocks into smaller pieces.

Answer

The creation of chemical changes in rocks.

Answer

The melting of glaciers.

Question 6

What do glaciers do as they move across the Earth's surface?

Accepted Answer

They erode and deposit sediment.

Answer

They form rocks and minerals instantly.

Answer

They only weather rocks chemically without moving them.

Answer

They only melt and do not affect the landscape.

Question 7

What is uniformitarianism?

Accepted Answer

The principle that geologic processes occurring today are similar to those that occurred in the past.

Answer

The idea that all geological changes happen suddenly.

Answer

A method of measuring the age of rocks.

Answer

A theory that Earth is only a few thousand years old.

Question 10

How can animals contribute to physical weathering?

Accepted Answer

By burrowing in the soil and breaking down rocks.

Answer

By transporting sediment to new locations.

Answer

By preventing rocks from weathering.

Answer
