Grade 4 Weathering and Erosion Practice Test

Build Grade 4 Science skills with five 10-question practice tests on physical and chemical weathering, erosion by water, wind, ice, and gravity, sediment transport, prevention, and investigations.

Weathering and Erosion Practice Tests

These Grade 4 Science practice tests help students distinguish weathering from erosion and explain how Earth materials change. Students study physical and chemical weathering, water, wind, ice, and gravity, sediment movement, erosion prevention, models, variables, evidence, and conclusions.

Skills covered

  • Distinguishing physical and chemical weathering
  • Explaining frost wedging, roots, abrasion, and chemical reactions
  • Identifying erosion by water, wind, ice, waves, and gravity
  • Recognizing sediment transport and deposition
  • Describing vegetation and engineering methods that reduce erosion
  • Planning investigations and using evidence to support conclusions

How to use these practice tests

Ask whether the Earth material is being broken down in place or transported away. Identify the force involved and look for evidence such as cracks, sediment, runoff, channels, roots, slopes, or layers. For investigations, compare controlled conditions and use measurements to support conclusions.

1. QuestionMultiple choice

Which example shows chemical weathering?

Please select an answer first.

Correct answer: A

The correct answer is Acidic rainwater reacts with and dissolves minerals in limestone..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: A chemical reaction changes or dissolves minerals in the limestone.
  3. Confirm the explanation: The correct choice is Acidic rainwater reacts with and dissolves minerals in limestone..

A chemical reaction changes or dissolves minerals in the limestone.

2. QuestionMultiple choice

Which example shows physical weathering?

Please select an answer first.

Correct answer: B

The correct answer is Water freezes in a crack and breaks the rock apart..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Freezing water breaks the rock without changing its chemical identity.
  3. Confirm the explanation: The correct choice is Water freezes in a crack and breaks the rock apart..

Freezing water breaks the rock without changing its chemical identity.

3. QuestionMultiple choice

Which example shows erosion?

Please select an answer first.

Correct answer: C

The correct answer is Wind carries loose sand away from a dune..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Wind carrying sand is movement of sediment, which is erosion.
  3. Confirm the explanation: The correct choice is Wind carries loose sand away from a dune..

Wind carrying sand is movement of sediment, which is erosion.

4. QuestionMultiple choice

Which example shows deposition?

Please select an answer first.

Correct answer: D

The correct answer is A river drops mud where it enters a lake..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Mud settling where water slows is deposition.
  3. Confirm the explanation: The correct choice is A river drops mud where it enters a lake..

Mud settling where water slows is deposition.

5. QuestionMultiple choice

Which sequence correctly describes a common sediment process?

Please select an answer first.

Correct answer: A

The correct answer is Weathering breaks rock, erosion moves sediment, and deposition settles it..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: The sequence shows breakdown, transport, and settling in the correct order.
  3. Confirm the explanation: The correct choice is Weathering breaks rock, erosion moves sediment, and deposition settles it..

The sequence shows breakdown, transport, and settling in the correct order.

6. QuestionMultiple choice

Which evidence best supports the claim that a river eroded a canyon?

Please select an answer first.

Correct answer: B

The correct answer is The canyon has a channel and rounded sediment that follows the river path..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: A channel and transported rounded sediment are evidence of moving water.
  3. Confirm the explanation: The correct choice is The canyon has a channel and rounded sediment that follows the river path..

A channel and transported rounded sediment are evidence of moving water.

7. QuestionMultiple choice

Which design would best reduce erosion from rain on a school slope?

Please select an answer first.

Correct answer: C

The correct answer is Plant ground cover and create shallow terraces..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Roots hold soil while terraces slow and spread runoff.
  3. Confirm the explanation: The correct choice is Plant ground cover and create shallow terraces..

Roots hold soil while terraces slow and spread runoff.

8. QuestionMultiple choice

Why can weathering and erosion change landforms over long periods?

Please select an answer first.

Correct answer: D

The correct answer is They break down and move Earth materials little by little over time..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Small repeated changes can produce large landform changes over long periods.
  3. Confirm the explanation: The correct choice is They break down and move Earth materials little by little over time..

Small repeated changes can produce large landform changes over long periods.

9. QuestionMultiple choice

Which statement is correct?

Please select an answer first.

Correct answer: A

The correct answer is Weathering can happen where a rock is, while erosion transports the broken material..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Weathering is breakdown, erosion is transport, and deposition is settling.
  3. Confirm the explanation: The correct choice is Weathering can happen where a rock is, while erosion transports the broken material..

Weathering is breakdown, erosion is transport, and deposition is settling.

10. QuestionMultiple choice

Which statement best summarizes weathering and erosion?

Please select an answer first.
