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 action best reduces erosion on a bare hillside?

Please select an answer first.

Correct answer: A

The correct answer is Plant grass or other vegetation..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Plant roots hold soil and plants slow the movement of runoff.
  3. Confirm the explanation: The correct choice is Plant grass or other vegetation..

Plant roots hold soil and plants slow the movement of runoff.

2. QuestionMultiple choice

How can mulch help prevent erosion?

Please select an answer first.

Correct answer: B

The correct answer is It covers soil and slows the force of falling and moving water..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Mulch protects the surface and reduces the energy of raindrops and runoff.
  3. Confirm the explanation: The correct choice is It covers soil and slows the force of falling and moving water..

Mulch protects the surface and reduces the energy of raindrops and runoff.

3. QuestionMultiple choice

How can terraces reduce erosion on a farm slope?

Please select an answer first.

Correct answer: C

The correct answer is They create steps that slow runoff and hold soil..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Terraces interrupt the slope and slow moving water.
  3. Confirm the explanation: The correct choice is They create steps that slow runoff and hold soil..

Terraces interrupt the slope and slow moving water.

4. QuestionMultiple choice

What can a seawall or planned shore barrier do?

Please select an answer first.

Correct answer: D

The correct answer is It can reduce the direct force of waves on part of the shore..

  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 barrier can protect a section of shore by absorbing or redirecting wave energy.
  3. Confirm the explanation: The correct choice is It can reduce the direct force of waves on part of the shore..

A barrier can protect a section of shore by absorbing or redirecting wave energy.

5. QuestionMultiple choice

What is riprap used for along some stream banks?

Please select an answer first.

Correct answer: A

The correct answer is Large rocks help hold the bank in place..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Riprap is a layer of rocks used to protect soil from moving water.
  3. Confirm the explanation: The correct choice is Large rocks help hold the bank in place..

Riprap is a layer of rocks used to protect soil from moving water.

6. QuestionMultiple choice

How can cover crops protect farmland between growing seasons?

Please select an answer first.

Correct answer: B

The correct answer is Their roots hold soil and their leaves slow wind and rain..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Cover crops reduce exposed soil and help keep it from being carried away.
  3. Confirm the explanation: The correct choice is Their roots hold soil and their leaves slow wind and rain..

Cover crops reduce exposed soil and help keep it from being carried away.

7. QuestionMultiple choice

Why can bare soil be more likely to erode?

Please select an answer first.

Correct answer: C

The correct answer is It has no roots or ground cover to hold it and slow water..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Without vegetation or cover, water and wind can move loose soil more easily.
  3. Confirm the explanation: The correct choice is It has no roots or ground cover to hold it and slow water..

Without vegetation or cover, water and wind can move loose soil more easily.

8. QuestionMultiple choice

How can a rain garden reduce erosion near a building?

Please select an answer first.

Correct answer: D

The correct answer is It collects runoff and lets plants and soil slow the water..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Rain gardens manage runoff and reduce fast-moving water over bare ground.
  3. Confirm the explanation: The correct choice is It collects runoff and lets plants and soil slow the water..

Rain gardens manage runoff and reduce fast-moving water over bare ground.

9. QuestionMultiple choice

What is contour plowing?

Please select an answer first.

Correct answer: A

The correct answer is Plowing across a slope instead of straight up and down 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: Plowing along the contour creates rows that slow water and reduce soil movement.
  3. Confirm the explanation: The correct choice is Plowing across a slope instead of straight up and down it.

Plowing along the contour creates rows that slow water and reduce soil movement.

10. QuestionMultiple choice

Which human action can increase erosion?

Please select an answer first.

Correct answer: B

The correct answer is Removing vegetation from a steep slope.

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Removing roots leaves soil exposed to wind, rain, and runoff.
  3. Confirm the explanation: The correct choice is Removing vegetation from a steep slope.

Removing roots leaves soil exposed to wind, rain, and runoff.

Frequently asked questions about Grade 4 Weathering and Erosion

What is physical weathering?

Physical weathering breaks rock into smaller pieces without changing the minerals into new substances.

What causes erosion?

Water, wind, moving ice, waves, and gravity can move weathered rock, soil, and other sediment.
