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

What comparison would best test whether grass reduces erosion?

Please select an answer first.

Correct answer: A

The correct answer is Compare equal bare and grass-covered slopes after the same amount of water flows over them..

  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 controlled comparison can show whether grass changes the amount of soil moved.
  3. Confirm the explanation: The correct choice is Compare equal bare and grass-covered slopes after the same amount of water flows over them..

A controlled comparison can show whether grass changes the amount of soil moved.

2. QuestionMultiple choice

In a fair erosion test, what is a variable?

Please select an answer first.

Correct answer: B

The correct answer is A factor that can be changed or measured in the investigation.

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Variables are conditions that researchers change, measure, or control.
  3. Confirm the explanation: The correct choice is A factor that can be changed or measured in the investigation.

Variables are conditions that researchers change, measure, or control.

3. QuestionMultiple choice

Which observation is evidence that erosion occurred?

Please select an answer first.

Correct answer: C

The correct answer is The amount of soil in the collection tray increased after water flowed over the 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: Soil collected after flowing water shows that material moved from the slope.
  3. Confirm the explanation: The correct choice is The amount of soil in the collection tray increased after water flowed over the slope..

Soil collected after flowing water shows that material moved from the slope.

4. QuestionMultiple choice

Which is a reasonable prediction for a bare slope during heavy rain?

Please select an answer first.

Correct answer: D

The correct answer is More soil will move from the bare slope than from a slope covered with grass..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Bare soil has less protection from runoff than grass-covered soil.
  3. Confirm the explanation: The correct choice is More soil will move from the bare slope than from a slope covered with grass..

Bare soil has less protection from runoff than grass-covered soil.

5. QuestionMultiple choice

What should stay the same when comparing two erosion slopes?

Please select an answer first.

Correct answer: A

The correct answer is The slope angle, soil amount, and amount of 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: Controlled conditions make the effect of the chosen variable easier to identify.
  3. Confirm the explanation: The correct choice is The slope angle, soil amount, and amount of water.

Controlled conditions make the effect of the chosen variable easier to identify.

6. QuestionMultiple choice

What could a data table record in an erosion investigation?

Please select an answer first.

Correct answer: B

The correct answer is The mass of soil collected from each test 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: A measured mass provides numerical evidence about soil movement.
  3. Confirm the explanation: The correct choice is The mass of soil collected from each test slope.

A measured mass provides numerical evidence about soil movement.

7. QuestionMultiple choice

Why should students repeat an erosion trial?

Please select an answer first.

Correct answer: C

The correct answer is Repeated trials can make the evidence more reliable..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Repeated results help show whether a pattern is consistent.
  3. Confirm the explanation: The correct choice is Repeated trials can make the evidence more reliable..

Repeated results help show whether a pattern is consistent.

8. QuestionMultiple choice

Which conclusion is supported if a planted slope loses less soil in every trial?

Please select an answer first.

Correct answer: D

The correct answer is Plant roots and ground cover helped reduce erosion..

  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 repeated comparison supports a protective effect from vegetation.
  3. Confirm the explanation: The correct choice is Plant roots and ground cover helped reduce erosion..

The repeated comparison supports a protective effect from vegetation.

9. QuestionMultiple choice

Which safety practice belongs in a water-and-soil model test?

Please select an answer first.

Correct answer: A

The correct answer is Clean spilled water and keep the work area free of slipping hazards..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Managing spills and tools keeps the investigation safe.
  3. Confirm the explanation: The correct choice is Clean spilled water and keep the work area free of slipping hazards..

Managing spills and tools keeps the investigation safe.

10. QuestionMultiple choice

What is one limitation of a stream-table model?

Please select an answer first.

Correct answer: B

The correct answer is It represents a much smaller and simpler system than a real river..

  1. Identify the process: Decide whether rock is breaking down, sediment is moving, or a force is causing the change.
  2. Use the evidence: Models are useful but do not include every condition found in nature.
  3. Confirm the explanation: The correct choice is It represents a much smaller and simpler system than a real river..

Models are useful but do not include every condition found in nature.
