Grade 4 Earth Processes Practice Test

Build Grade 4 Science skills with five 10-question practice tests on weathering, erosion, deposition, sediment, water, wind, ice, landforms, models, and erosion prevention.

Earth Processes Practice Tests

These Grade 4 Science practice tests help students explain how Earth materials change and move. Students identify weathering, erosion, deposition, sediment, the effects of water, wind, ice, and gravity, landform changes, scientific models, and ways to reduce erosion.

Skills covered

  • Distinguishing weathering, erosion, and deposition
  • Explaining how water, wind, ice, and gravity move Earth materials
  • Connecting erosion and deposition to valleys, deltas, beaches, dunes, and floodplains
  • Using observations and models to investigate Earth processes
  • Identifying variables, evidence, predictions, and conclusions
  • Describing ways plants and engineering designs can reduce erosion

How to use these practice tests

First decide whether Earth material is being broken down, moved, or dropped. Then identify the force involved and look for evidence such as sediment, runoff, channels, slopes, plants, or changing landforms. Remember that many Earth processes happen slowly over time.

1. QuestionMultiple choice

What could a stream-table model help students investigate?

Please select an answer first.

Correct answer: A

The correct answer is How moving water changes the shape of sediment and land..

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: A stream-table model can represent erosion, transport, and deposition by water.
  3. Confirm the process: The correct choice is How moving water changes the shape of sediment and land..

A stream-table model can represent erosion, transport, and deposition by water.

2. QuestionMultiple choice

How could a student fairly test how water speed affects erosion in a model?

Please select an answer first.

Correct answer: B

The correct answer is Use the same soil and slope while changing only the water speed..

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: Keeping other conditions the same helps show the effect of water speed.
  3. Confirm the process: The correct choice is Use the same soil and slope while changing only the water speed..

Keeping other conditions the same helps show the effect of water speed.

3. QuestionMultiple choice

Which observation is evidence of deposition in a stream model?

Please select an answer first.

Correct answer: C

The correct answer is A layer of sediment collects where the water slows..

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: Sediment settling in a slower area is direct evidence of deposition.
  3. Confirm the process: The correct choice is A layer of sediment collects where the water slows..

Sediment settling in a slower area is direct evidence of deposition.

4. QuestionMultiple choice

What is a prediction in an Earth-process investigation?

Please select an answer first.

Correct answer: D

The correct answer is A statement about what the student expects to happen..

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: A prediction is an expected result that can be tested.
  3. Confirm the process: The correct choice is A statement about what the student expects to happen..

A prediction is an expected result that can be tested.

5. QuestionMultiple choice

What should students do before and after running water over a model slope?

Please select an answer first.

Correct answer: A

The correct answer is Observe and record the slope shape before and after the water flows..

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: Comparing before-and-after observations provides evidence of change.
  3. Confirm the process: The correct choice is Observe and record the slope shape before and after the water flows..

Comparing before-and-after observations provides evidence of change.

6. QuestionMultiple choice

Which result could show that faster water carries larger sediment pieces?

Please select an answer first.

Correct answer: B

The correct answer is The fast-water trial moves pebbles while the slow-water trial moves only sand..

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: The comparison connects water speed with the size of material transported.
  3. Confirm the process: The correct choice is The fast-water trial moves pebbles while the slow-water trial moves only sand..

The comparison connects water speed with the size of material transported.

7. QuestionMultiple choice

Which safety rule is important during a stream-table investigation?

Please select an answer first.

Correct answer: C

The correct answer is Keep water away from electrical equipment and clean spills..

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: Water and electricity can be dangerous, so spills and equipment must be managed safely.
  3. Confirm the process: The correct choice is Keep water away from electrical equipment and clean spills..

Water and electricity can be dangerous, so spills and equipment must be managed safely.

8. QuestionMultiple choice

Which conclusion is supported if plants reduce the amount of soil moved by water?

Please select an answer first.

Correct answer: D

The correct answer is Plant roots help hold soil in place and reduce erosion..

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: The measured reduction in moved soil supports the role of roots in preventing erosion.
  3. Confirm the process: The correct choice is Plant roots help hold soil in place and reduce erosion..

The measured reduction in moved soil supports the role of roots in preventing erosion.

9. QuestionMultiple choice

In a test of erosion, what is the variable the student intentionally changes?

Please select an answer first.

Correct answer: A

The correct answer is The factor the student changes, such as water speed.

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: The changed factor is the independent variable in the investigation.
  3. Confirm the process: The correct choice is The factor the student changes, such as water speed.

The changed factor is the independent variable in the investigation.

10. QuestionMultiple choice

Frequently asked questions about Grade 4 Earth Processes

What is the difference between weathering and erosion?

Weathering breaks rock and other Earth materials down, while erosion moves the broken material to another place.

What is deposition?

Deposition is the process in which moving sediment is dropped or settles in a new location.
