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 is weathering?

Please select an answer first.

Correct answer: A

The correct answer is The breaking down of rock at Earth’s surface.

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: Weathering breaks rock into smaller pieces through physical or chemical changes.
  3. Confirm the process: The correct choice is The breaking down of rock at Earth’s surface.

Weathering breaks rock into smaller pieces through physical or chemical changes.

2. QuestionMultiple choice

What is erosion?

Please select an answer first.

Correct answer: B

The correct answer is The movement of weathered rock or soil to another place.

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: Erosion transports sediment by water, wind, ice, or gravity.
  3. Confirm the process: The correct choice is The movement of weathered rock or soil to another place.

Erosion transports sediment by water, wind, ice, or gravity.

3. QuestionMultiple choice

What is deposition?

Please select an answer first.

Correct answer: C

The correct answer is The dropping or settling of sediment in a new place.

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: Deposition happens when moving sediment is dropped or settles.
  3. Confirm the process: The correct choice is The dropping or settling of sediment in a new place.

Deposition happens when moving sediment is dropped or settles.

4. QuestionMultiple choice

Which forces can cause weathering or erosion?

Please select an answer first.

Correct answer: D

The correct answer is Water, wind, ice, and gravity.

  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, wind, moving ice, and gravity can break down or move Earth materials.
  3. Confirm the process: The correct choice is Water, wind, ice, and gravity.

Water, wind, moving ice, and gravity can break down or move Earth materials.

5. QuestionMultiple choice

How can plant roots cause weathering?

Please select an answer first.

Correct answer: A

The correct answer is Roots can grow into cracks and push rock apart..

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: Growing roots can widen cracks and physically break rock.
  3. Confirm the process: The correct choice is Roots can grow into cracks and push rock apart..

Growing roots can widen cracks and physically break rock.

6. QuestionMultiple choice

What is sediment?

Please select an answer first.

Correct answer: B

The correct answer is Small pieces of rock, soil, or other Earth material.

  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 is loose material that can be moved and deposited.
  3. Confirm the process: The correct choice is Small pieces of rock, soil, or other Earth material.

Sediment is loose material that can be moved and deposited.

7. QuestionMultiple choice

How can a river form a canyon over a long time?

Please select an answer first.

Correct answer: C

The correct answer is Moving water erodes and carries away rock and soil..

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: Flowing water can wear away and transport Earth materials over long periods.
  3. Confirm the process: The correct choice is Moving water erodes and carries away rock and soil..

Flowing water can wear away and transport Earth materials over long periods.

8. QuestionMultiple choice

What happens when a river slows near its mouth?

Please select an answer first.

Correct answer: D

The correct answer is The river may deposit sediment and build a delta..

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: Slower water has less energy to carry sediment, so it can settle and form a delta.
  3. Confirm the process: The correct choice is The river may deposit sediment and build a delta..

Slower water has less energy to carry sediment, so it can settle and form a delta.

9. QuestionMultiple choice

Which process can change a rock slowly over many years?

Please select an answer first.

Correct answer: A

The correct answer is Weathering.

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: Weathering is often a slow process that breaks down rocks over time.
  3. Confirm the process: The correct choice is Weathering.

Weathering is often a slow process that breaks down rocks over time.

10. QuestionMultiple choice

Which sequence correctly describes sediment movement?

Please select an answer first.

Correct answer: B

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

  1. Identify the Earth process: Look for rock breakdown, movement of sediment, or sediment being dropped in a new place.
  2. Connect the evidence: These three processes describe breakdown, movement, and settling of Earth materials.
  3. Confirm the process: The correct choice is Weathering breaks rock, erosion moves sediment, and deposition drops it..

These three processes describe breakdown, movement, and settling of Earth materials.

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.
