Grade 4 Rocks and Minerals Practice Test

Build Grade 4 Science skills with five 10-question practice tests on mineral properties, rock types, rock formation, the rock cycle, fossils, investigations, and Earth material uses.

Rocks and Minerals Practice Tests

These Grade 4 Science practice tests help students classify minerals and rocks and explain how Earth materials form and change. Students use properties such as hardness, luster, streak, layers, and texture to identify samples and connect rocks to the rock cycle.

Skills covered

  • Defining minerals and identifying mineral properties
  • Distinguishing igneous, sedimentary, and metamorphic rocks
  • Explaining melting, cooling, compaction, cementation, heat, and pressure
  • Connecting fossils and layers to sedimentary rocks
  • Planning fair tests and using evidence to classify samples
  • Understanding how people use and conserve rocks and minerals

How to use these practice tests

Use more than one property when identifying a mineral or rock. For rock types, ask how the material formed: cooling melted rock, compacted sediment, or changed existing rock under heat and pressure. Use observations and measured evidence to support conclusions.

1. QuestionMultiple choice

How can sediment form?

Please select an answer first.

Correct answer: A

The correct answer is Weathering can break larger rocks into smaller pieces..

  1. Observe the material: Look for mineral properties, rock type, formation process, or evidence from an investigation.
  2. Apply the Earth science rule: Weathering produces loose pieces of rock and soil called sediment.
  3. Confirm the classification: The correct choice is Weathering can break larger rocks into smaller pieces..

Weathering produces loose pieces of rock and soil called sediment.

2. QuestionMultiple choice

What do compaction and cementation do?

Please select an answer first.

Correct answer: B

The correct answer is They press and hold sediment together to form sedimentary rock..

  1. Observe the material: Look for mineral properties, rock type, formation process, or evidence from an investigation.
  2. Apply the Earth science rule: Pressure and natural minerals can bind deposited sediment into rock.
  3. Confirm the classification: The correct choice is They press and hold sediment together to form sedimentary rock..

Pressure and natural minerals can bind deposited sediment into rock.

3. QuestionMultiple choice

Which event is an example of weathering?

Please select an answer first.

Correct answer: C

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

  1. Observe the material: Look for mineral properties, rock type, formation process, or evidence from an investigation.
  2. Apply the Earth science rule: Freezing water can break down rock by expanding inside a crack.
  3. Confirm the classification: The correct choice is Water freezes in a crack and widens the crack in a rock..

Freezing water can break down rock by expanding inside a crack.

4. QuestionMultiple choice

Which event is an example of erosion?

Please select an answer first.

Correct answer: D

The correct answer is Wind carries loose sand across a dry field..

  1. Observe the material: Look for mineral properties, rock type, formation process, or evidence from an investigation.
  2. Apply the Earth science rule: Erosion is the movement of weathered material by wind, water, ice, or gravity.
  3. Confirm the classification: The correct choice is Wind carries loose sand across a dry field..

Erosion is the movement of weathered material by wind, water, ice, or gravity.

5. QuestionMultiple choice

Which event is an example of deposition?

Please select an answer first.

Correct answer: A

The correct answer is A river drops sand where it slows near a lake..

  1. Observe the material: Look for mineral properties, rock type, formation process, or evidence from an investigation.
  2. Apply the Earth science rule: Deposition happens when transported sediment is dropped or settles.
  3. Confirm the classification: The correct choice is A river drops sand where it slows near a lake..

Deposition happens when transported sediment is dropped or settles.

6. QuestionMultiple choice

How can one rock type change into another in the rock cycle?

Please select an answer first.

Correct answer: B

The correct answer is Processes such as melting, cooling, weathering, heat, pressure, or cementation can change it..

  1. Observe the material: Look for mineral properties, rock type, formation process, or evidence from an investigation.
  2. Apply the Earth science rule: Different Earth processes create, break down, or transform rocks.
  3. Confirm the classification: The correct choice is Processes such as melting, cooling, weathering, heat, pressure, or cementation can change it..

Different Earth processes create, break down, or transform rocks.

7. QuestionMultiple choice

What happens when melted rock cools?

Please select an answer first.

Correct answer: C

The correct answer is It can form igneous rock..

  1. Observe the material: Look for mineral properties, rock type, formation process, or evidence from an investigation.
  2. Apply the Earth science rule: Cooling and hardening of magma or lava forms igneous rock.
  3. Confirm the classification: The correct choice is It can form igneous rock..

Cooling and hardening of magma or lava forms igneous rock.

8. QuestionMultiple choice

What can heat and pressure do to existing rock?

Please select an answer first.

Correct answer: D

The correct answer is They can change the rock into metamorphic rock..

  1. Observe the material: Look for mineral properties, rock type, formation process, or evidence from an investigation.
  2. Apply the Earth science rule: Heat and pressure change the minerals or texture of existing rock.
  3. Confirm the classification: The correct choice is They can change the rock into metamorphic rock..

Heat and pressure change the minerals or texture of existing rock.

9. QuestionMultiple choice

How can uplift expose rock that formed deep underground?

Please select an answer first.

Correct answer: A

The correct answer is Earth’s movement can raise buried rock closer to the surface..

  1. Observe the material: Look for mineral properties, rock type, formation process, or evidence from an investigation.
  2. Apply the Earth science rule: Movement of Earth’s crust can bring deep rock to the surface where weathering can act on it.
  3. Confirm the classification: The correct choice is Earth’s movement can raise buried rock closer to the surface..

Movement of Earth’s crust can bring deep rock to the surface where weathering can act on it.

10. QuestionMultiple choice

Which clue best suggests that a rock may be sedimentary?

Please select an answer first.

Correct answer: B

The correct answer is It has visible layers and contains a fossil..

  1. Observe the material: Look for mineral properties, rock type, formation process, or evidence from an investigation.
  2. Apply the Earth science rule: Layers and fossils are common clues for sedimentary rock.
  3. Confirm the classification: The correct choice is It has visible layers and contains a fossil..

Layers and fossils are common clues for sedimentary rock.

Frequently asked questions about Grade 4 Rocks and Minerals

How are rocks and minerals different?

A mineral is a naturally occurring inorganic solid with a definite composition, while a rock is made of one or more minerals or other Earth materials.

What are the three main rock types?

The three main rock types are igneous, sedimentary, and metamorphic. Each forms through different Earth processes.
