Earth Systems Practice Tests

These Grade 7 Science practice tests build understanding of Earth's layers, spheres, minerals, rocks, rock cycles, plate tectonics, weathering, erosion, deposition, geologic time, and natural resources.

Skills covered

  • Describing Earth's layers and interactions among the geosphere, hydrosphere, atmosphere, and biosphere
  • Identifying minerals, rock types, the rock cycle, and mineral properties
  • Explaining divergent, convergent, and transform plate boundaries
  • Distinguishing weathering, erosion, and deposition in surface processes
  • Using fossils, layers, resources, and multiple lines of evidence to interpret Earth history

How to use these practice tests

For each question, identify the Earth layer, material, or process involved. Then connect the evidence to the movement of matter and energy over the time scale described.

1. QuestionMultiple choice

What is geologic time?

Please select an answer first.

Correct answer: A

The correct answer is The long time scale used to describe Earth's history and changes..

  1. Identify the Earth-system process: Determine whether the question involves Earth layers, rocks, minerals, plate movement, surface processes, resources, or geologic time.
  2. Connect the evidence: Geologic time covers billions of years and helps organize Earth's formation, life, rocks, and events.
  3. Check the system interaction: Earth materials and processes interact over time, so connect the observation to the layer, cycle, force, or surface change involved.

Geologic time covers billions of years and helps organize Earth's formation, life, rocks, and events.

2. QuestionMultiple choice

What is relative dating?

Please select an answer first.

Correct answer: B

The correct answer is Determining whether a rock or event is older or younger than another..

  1. Identify the Earth-system process: Determine whether the question involves Earth layers, rocks, minerals, plate movement, surface processes, resources, or geologic time.
  2. Connect the evidence: Relative dating places events in order without necessarily assigning a numerical age.
  3. Check the system interaction: Earth materials and processes interact over time, so connect the observation to the layer, cycle, force, or surface change involved.

Relative dating places events in order without necessarily assigning a numerical age.

3. QuestionMultiple choice

What does the principle of superposition state for undisturbed sedimentary layers?

Please select an answer first.

Correct answer: C

The correct answer is Lower layers are generally older than layers above them..

  1. Identify the Earth-system process: Determine whether the question involves Earth layers, rocks, minerals, plate movement, surface processes, resources, or geologic time.
  2. Connect the evidence: In undisturbed sedimentary rock, newer deposits accumulate above older deposits.
  3. Check the system interaction: Earth materials and processes interact over time, so connect the observation to the layer, cycle, force, or surface change involved.

In undisturbed sedimentary rock, newer deposits accumulate above older deposits.

4. QuestionMultiple choice

What is a fossil?

Please select an answer first.

Correct answer: D

The correct answer is Preserved evidence of past life or its activity.

  1. Identify the Earth-system process: Determine whether the question involves Earth layers, rocks, minerals, plate movement, surface processes, resources, or geologic time.
  2. Connect the evidence: Fossils include body parts, impressions, tracks, burrows, and other evidence preserved in rock or sediment.
  3. Check the system interaction: Earth materials and processes interact over time, so connect the observation to the layer, cycle, force, or surface change involved.

Fossils include body parts, impressions, tracks, burrows, and other evidence preserved in rock or sediment.

5. QuestionMultiple choice

Why are index fossils useful for comparing rock layers?

Please select an answer first.

Correct answer: A

The correct answer is They were widespread and lived for a relatively short geologic time..

  1. Identify the Earth-system process: Determine whether the question involves Earth layers, rocks, minerals, plate movement, surface processes, resources, or geologic time.
  2. Connect the evidence: A widespread short-lived species can help match the relative ages of layers in different locations.
  3. Check the system interaction: Earth materials and processes interact over time, so connect the observation to the layer, cycle, force, or surface change involved.

A widespread short-lived species can help match the relative ages of layers in different locations.

6. QuestionMultiple choice

What is a renewable resource?

Please select an answer first.

Correct answer: B

The correct answer is A resource that can be replenished naturally on a human time scale.

  1. Identify the Earth-system process: Determine whether the question involves Earth layers, rocks, minerals, plate movement, surface processes, resources, or geologic time.
  2. Connect the evidence: Sunlight, wind, and many biological resources can be renewed when managed appropriately.
  3. Check the system interaction: Earth materials and processes interact over time, so connect the observation to the layer, cycle, force, or surface change involved.

Sunlight, wind, and many biological resources can be renewed when managed appropriately.

7. QuestionMultiple choice

Which is a nonrenewable resource?

Please select an answer first.

Correct answer: C

The correct answer is Coal.

  1. Identify the Earth-system process: Determine whether the question involves Earth layers, rocks, minerals, plate movement, surface processes, resources, or geologic time.
  2. Connect the evidence: Coal forms over very long geologic times and is used much faster than it is naturally replaced.
  3. Check the system interaction: Earth materials and processes interact over time, so connect the observation to the layer, cycle, force, or surface change involved.

Coal forms over very long geologic times and is used much faster than it is naturally replaced.

8. QuestionMultiple choice

Why can groundwater become a limited resource?

Please select an answer first.

Correct answer: D

The correct answer is Water may be withdrawn faster than precipitation can recharge the aquifer..

  1. Identify the Earth-system process: Determine whether the question involves Earth layers, rocks, minerals, plate movement, surface processes, resources, or geologic time.
  2. Connect the evidence: Groundwater is renewable in many places, but its supply can decline when pumping exceeds recharge.
  3. Check the system interaction: Earth materials and processes interact over time, so connect the observation to the layer, cycle, force, or surface change involved.

Groundwater is renewable in many places, but its supply can decline when pumping exceeds recharge.

9. QuestionMultiple choice

Which practice best conserves mineral resources?

Please select an answer first.

Correct answer: A

The correct answer is Reducing waste, reusing materials, and recycling products.

  1. Identify the Earth-system process: Determine whether the question involves Earth layers, rocks, minerals, plate movement, surface processes, resources, or geologic time.
