Earth and Space Science Practice Test

Build high school Earth and Space Science skills with original questions on Earth systems, atmosphere, climate, geology, astronomy, hazards, resources, data, and evidence.

Earth and Space Science practice sets

This high school Earth and Space Science practice hub includes five short sets of 10 original questions. The sets move from Earth systems and cycles to atmosphere and climate, geology and plate tectonics, astronomy and Earth history, and human impacts, resources, hazards, and data interpretation.

Course scope and standards

The course connects Earth materials and systems, plate tectonics, weather and climate, the hydrologic and carbon cycles, natural hazards, human activity, Earth history, gravity and orbital motion, stellar evidence, and the history of the universe. Expectations vary by state, school, and course sequence. The topic structure is aligned as a supplemental study map to the high-school Earth and Space Science disciplinary core ideas in the Next Generation Science Standards DCI arrangements, including HS-ESS1 Earth’s Place in the Universe and HS-ESS2 Earth’s Systems.

Skills covered

  • Use models to explain interactions among the atmosphere, hydrosphere, geosphere, biosphere, and space systems
  • Interpret graphs, maps, spectra, time series, uncertainty, and evidence from investigations
  • Explain plate tectonics, weathering, erosion, groundwater, the rock cycle, and Earth history
  • Connect gravity, orbital motion, seasons, eclipses, spectra, redshift, and planetary evidence
  • Evaluate hazards, resource decisions, climate feedbacks, human impacts, and sustainable solutions

How to use these practice tests

Start with the set that matches your current unit. For missed questions, name the system, process, or evidence involved before reviewing the explanation. When a prompt includes data, check variables, units, time period, uncertainty, and whether the evidence supports correlation or a causal claim.

These are original supplemental practice questions. They are not an official state assessment, school examination, NGSS test, or test-provider assessment. Confirm your course standards, assessment blueprint, laboratory expectations, and accommodations with your teacher or school.

1. QuestionMultiple choice

What happens at a divergent plate boundary?

Please select an answer first.

Correct answer: A

The correct answer is Plates move apart and new crust can form as material rises and cools.

  1. Identify the Earth and space system: Determine whether the question concerns Earth materials, surface processes, atmosphere, climate, astronomy, hazards, resources, or evidence.
  2. Connect the evidence: Divergence at ridges or rifts can create new crust through upwelling and solidification.
  3. Check the relationship: Compare the answer with the stated model, observation, data pattern, or physical process before choosing.

Divergence at ridges or rifts can create new crust through upwelling and solidification.

2. QuestionMultiple choice

What is a common result of a convergent oceanic-continental boundary?

Please select an answer first.

Correct answer: B

The correct answer is The denser oceanic plate can subduct beneath the continental plate.

  1. Identify the Earth and space system: Determine whether the question concerns Earth materials, surface processes, atmosphere, climate, astronomy, hazards, resources, or evidence.
  2. Connect the evidence: Density differences can drive subduction, producing trenches, earthquakes, and volcanic activity.
  3. Check the relationship: Compare the answer with the stated model, observation, data pattern, or physical process before choosing.

Density differences can drive subduction, producing trenches, earthquakes, and volcanic activity.

3. QuestionMultiple choice

What evidence supports seafloor spreading?

Please select an answer first.

Correct answer: C

The correct answer is Symmetric magnetic patterns and increasing crust age away from a mid-ocean ridge.

  1. Identify the Earth and space system: Determine whether the question concerns Earth materials, surface processes, atmosphere, climate, astronomy, hazards, resources, or evidence.
  2. Connect the evidence: New crust records magnetic reversals and becomes older with distance from the ridge.
  3. Check the relationship: Compare the answer with the stated model, observation, data pattern, or physical process before choosing.

New crust records magnetic reversals and becomes older with distance from the ridge.

4. QuestionMultiple choice

What is weathering?

Please select an answer first.

Correct answer: D

The correct answer is The breakdown or alteration of rock at or near Earth’s surface.

  1. Identify the Earth and space system: Determine whether the question concerns Earth materials, surface processes, atmosphere, climate, astronomy, hazards, resources, or evidence.
  2. Connect the evidence: Weathering can be mechanical or chemical and prepares material for erosion and soil formation.
  3. Check the relationship: Compare the answer with the stated model, observation, data pattern, or physical process before choosing.

Weathering can be mechanical or chemical and prepares material for erosion and soil formation.

5. QuestionMultiple choice

How is erosion different from weathering?

Please select an answer first.

Correct answer: A

The correct answer is Erosion transports weathered material from one place to another.

  1. Identify the Earth and space system: Determine whether the question concerns Earth materials, surface processes, atmosphere, climate, astronomy, hazards, resources, or evidence.
  2. Connect the evidence: Weathering breaks down or alters material; erosion moves it by water, wind, ice, or gravity.
  3. Check the relationship: Compare the answer with the stated model, observation, data pattern, or physical process before choosing.

Weathering breaks down or alters material; erosion moves it by water, wind, ice, or gravity.

6. QuestionMultiple choice

What does the rock cycle show?

Please select an answer first.

Correct answer: B

The correct answer is Rocks can change among igneous, sedimentary, and metamorphic forms through linked processes.

  1. Identify the Earth and space system: Determine whether the question concerns Earth materials, surface processes, atmosphere, climate, astronomy, hazards, resources, or evidence.
