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 is a renewable resource?

Please select an answer first.

Correct answer: A

The correct answer is A resource replenished by natural processes on a human-use time scale when managed carefully.

  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: Renewability depends on replenishment rate, demand, and management rather than on the resource being automatically unlimited.
  3. Check the relationship: Compare the answer with the stated model, observation, data pattern, or physical process before choosing.

Renewability depends on replenishment rate, demand, and management rather than on the resource being automatically unlimited.

2. QuestionMultiple choice

Why can groundwater depletion be a problem?

Please select an answer first.

Correct answer: B

The correct answer is Withdrawal can exceed recharge, lowering the water table and reducing available supply.

  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: A deficit between withdrawal and recharge can reduce storage and affect connected systems.
  3. Check the relationship: Compare the answer with the stated model, observation, data pattern, or physical process before choosing.

A deficit between withdrawal and recharge can reduce storage and affect connected systems.

3. QuestionMultiple choice

What is a natural hazard?

Please select an answer first.

Correct answer: C

The correct answer is A natural process or event that can threaten people, infrastructure, or ecosystems.

  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: Hazard describes potential harm; risk also depends on exposure, vulnerability, and preparedness.
  3. Check the relationship: Compare the answer with the stated model, observation, data pattern, or physical process before choosing.

Hazard describes potential harm; risk also depends on exposure, vulnerability, and preparedness.

4. QuestionMultiple choice

Which action can reduce earthquake risk?

Please select an answer first.

Correct answer: D

The correct answer is Use hazard maps, stronger building design, preparedness plans, and emergency communication.

  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: Risk reduction combines knowledge, engineering, planning, and public preparedness.
  3. Check the relationship: Compare the answer with the stated model, observation, data pattern, or physical process before choosing.

Risk reduction combines knowledge, engineering, planning, and public preparedness.

5. QuestionMultiple choice

What does carrying capacity refer to in a resource system?

Please select an answer first.

Correct answer: A

The correct answer is The level of use a system can sustain without long-term loss of its ability to provide the resource.

  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: Carrying capacity depends on regeneration, limits, demand, and the condition of the system.
  3. Check the relationship: Compare the answer with the stated model, observation, data pattern, or physical process before choosing.

Carrying capacity depends on regeneration, limits, demand, and the condition of the system.

6. QuestionMultiple choice

How can land-use change increase flooding?

Please select an answer first.

Correct answer: B

The correct answer is Removing vegetation and adding impervious surfaces can increase runoff and reduce infiltration.

  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: Less infiltration and more rapid runoff can raise peak flow during storms.
