1. QuestionMultiple choice

What happens at a convergent boundary where one oceanic plate moves beneath another plate?

Please select an answer first.

Correct answer: A

The correct answer is Subduction can form a trench and volcanic activity.

  1. Identify the science idea: Decide whether the question is about matter, energy, forces, cells, heredity, Earth systems, or scientific evidence.
  2. Use the evidence: At some convergent boundaries, the denser plate sinks beneath the other, forming trenches and potentially feeding volcanoes.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

At some convergent boundaries, the denser plate sinks beneath the other, forming trenches and potentially feeding volcanoes.

2. QuestionMultiple choice

What is the main cause of most earthquakes?

Please select an answer first.

Correct answer: B

The correct answer is A sudden release of stress when rocks move along a fault.

  1. Identify the science idea: Decide whether the question is about matter, energy, forces, cells, heredity, Earth systems, or scientific evidence.
  2. Use the evidence: Tectonic forces can build stress in rocks until movement along a fault releases energy as an earthquake.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Tectonic forces can build stress in rocks until movement along a fault releases energy as an earthquake.

3. QuestionMultiple choice

Which process can change igneous rock into sediment?

Please select an answer first.

Correct answer: C

The correct answer is Weathering and erosion.

  1. Identify the science idea: Decide whether the question is about matter, energy, forces, cells, heredity, Earth systems, or scientific evidence.
  2. Use the evidence: Weathering breaks rock into smaller pieces, and erosion transports the sediment to another location.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Weathering breaks rock into smaller pieces, and erosion transports the sediment to another location.

4. QuestionMultiple choice

What is the main process that returns water vapor to liquid water in the atmosphere?

Please select an answer first.

Correct answer: D

The correct answer is Condensation.

  1. Identify the science idea: Decide whether the question is about matter, energy, forces, cells, heredity, Earth systems, or scientific evidence.
  2. Use the evidence: Cooling water vapor can cause it to condense into liquid droplets that form clouds.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Cooling water vapor can cause it to condense into liquid droplets that form clouds.

5. QuestionMultiple choice

Which statement best distinguishes weather from climate?

Please select an answer first.

Correct answer: A

The correct answer is Weather describes short-term conditions, while climate describes long-term patterns.

  1. Identify the science idea: Decide whether the question is about matter, energy, forces, cells, heredity, Earth systems, or scientific evidence.
  2. Use the evidence: Weather is the condition of the atmosphere over a short time, while climate is the average pattern over many years.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Weather is the condition of the atmosphere over a short time, while climate is the average pattern over many years.

6. QuestionMultiple choice

How can increased greenhouse gases affect Earth system energy balance?

Please select an answer first.

Correct answer: B

The correct answer is They can trap more outgoing thermal energy in the atmosphere.

  1. Identify the science idea: Decide whether the question is about matter, energy, forces, cells, heredity, Earth systems, or scientific evidence.
  2. Use the evidence: Greenhouse gases absorb and re-emit some outgoing infrared energy, which can warm the lower atmosphere and surface.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Greenhouse gases absorb and re-emit some outgoing infrared energy, which can warm the lower atmosphere and surface.

7. QuestionMultiple choice

What primarily causes the seasons on Earth?

Please select an answer first.

Correct answer: C

The correct answer is Earth axis tilt as Earth orbits the Sun.

  1. Identify the science idea: Decide whether the question is about matter, energy, forces, cells, heredity, Earth systems, or scientific evidence.
  2. Use the evidence: The tilt of Earth axis changes the angle and duration of sunlight received by each hemisphere during its orbit.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

The tilt of Earth axis changes the angle and duration of sunlight received by each hemisphere during its orbit.

8. QuestionMultiple choice

During which Moon phase is a lunar eclipse possible?

Please select an answer first.

Correct answer: D

The correct answer is Full Moon.

  1. Identify the science idea: Decide whether the question is about matter, energy, forces, cells, heredity, Earth systems, or scientific evidence.
  2. Use the evidence: A lunar eclipse can occur when Earth is between the Sun and a full Moon and the Moon passes through Earth shadow.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

A lunar eclipse can occur when Earth is between the Sun and a full Moon and the Moon passes through Earth shadow.

9. QuestionMultiple choice

How can ocean currents affect coastal climate?

Please select an answer first.

Correct answer: A

The correct answer is They move thermal energy and can warm or cool nearby coastal areas.

  1. Identify the science idea: Decide whether the question is about matter, energy, forces, cells, heredity, Earth systems, or scientific evidence.
  2. Use the evidence: Ocean currents transport heat, influencing air temperatures and climate patterns near coastlines.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Ocean currents transport heat, influencing air temperatures and climate patterns near coastlines.

10. QuestionMultiple choice

Which action is most likely to conserve a limited freshwater resource?

Please select an answer first.

Correct answer: B

The correct answer is Repairing leaks and using water only when needed.

  1. Identify the science idea: Decide whether the question is about matter, energy, forces, cells, heredity, Earth systems, or scientific evidence.
  2. Use the evidence: Reducing unnecessary use and preventing leaks helps preserve freshwater supplies for people and ecosystems.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Reducing unnecessary use and preventing leaks helps preserve freshwater supplies for people and ecosystems.
