1. QuestionMultiple choice

What causes day and night on Earth?

Please select an answer first.

Correct answer: A

The correct answer is Earth rotates on its axis.

  1. Identify the evidence: Read the scenario, model, or data and identify the scientific evidence provided.
  2. Apply the science idea: Rotation brings different parts of Earth into and out of sunlight.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Rotation brings different parts of Earth into and out of sunlight.

2. QuestionMultiple choice

What is the difference between weather and climate?

Please select an answer first.

Correct answer: B

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

  1. Identify the evidence: Read the scenario, model, or data and identify the scientific evidence provided.
  2. Apply the science idea: Weather changes over hours or days; climate summarizes patterns over many years.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Weather changes over hours or days; climate summarizes patterns over many years.

3. QuestionMultiple choice

Which process moves liquid water into the atmosphere?

Please select an answer first.

Correct answer: C

The correct answer is Evaporation.

  1. Identify the evidence: Read the scenario, model, or data and identify the scientific evidence provided.
  2. Apply the science idea: Evaporation changes liquid water into water vapor.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Evaporation changes liquid water into water vapor.

4. QuestionMultiple choice

What can occur where tectonic plates move past one another?

Please select an answer first.

Correct answer: D

The correct answer is Earthquakes.

  1. Identify the evidence: Read the scenario, model, or data and identify the scientific evidence provided.
  2. Apply the science idea: Movement and friction along plate boundaries can release energy as earthquakes.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Movement and friction along plate boundaries can release energy as earthquakes.

5. QuestionMultiple choice

How can increased greenhouse gases affect Earth?

Please select an answer first.

Correct answer: A

The correct answer is They can increase heat retained in the atmosphere.

  1. Identify the evidence: Read the scenario, model, or data and identify the scientific evidence provided.
  2. Apply the science idea: Greenhouse gases absorb and re-emit some outgoing infrared energy.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Greenhouse gases absorb and re-emit some outgoing infrared energy.

6. QuestionMultiple choice

Which energy source is renewable?

Please select an answer first.

Correct answer: B

The correct answer is Solar energy.

  1. Identify the evidence: Read the scenario, model, or data and identify the scientific evidence provided.
  2. Apply the science idea: Sunlight is replenished naturally on a human time scale.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Sunlight is replenished naturally on a human time scale.

7. QuestionMultiple choice

Why does the Moon appear to have phases?

Please select an answer first.

Correct answer: C

The correct answer is We see different portions of its sunlit half as it orbits Earth.

  1. Identify the evidence: Read the scenario, model, or data and identify the scientific evidence provided.
  2. Apply the science idea: The illuminated portion visible from Earth changes with the Moon's position.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

The illuminated portion visible from Earth changes with the Moon's position.

8. QuestionMultiple choice

What process can carry soil away from a hillside?

Please select an answer first.

Correct answer: D

The correct answer is Erosion by moving water.

  1. Identify the evidence: Read the scenario, model, or data and identify the scientific evidence provided.
  2. Apply the science idea: Moving water can loosen and transport soil particles.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Moving water can loosen and transport soil particles.

9. QuestionMultiple choice

What can scientists learn from ice cores?

Please select an answer first.

Correct answer: A

The correct answer is Evidence about past atmospheric gases and climate conditions.

  1. Identify the evidence: Read the scenario, model, or data and identify the scientific evidence provided.
  2. Apply the science idea: Trapped gases and layers preserve evidence of past environments.
