1. QuestionMultiple choice

What is a major result of movement at tectonic plate boundaries?

Please select an answer first.

Correct answer: A

The correct answer is Earthquakes and volcanic activity can occur.

  1. Identify the evidence: Read the model, observation, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Plate movement releases energy and can cause earthquakes or allow magma to rise.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and answers the question.

Plate movement releases energy and can cause earthquakes or allow magma to rise.

2. QuestionMultiple choice

How can sedimentary rock become metamorphic rock?

Please select an answer first.

Correct answer: B

The correct answer is Heat and pressure change the rock without melting it completely.

  1. Identify the evidence: Read the model, observation, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Metamorphic rock forms when existing rock is changed by heat and pressure.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and answers the question.

Metamorphic rock forms when existing rock is changed by heat and pressure.

3. QuestionMultiple choice

Which statement best distinguishes climate from weather?

Please select an answer first.

Correct answer: C

The correct answer is Climate describes long-term patterns, while weather describes short-term conditions.

  1. Identify the evidence: Read the model, observation, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Weather is observed over hours or days; climate summarizes patterns over much longer periods.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and answers the question.

Weather is observed over hours or days; climate summarizes patterns over much longer periods.

4. QuestionMultiple choice

How can an increase in greenhouse gases affect Earth systems?

Please select an answer first.

Correct answer: D

The correct answer is More outgoing heat may be retained in the atmosphere.

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

Greenhouse gases absorb and re-emit some infrared radiation, affecting energy balance.

5. QuestionMultiple choice

Which process adds carbon dioxide to the atmosphere?

Please select an answer first.

Correct answer: A

The correct answer is Combustion of fossil fuels.

  1. Identify the evidence: Read the model, observation, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Burning fossil fuels releases stored carbon as carbon dioxide.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and answers the question.

Burning fossil fuels releases stored carbon as carbon dioxide.

6. QuestionMultiple choice

What role does evaporation play in the water cycle?

Please select an answer first.

Correct answer: B

The correct answer is It moves liquid water into the atmosphere as vapor.

  1. Identify the evidence: Read the model, observation, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Evaporation transfers water from surfaces to the atmosphere.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and answers the question.

Evaporation transfers water from surfaces to the atmosphere.

7. QuestionMultiple choice

Why do seasons occur on Earth?

Please select an answer first.

Correct answer: C

The correct answer is The tilted axis changes the angle and duration of sunlight.

  1. Identify the evidence: Read the model, observation, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Earth's tilt changes how directly sunlight reaches each hemisphere during its orbit.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and answers the question.

Earth's tilt changes how directly sunlight reaches each hemisphere during its orbit.

8. QuestionMultiple choice

Why does the Moon show phases?

Please select an answer first.

Correct answer: D

The correct answer is The visible portion of its sunlit half changes as it orbits Earth.

  1. Identify the evidence: Read the model, observation, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: The Moon always reflects sunlight, but its position changes the portion we see illuminated.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and answers the question.

The Moon always reflects sunlight, but its position changes the portion we see illuminated.

9. QuestionMultiple choice

Which energy source is renewable on a human time scale?

Please select an answer first.

Correct answer: A

The correct answer is Wind.

  1. Identify the evidence: Read the model, observation, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Wind is continually replenished, unlike fossil fuels.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and answers the question.

Wind is continually replenished, unlike fossil fuels.

10. QuestionMultiple choice

What can scientists learn from a sequence of rock layers?

Please select an answer first.

Correct answer: B

The correct answer is The relative order of events in Earth history.

  1. Identify the evidence: Read the model, observation, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Rock layers and fossils provide evidence for relative ages and past environments.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and answers the question.

Rock layers and fossils provide evidence for relative ages and past environments.
