1. QuestionMultiple choice

Which process removes carbon dioxide from the atmosphere for a time?

Please select an answer first.

Correct answer: A

The correct answer is Photosynthesis by plants and algae.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Photosynthesis uses carbon dioxide to build organic molecules, storing carbon in living matter.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Photosynthesis uses carbon dioxide to build organic molecules, storing carbon in living matter.

2. QuestionMultiple choice

Which observation is evidence of climate change rather than a single weather event?

Please select an answer first.

Correct answer: B

The correct answer is A long-term increase in average temperature across many years.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Climate describes long-term patterns, so trends over many years provide stronger climate evidence than one event.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Climate describes long-term patterns, so trends over many years provide stronger climate evidence than one event.

3. QuestionMultiple choice

What occurs at a subduction zone?

Please select an answer first.

Correct answer: C

The correct answer is One tectonic plate moves beneath another into the mantle.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: At a subduction zone, a denser plate is forced beneath another plate, producing earthquakes, volcanoes, and other changes.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

At a subduction zone, a denser plate is forced beneath another plate, producing earthquakes, volcanoes, and other changes.

4. QuestionMultiple choice

Why can a climate model be useful even though it is not a perfect copy of Earth?

Please select an answer first.

Correct answer: D

The correct answer is It can represent relationships and test possible future scenarios.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Models simplify complex systems so scientists can examine relationships and explore possible outcomes.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Models simplify complex systems so scientists can examine relationships and explore possible outcomes.

5. QuestionMultiple choice

How can ocean currents affect regional climate?

Please select an answer first.

Correct answer: A

The correct answer is They transport thermal energy and influence nearby air temperatures.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Moving ocean water transfers heat and can influence air temperature, moisture, and weather patterns near coasts.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Moving ocean water transfers heat and can influence air temperature, moisture, and weather patterns near coasts.

6. QuestionMultiple choice

Why does melting snow or sea ice create an albedo feedback?

Please select an answer first.

Correct answer: B

The correct answer is Less reflective surface absorbs more solar energy.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Bright snow and ice reflect much incoming energy, while darker land or water absorbs more, which can increase warming.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Bright snow and ice reflect much incoming energy, while darker land or water absorbs more, which can increase warming.

7. QuestionMultiple choice

How can Earth axis tilt influence climate patterns over a year?

Please select an answer first.

Correct answer: C

The correct answer is It changes the angle and length of sunlight received by each hemisphere.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Axis tilt changes solar intensity and daylight duration as Earth orbits the Sun.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Axis tilt changes solar intensity and daylight duration as Earth orbits the Sun.

8. QuestionMultiple choice

What is an aquifer?

Please select an answer first.

Correct answer: D

The correct answer is An underground layer of permeable material that stores and transmits groundwater.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Aquifers contain groundwater in connected pores or fractures and can supply wells or springs.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Aquifers contain groundwater in connected pores or fractures and can supply wells or springs.

9. QuestionMultiple choice

What determines the main path a star follows during its life?

Please select an answer first.

Correct answer: A

The correct answer is Its initial mass.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: A star initial mass strongly influences its fuel use, lifetime, and later stages of development.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

A star initial mass strongly influences its fuel use, lifetime, and later stages of development.

10. QuestionMultiple choice

What causes a lunar eclipse?

Please select an answer first.

Correct answer: B

The correct answer is Earth moves between the Sun and the Moon and casts a shadow on the Moon.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: A lunar eclipse occurs when the Moon passes through Earth shadow during a suitable alignment.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

A lunar eclipse occurs when the Moon passes through Earth shadow during a suitable alignment.
