1. QuestionMultiple choice

Why can thawing permafrost affect the carbon cycle?

Please select an answer first.

Correct answer: A

The correct answer is Thawed organic matter can decompose and release carbon dioxide or methane.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Thawing exposes previously frozen organic matter to decomposition, which can release greenhouse gases.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Thawing exposes previously frozen organic matter to decomposition, which can release greenhouse gases.

2. QuestionMultiple choice

Why can salmon abundance be used as an indicator of ecosystem conditions?

Please select an answer first.

Correct answer: B

The correct answer is Salmon depend on connected river, ocean, food, and habitat conditions.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Salmon interact with multiple habitats and food webs, so changes in their abundance can reflect changes in those systems.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Salmon interact with multiple habitats and food webs, so changes in their abundance can reflect changes in those systems.

3. QuestionMultiple choice

Which observation could provide early evidence of volcanic unrest?

Please select an answer first.

Correct answer: C

The correct answer is Increasing small earthquakes together with changing gas emissions.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Changes in seismicity and volcanic gas release can indicate movement of magma or fluids beneath a volcano.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Changes in seismicity and volcanic gas release can indicate movement of magma or fluids beneath a volcano.

4. QuestionMultiple choice

What does a glacier mass balance measure?

Please select an answer first.

Correct answer: D

The correct answer is The difference between ice gained and ice lost over a period.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Mass balance compares accumulation, such as snowfall, with losses from melting, sublimation, or calving.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Mass balance compares accumulation, such as snowfall, with losses from melting, sublimation, or calving.

5. QuestionMultiple choice

Why can tidal energy be considered a predictable renewable resource?

Please select an answer first.

Correct answer: A

The correct answer is It uses repeating ocean movement caused mainly by gravitational interactions.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Tides follow predictable cycles driven mainly by the gravity of the Moon and Sun.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Tides follow predictable cycles driven mainly by the gravity of the Moon and Sun.

6. QuestionMultiple choice

A stream has nitrate readings of 2, 4, 5, 5, and 9 milligrams per liter. What is the median?

Please select an answer first.

Correct answer: B

The correct answer is 5 milligrams per liter.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: The values are already ordered, and the middle value of five readings is 5 milligrams per liter.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

The values are already ordered, and the middle value of five readings is 5 milligrams per liter.

7. QuestionMultiple choice

How can reduced sea ice influence the Arctic energy balance?

Please select an answer first.

Correct answer: C

The correct answer is More dark ocean surface can absorb solar energy that bright ice would reflect.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Sea ice has high reflectivity, while dark water absorbs more incoming solar energy.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Sea ice has high reflectivity, while dark water absorbs more incoming solar energy.

8. QuestionMultiple choice

A watershed receives a spill upstream. Which process can move the contaminant through the system?

Please select an answer first.

Correct answer: D

The correct answer is Runoff and stream flow can transport it downstream.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Water moving across land and through channels can carry dissolved or suspended contaminants through a watershed.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Water moving across land and through channels can carry dissolved or suspended contaminants through a watershed.

9. QuestionMultiple choice

A remote bridge must support a load while minimizing material use. Which evidence is most useful before construction?

Please select an answer first.

Correct answer: A

The correct answer is Results from scaled load tests of several design prototypes.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Prototype load tests provide measured evidence for comparing performance before selecting a final design.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Prototype load tests provide measured evidence for comparing performance before selecting a final design.

10. QuestionMultiple choice

Which approach gives the strongest understanding of long-term change in an Alaska ecosystem?

Please select an answer first.

Correct answer: B

The correct answer is Combine repeated instrument measurements with documented local observations.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Long-term understanding is stronger when multiple evidence sources are collected consistently and interpreted together.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Long-term understanding is stronger when multiple evidence sources are collected consistently and interpreted together.
