Environmental Science Practice Tests

These Grade 11 Science practice tests examine ecosystems, populations, succession, nutrient cycles, climate change, pollution, renewable and nonrenewable resources, sustainability, conservation, environmental justice, and data analysis.

Skills covered

  • Analyzing ecosystems, food webs, limiting factors, succession, niches, biodiversity, and invasive species
  • Explaining carbon, nitrogen, and water cycles, greenhouse gases, albedo, ocean acidification, and climate feedbacks
  • Comparing energy resources, life-cycle impacts, sustainability, recycling, commons, and environmental justice
  • Evaluating climate mitigation and adaptation, conservation corridors, pollution, and resource trade-offs
  • Interpreting controls, sampling, correlation, causation, uncertainty, units, and environmental data

How to use these practice tests

Define the environmental system and time scale first. Identify the relevant evidence, distinguish correlation from causation, and consider trade-offs, uncertainty, and effects on future generations.

1. QuestionMultiple choice

What is the primary cause of current human-driven global warming?

Please select an answer first.

Correct answer: A

The correct answer is Increased greenhouse gas emissions from human activities.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Burning fossil fuels, land-use change, and other activities increase greenhouse gas concentrations and alter radiative balance.
  3. Check scale and evidence: The correct answer is Increased greenhouse gas emissions from human activities.

Burning fossil fuels, land-use change, and other activities increase greenhouse gas concentrations and alter radiative balance.

2. QuestionMultiple choice

What is climate?

Please select an answer first.

Correct answer: B

The correct answer is The long-term pattern of weather in a region.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Climate describes long-term averages and variability of weather, while weather describes short-term conditions.
  3. Check scale and evidence: The correct answer is The long-term pattern of weather in a region.

Climate describes long-term averages and variability of weather, while weather describes short-term conditions.

3. QuestionMultiple choice

What is a feedback loop in climate science?

Please select an answer first.

Correct answer: C

The correct answer is A process in which a change influences effects that can amplify or reduce the original change.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Feedbacks such as ice-albedo or water-vapor feedback can alter the magnitude of an initial climate forcing.
  3. Check scale and evidence: The correct answer is A process in which a change influences effects that can amplify or reduce the original change.

Feedbacks such as ice-albedo or water-vapor feedback can alter the magnitude of an initial climate forcing.

4. QuestionMultiple choice

What is ocean acidification primarily associated with?

Please select an answer first.

Correct answer: D

The correct answer is Absorption of atmospheric carbon dioxide and formation of carbonic acid.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Dissolved carbon dioxide forms carbonic acid and can lower pH, affecting organisms that build calcium carbonate structures.
  3. Check scale and evidence: The correct answer is Absorption of atmospheric carbon dioxide and formation of carbonic acid.

Dissolved carbon dioxide forms carbonic acid and can lower pH, affecting organisms that build calcium carbonate structures.

5. QuestionMultiple choice

Why does melting sea ice differ from melting a land ice sheet in its direct sea-level effect?

Please select an answer first.

Correct answer: A

The correct answer is Floating sea ice already displaces seawater, while land ice adds water to the ocean.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Melting floating ice has little direct effect on sea level, whereas melting land-based ice transfers additional water to the ocean.
  3. Check scale and evidence: The correct answer is Floating sea ice already displaces seawater, while land ice adds water to the ocean.

Melting floating ice has little direct effect on sea level, whereas melting land-based ice transfers additional water to the ocean.

6. QuestionMultiple choice

What is an example of climate adaptation?

Please select an answer first.

Correct answer: B

The correct answer is Building infrastructure or changing practices to reduce harm from expected impacts.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Adaptation reduces vulnerability to impacts, while mitigation addresses the causes by reducing greenhouse gas emissions.
  3. Check scale and evidence: The correct answer is Building infrastructure or changing practices to reduce harm from expected impacts.

Adaptation reduces vulnerability to impacts, while mitigation addresses the causes by reducing greenhouse gas emissions.

7. QuestionMultiple choice

What is climate mitigation?

Please select an answer first.

Correct answer: C

The correct answer is Reducing greenhouse gas emissions or increasing carbon removal.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Mitigation targets the drivers of climate change through cleaner energy, efficiency, conservation, and carbon sinks.
  3. Check scale and evidence: The correct answer is Reducing greenhouse gas emissions or increasing carbon removal.

Mitigation targets the drivers of climate change through cleaner energy, efficiency, conservation, and carbon sinks.

8. QuestionMultiple choice

Why do urban areas often experience heat-island effects?
