APES Human Impact on the Environment — Questions and Answers
Question 1: What is one major cause of habitat destruction worldwide?
- Composting
- Deforestation (Correct answer)
- Conservation
- Crop rotation
Correct answer: Deforestation
Deforestation for agriculture and development is a leading cause of habitat loss, reducing biodiversity.
Question 2: How does the burning of fossil fuels affect the atmosphere?
- Cools the atmosphere
- Removes nitrogen
- Releases carbon dioxide (Correct answer)
- Increases oxygen levels
Correct answer: Releases carbon dioxide
Burning fossil fuels releases carbon dioxide, a greenhouse gas that contributes to climate change.
Question 3: Which practice can lead to the depletion of aquifers?
- Rainwater harvesting
- Surface water recycling
- Over-pumping groundwater (Correct answer)
- Desalination
Correct answer: Over-pumping groundwater
Overdrawing groundwater for agriculture and urban use can lead to aquifer depletion and land subsidence.
Question 4: What is a consequence of excessive fertilizer use?
- Increased biodiversity
- Algal blooms and dead zones (Correct answer)
- Improved water clarity
- Less plant growth
Correct answer: Algal blooms and dead zones
Runoff from fertilizers can lead to eutrophication, which causes algal blooms and oxygen depletion in water bodies.
Question 5: What is one effect of urban sprawl?
- Increased forest cover
- Reduced greenhouse emissions
- Increased habitat fragmentation (Correct answer)
- Lower energy demand
Correct answer: Increased habitat fragmentation
Urban sprawl leads to increased land use, loss of natural habitats, and greater reliance on vehicles.
Question 6: How does plastic pollution primarily affect marine ecosystems?
- It fertilizes coral reefs
- It promotes fish growth
- It endangers marine wildlife (Correct answer)
- It improves water temperature
Correct answer: It endangers marine wildlife
Marine animals can ingest or become entangled in plastic debris, leading to injury or death.
