Grade 5 Environmental Science Quiz

Explain how deforestation impacts the environment.

• Deforestation has no impact on the environment

• Deforestation impacts the environment by causing loss of habitat, soil erosion, disruption of the water cycle, and increased greenhouse gas emissions.

• Deforestation helps in maintaining the water cycle

• Deforestation leads to increased biodiversity

Describe the effects of industrial pollution on the environment.

• Industrial pollution can have various negative effects on the environment such as air and water pollution, soil contamination, and harm to wildlife.

• Industrial pollution helps in the growth of plants

• Industrial pollution has no impact on the environment

• Industrial pollution leads to increased biodiversity

How do human activities contribute to climate change?

• Human activities reduce greenhouse gases in the atmosphere

• Human activities have no impact on climate change

• Human activities only release oxygen into the atmosphere

• Human activities release greenhouse gases into the atmosphere

What are the consequences of overfishing on marine ecosystems?

• Increase in fish populations, strengthening of food chains, and increase in biodiversity

• No impact on fish populations, no change in food chains, and no effect on biodiversity

• Depletion of fish populations, disruption of food chains, and loss of biodiversity

• Decrease in fish populations, strengthening of food chains, and increase in biodiversity

Explain the impact of plastic pollution on wildlife and the environment.

• Plastic pollution can harm wildlife by entangling animals and causing ingestion of plastic, leading to injury or death. It also contaminates the environment, affecting ecosystems and water sources.

• Plastic pollution has a positive impact on the environment by reducing waste

• Plastic pollution has no impact on wildlife or the environment

• Plastic pollution helps wildlife by providing shelter and food sources

What are the effects of air pollution on human health?

• Enhanced cardiovascular health

• Respiratory problems, heart disease, and other health issues

• Decreased risk of respiratory problems

• Improved immune system

Describe the impact of water pollution on aquatic life.

• It can harm aquatic life by reducing oxygen levels, introducing toxins, and disrupting the food chain.

• It only affects one species of aquatic life

• It can improve the health of aquatic life

• It has no impact on aquatic life

How does the pollution of rivers and lakes affect the ecosystem?

• It can harm the plants and animals that depend on these water sources for survival and disrupt the balance of the ecosystem.

• It improves the balance of the ecosystem

• It helps the plants and animals thrive

• It has no impact on the ecosystem

What are the consequences of oil spills on marine environments?

• Benefit marine life, improve habitats, and purify water and shorelines

• Enhance marine life, create new habitats, and clean water and shorelines

• Have no impact on marine life, habitats, water, and shorelines

• Harm marine life, damage habitats, and contaminate water and shorelines

Explain the effects of agricultural runoff on water quality.

• Agricultural runoff can introduce pollutants such as pesticides, fertilizers, and animal waste into water bodies, leading to decreased water quality.

• Agricultural runoff only improves water quality

• Agricultural runoff has no impact on water quality

• Agricultural runoff reduces the risk of water pollution
