Understanding Our Environment

What are some major effects of climate change?

• More stable weather patterns

• Major effects of climate change include extreme weather events, rising sea levels, loss of biodiversity, and impacts on agriculture and human health.

• Increased use of fossil fuels

• Improved agricultural yields

How does biodiversity contribute to ecosystem stability?

• Biodiversity has no impact on ecosystem recovery from disturbances.

• Biodiversity contributes to ecosystem stability by increasing resilience, promoting functional redundancy, and enhancing recovery from disturbances.

• Biodiversity reduces the variety of species in an ecosystem.

• Biodiversity decreases ecosystem resilience by creating competition.

What are the primary sources of pollution affecting air quality?

• Water pollution from rivers

• Vehicle emissions, industrial discharges, burning of fossil fuels, agricultural activities, and natural events.

• Household waste disposal

• Noise pollution from traffic

Name two renewable energy sources and their benefits.

• Coal energy and its abundance

• Nuclear energy and its waste management

• Natural gas and its cost-effectiveness

• Solar energy and wind energy

What is the impact of plastic pollution on marine life?

• Plastic pollution improves marine habitats.

• Marine life thrives on plastic materials.

• Plastic pollution harms marine life by causing ingestion, entanglement, and habitat degradation.

• Plastic pollution has no effect on marine ecosystems.

How can reforestation help combat climate change?

• Reforestation helps combat climate change by absorbing carbon dioxide and restoring ecosystems.

• Reforestation only benefits local wildlife without affecting climate change.

• Reforestation has no impact on climate change or ecosystems.

• Reforestation increases carbon emissions and degrades ecosystems.

What are some effective techniques for water conservation at home?

• Leaving the tap running while brushing teeth

• Watering plants during the hottest part of the day

• Using a hose instead of a broom to clean driveways

• Effective techniques for water conservation at home include fixing leaks, using water-efficient fixtures, collecting rainwater, reducing shower time, and using mulch in gardens.

How does climate change affect global weather patterns?

• Climate change has no impact on weather patterns.

• Climate change only affects local weather, not global patterns.

• Climate change disrupts global weather patterns, causing more extreme weather events and altering precipitation and temperature distributions.

• Climate change leads to a decrease in global temperatures.

What role do wetlands play in biodiversity conservation?

• Wetlands are mainly used for urban development.

• Wetlands have no impact on species diversity.

• Wetlands primarily serve as agricultural land.

• Wetlands play a vital role in biodiversity conservation by providing habitats, supporting species diversity, and maintaining ecological balance.

What are the advantages of using solar energy over fossil fuels?

• Solar energy is more expensive than fossil fuels.

• Solar energy requires more land than fossil fuels.

• Solar energy is not available during the night.

• Advantages of solar energy over fossil fuels include being renewable, environmentally friendly, reducing emissions, and potentially lowering energy costs.
