Unit 10 Renewable and NonRenewable Resources

Front

What are renewable resources?

Back

Renewable resources are natural resources that can be replenished naturally over time, such as solar energy, wind energy, and hydroelectric power.

Front

What are nonrenewable resources?

Back

Nonrenewable resources are natural resources that cannot be replenished within a human timescale, such as fossil fuels (coal, oil, natural gas) and minerals.

Front

What is hydroelectric energy?

Back

Hydroelectric energy is electricity generated by harnessing the power of flowing water, typically from rivers or dams.

Front

Front

How does plastic pollution affect marine life?

Back

Plastic pollution can harm marine life by causing ingestion, entanglement, and habitat degradation, leading to decreased populations of affected species.

Front

What is the role of photosynthesis in marine ecosystems?

Back

Photosynthesis is crucial in marine ecosystems as it provides oxygen and is the foundation of the food web, supporting various marine organisms.

Front

What are the advantages of renewable energy sources?

Back

Advantages of renewable energy sources include sustainability, lower environmental impact, and reduced greenhouse gas emissions.
