3.4 Energy And The Environment

Question 1

Name two problems caused by burning fossil fuels.

Answer 1

1) Release of greenhouse gases like carbon dioxide, contributing to global warming.
2) Production of sulfur dioxide, which can cause acid rain.

Question 2

What is one advantage of nuclear power compared to fossil fuels?

Answer 2

Nuclear power produces no greenhouse gases during energy production.

Question 3

What is one disadvantage of nuclear power?

Answer 3

It produces radioactive waste that must be stored safely for long periods.

Question 4

List two advantages of renewable energy sources.

Answer 4

1) They will never run out because they are always being replenished by natural processes.
2)They do not create radioactive waste products.

Question 5

List two disadvantages of renewable energy sources.

Answer 5

1)Renewable energy resources are not currently able to meet the world demand. So fossil fuels are still needed to provide some of the energy demand.
2)some renewable energy resources are not available all the time or can be unreliable

Question 6

List two disadvantages of renewable energy sources.

Answer 6

1) Some are weather-dependent (e.g., solar power is less effective on cloudy days).
2) Large areas of land are often needed for energy generation (e.g., solar farms, wind turbines).

Question 7

What are the environmental advantages of renewable energy sources over fossil fuels?
