Multiple choice

What is the primary environmental concern associated with the use of solar panels?

  1. They produce greenhouse gases

  2. They require large amounts of land

  3. They use toxic materials

  4. They generate noise pollution
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The primary environmental concern associated with the use of solar panels is that they use toxic materials. Solar panels contain materials such as cadmium, lead, and arsenic, which can be harmful to the environment if not properly disposed of.

Multiple choice

Which of the following is a potential environmental impact of solar energy?

  1. Habitat loss

  2. Water pollution

  3. Air pollution

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All of the above are potential environmental impacts of solar energy. Habitat loss can occur when solar farms are built in areas that are home to wildlife. Water pollution can occur when solar panels are not properly disposed of. Air pollution can occur when solar panels are manufactured using toxic materials.
