Multiple choice

What is the process of using nuclear fission to generate electricity called?

  1. Hydropower

  2. Thermal power

  3. Nuclear power

  4. Solar power
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Nuclear power is the process of using nuclear fission to generate electricity. It is a non-renewable energy source because it relies on the use of uranium, which is a finite resource.

Multiple choice
