absorption of solar energy by continental land masses use of solar energy in the process of photosynthesis reflection of solar energy from polar snowcaps transformation of solar energy into auroras
I gave my students this multiple choice question: Which of the following best describes an interaction between Earth and solar energy that functions to warm up the planet?

Only one answer is correct among these 4 choices:
- absorption of solar energy by continental land masses
- use of solar energy in the process of photosynthesis
- reflection of solar energy from polar snowcaps
- transformation of solar energy into auroras

Could you tell me which one is correct?
