- B) Gravity pulls precipitation down to Earth's surface, completing the cycle.
- C) The sun's energy is responsible for causing gravity to act on water droplets.
- D) Without the sun, water would not be able to condense into clouds.
- E) Gravity helps in the formation of clouds by holding water vapor in place.
