At any moment, the atmosphere contains enough water vapor to cover the entire surface of the Earth (land and ocean) with one inch of rain. As air is cooled, some of this becomes water droplets. When the water droplets within the clouds become heavy enough, they can fall as either rain, sleet, snow, or even hail, depending on conditions. What is the name of this part of the water cycle?
A. Condensation

B. Evaporation

C. Precipitation

D. Sublimation

All equations of the form ax^{2}+bx+c=0 can be solved using the quadratic formula: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.

A. Condensation

Explanation:

Condensation is the change of the physical state of matter from the gas phase into the liquid phase, and is the reverse of vaporization.
