Recreate the water cycle in the comfort of your own home: Fill a glass with warm water. Fill a second glass with cold water, and add a few ice cubes.
A. What does the outside of the glass with ice cubes feel like?
B. What caused this change?
C. Why didn't the same thing happen to the glass filled with warm water?

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
