If you can answer these that would be great :)

Why is the sky blue?
n the air?
is water wet?
Why don't birds get electrocuted when they land on an electric wire?
Why is the sun the only star that can be seen during the daytime?

It's cell theory. easy name i would think.

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.
