Which of the following correctly describes where early earth's water came from?

a. rains from violent storms created oceans

b. ice on mountainous structures melted

c. collisions between earth and stars released water

d. carbon in earth's crust converted into water vapor that was then condensed

Orbit is represented by the blank space

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.

B. to increase the amount of antibiotics in the body
