About the same (in all 3 phases : solid, liquid, & gas).

about 75%
It will pull water down, just as it will pull anything else down, and just as on Earth.
The total amount of water on Earth has remained relatively constant over the past 100 years. However, changes in the distribution of water due to activities like urbanization and climate change may have altered the availability of freshwater in some regions.
Ground water accounts for approximately .61% of the earth's water today.
The water cycle
The earth is in what astronomers call the 'Goldylocks Zone': Just the right distance from our sun that liquid water can exist.

When the Earth first formed, there was an abundant amount of deuterium in the atmosphere. Today, most of the deuterium has fused into helium and because of that, there is little deuterium left.
True. The water on Earth is believed to be the same water that was present when the Earth was first formed, as water is a finite resource that cycles through the environment in a process called the water cycle.
I'd have to say about 1000000 quarts.
