Yes - for half the year.
decrease in density and become water vapor
About 97% of Earths water is saltwater.
yes mars does have ice on its poles it also has water
The hydrosphere encompasses all of Earth's water.
Yes water cycle use up earths supply. Water is evaporated from earth's surface.
poles
because they are different parts of the earths hemispheres.

no. but most of earths fresh water is.
because it gets cold on the way.
All fresh water is stored in the ice shelves of the north and south poles.
earths tilt bring the hemishere closer to the suns direct rays were the sun can warm up the water.
Energy is needed to turn water into water vapour. This energy is released when the water vapour condenses back into liquid water. The source of this energy is the Sun - the Earths Hydrosphere takes the heat energy from the sunlight near the equator (which is warm) and distributes it towards the poles which receive less solar energy and are therefore colder.
Spin, water & land mass distribution, plus mountains.
The heat transfers through the entire ocean, since its technically one big global ocean.
Only about 1.7% of the world's total water is trapped in glaciers and ice caps, but about 68.7% of fresh water on Earth is frozen in them.
