A layer of ice on the surface keeps the water temperature warmer than the air temperature.
Well first i just wanna say that life on mars has been discovered,not little green men but Bactria found on the surface and small traces of water have been found as well. some forms of life need little water to survive (like bacteria) but they still need water so yes there is water on mars the question is will we find it.
It can become a sedimentary rock over time because of weathering. sedimentary rocks are rocks that have been broken down over time by water and erosion. hope this helps.
