It certainly does, but it's in the form of ice.
Yes, water is present on Mars in the form of ice. There are polar ice caps on Mars that consist of water ice and observations suggest the presence of subsurface water ice as well. Additionally, liquid water may exist temporarily in some regions on the surface.
There is only very small amounts of water in a gas form in the atmosphere and there has been found that there is water in the ice caps on Mars. There is no liquid water on Mars. But ancient Mars is believed to have as much water as Earth does today, in liquid form.
yes and an advanced life form called gigantuspithicus
Yes. Mars use to have water like Earth's. When Mars's core cooled dramatically, the water on Mars froze.
Ice
Ice
No. For two reasons: # The temperature on the Martian surface is less than 0 Celsius and thus any water (to form a swamp) would be in the form of ice and therefore solid. # The atmospheric pressure on Mars is so low that water can not exist at the surface. If you place a lump of ice on Mars and heated it, it would go straight form solid Ice to water vapor. Thus this again means that there can be no water on the surface of mars with which to form a wet swamp. However, having said this please understand that there is H2O on Mars in the form of ICE and water vapor - we do not know how much H2O there is at the moment and we believe that there was quite allot of liquid water on Mars' surface in the ancient past.
Because there is no water on Mars. It is frozen solid in the form of ice, if it even is water. There are traces it has been there once on it's surface and inner layers, but we haven't found any yet
I do not think that Mars has any known water at all.
mars has water in for of ice in it
solid object
There is water in the form of ice under the "top-soil" of mars and when ever it gets uncovered it evaporates fairly quickly. so there is also water vapor, what happens to that vapor I don't know. Currently we don't know if there is liquid water on mars, we haven't found any yet, and just the fact that there is water-ice on mars is really miraculous
