There is no water on Mars because the planet is too cold to support water. Liquid isn't stable on the planet's surface but scientists have discovered that at one time, water was plentiful.
Water has been found on the surface of Mars. There are traces of oxygen, which is also a component of water, in the Martian atmosphere.
Because water ice has been found at the Martian poles. Most of the martian ice is carbon dioxide frost, not water. We have not detected any surface water as such there yet, though it appears Mars had water eons ago.
Not by the Martian gravity at any rate. The gravity on the surface of Mars is weaker than on Mercury.
The Martian surface has a thin atmosphere lacking sufficient oxygen for respiration and shielding from harmful solar radiation. Extreme temperatures, low atmospheric pressure, and scarce liquid water also make it unlikely for living organisms to survive on Mars without specialized equipment and protection.
No hardware sent to Mars has ever been returned to Earth, and nothing that's landed on the Martian surface has ever been launched from it.
Yes there is water on the moon
Water is evaporated from any surface.
no Not on the surface; some speculate that there may be frozen water beneath the surface.
What is the composition of the Martian atmosphere? Have you observed any signs of life on Mars? How do you sustain life on a planet with harsh conditions? Are there any resources on Mars that could be valuable to Earth?
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.
Water evaporates from any surface that it comes into contact with, including oceans, lakes, rivers, and even the surface of the skin. Evaporation occurs when the water molecules gain enough energy to escape into the air as water vapor.
Surface water is any water on the Earth's surface, such as in rivers, lakes, streams, and oceans. It includes water that flows or collects on the ground, as opposed to groundwater which is found underground.
