uhhh i rarely use powerpoinnt i suck at it XD



n uhh u dont hav to write exactly the same sentences as wikipedia... or how the hell do they expect u to do this??? u just dont hav to say that u used wiki 



Liquid water cannot exist on the surface of Mars with its present low atmospheric pressure, except at the lowest elevations for short periods[20][21] but water ice is in no short supply, with two polar ice caps made largely of ice.[22] In March 2007, NASA announced that the volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 11 metres.[23] Additionally, an ice permafrost mantle stretches down from the pole to latitudes of about 60°.[22]







Much larger quantities of water are thought to be trapped underneath Mars's thick cryosphere, only to be released when the crust is cracked through volcanic action.[clarify] The largest such release of liquid water is thought to have occurred when the Valles Marineris formed early in Mars's history, enough water being released to form the massive outflow channels. A smaller but more recent event of the same kind may have occurred when the Cerberus Fossae chasm opened about 5 million years ago, leaving a supposed sea of frozen ice still visible today on the Elysium Planitia centered at Cerberus Palus.[24] However, the morphology of this region is more consistent with the ponding of lava flows causing a superficial similarity to ice flows.[25] These lava flows probably draped the terrain established by earlier catastrophic floods of Athabasca Valles.[26] Significantly rough surface texture at decimeter (dm) scales, thermal inertia comparable to that of the Gusev plains, and hydrovolcanic cones are consistent with the lava flow hypothesis.[26] Furthermore, the stoichiometric mass fraction of H2O in this area to tens of centimeter depths is only ~4%,[27] easily attributable to hydrated minerals[28] and inconsistent with the presence of near-surface ice.







More recently the high resolution Mars Orbiter Camera on the Mars Global Surveyor has taken pictures which give much more detail about the history of liquid water on the surface of Mars. Despite the many giant flood channels and associated tree-like network of tributaries found on Mars there are no smaller scale structures that would indicate the origin of the flood waters. It has been suggested that weathering processes have denuded these, indicating the river valleys are old features. Higher resolution observations from spacecraft like Mars Global Surveyor also revealed at least a few hundred features along crater and canyon walls that appear similar to terrestrial seepage gullies. The gullies tend to be in the highlands of the southern hemisphere and to face the Equator; all are poleward of 30° latitude.[29] The researchers found no partially degraded (i.e. weathered) gullies and no superimposed impact craters, indicating that these are very young features.







In a particularly striking example (see image) two photographs, taken six years apart, show a gully on Mars with what appears to be new deposits of sediment. Michael Meyer, the lead scientist for NASA's Mars Exploration Program, argues that only the flow of material with a high liquid water content could produce such a debris pattern and colouring. Whether the water results from precipitation, underground or another source remains an open question.[30] However, alternative scenarios have been suggested, including the possibility of the deposits being caused by carbon dioxide frost or by the movement of dust on the Martian surface.[31][32]







Further evidence that liquid water once existed on the surface of Mars comes from the detection of specific minerals such as hematite and goethite, both of which sometimes form in the presence of water.[33]







Nevertheless, some of the evidence believed to indicate ancient water basins and flows has been negated by higher resolution studies taken at resolution about
