Mars Water something?

Question

Why is there wet soil or something on ,ars was it once a flourishing planet that had life and plants and stuff like that

Answer 1

"...was it once a flourishing planet that had life and plants and stuff like that..."

The verdict is still out on whether or not Mars has ever had life. It's very possible that some very primitive forms of life may have evolved there once, like bacteria and other microbes, but doubtful that life ever moved much beyond such crude forms. So far we've not found any evidence that complex forms of life, like plants and animals, existed on the martian surface. Mars lost most of its atmosphere billions of years ago, and without that it's hard for higher life forms to exist. Once manned missions get there though we might well be in for some major surprises.

"...Why is there wet soil or something on ,ars..."
Our unmanned probes to Mars have found lots of evidence that water continues to flow intermittently on the martian surface. Scientists speculate that the current source for this water lies just below the surface in the form of permafrost (..that's stuff kind of like frozen mud..). Occasionally it thaws into a more liquid form and finds its way to the surface, especially on the slopes of craters.

Answer 2

The problem words are "liquid water".
For life as we know it to exists, you must have LIQUID water.
There might have been some liquid water in the past on Mars, when there was an atmosphere and some atmospheric pressure.
Now, the atmospheric pressure on Mars is so small that LIQUID water cannot exist on the surface. It might exist underground, in the form of ice of pressurised water. Released from the high pressure underground to the surface, the water would immediately "sublime" from ice to vapour, that is would not stay liquid.
If something liquid exists on Mars, it could be CO2.
But NOT H2O. (simple physics...)
As others have said, maybe it had some lower form of life in the distant past. But not today.
Nevertheless, finding some bacterial form of life would be a giant step forward for us to understand the evolution of life itself.

Answer 3

Life most likely did exist on Mars. Our Earth will probably look similar in a couple billion years or so.

Answer 4

IM NOT AN " EX-SPIRT " THATS MY JOKE FOR TODAY. ANYWAY MARS WATER MOST LIKELY FLOWS IN THE SUN DRENCHED AREAS. BUT CAN FLOW AND APPEAR IN COLD AREAS THUS HAVING BEEN HEATED AT GREAT DEPTHS THEN SEEPING THRU TO SUPER COLD AREAS THUS MAKING ICE MARKINGS. ONE OF THE MOST AMAZING FEATURES OF MARS IS CALLED VALLES MARINERES APPROX TEN TIMES LONGER,FIVE TIMES DEEPER,AND 20 TIMES WIDER THAN THE GRAND CANYON IN THE U.S.A.

Answer 5

scientest have pridicted from the clue they r getting on mars through robot (spirit) , ya there r the possibitlites of the life but in past & it may have extinct.

Answer 6

man they don't know. they do have new evidence that proves there was some kinds of ecosystem there... but for how long and how complex... its a mystery

there was running water... and where there is water there is life
