I think that one time Mars was coverd in water then and over the years that water formed channels and what not. Then the water slowly started disappeering. The reamining water evaporated then suddenly there was a super eruption and that water formed with the volcanic ash. from then on mountains were made out of tuff! and earthquakes!

CAN MY THEORY BE TRUE?

You had me right up to your super eruption.

First, by the evidence of water channels and with the formations of globules it is clear that at one time water flowed on Mars, although I doubt if it covered the entire surface as you implied. More like it was some percentage as with the Earth.

Mars has a much lighter gravity than the Earth and the Earth is losing some atmosphere every day. As the air and moisture that it carries raises some of it, a very small percentage, is lost to space. Since our Earth's core is molten and radioactive there is enough energy to keep it hot for millions of years and through volcanoes it releases enough new chemical compounds that our system can run for a long time. Of course if too many trees are cut and if too much lands surface is paved over then we will face a drop in our oxygen levels and another rise in our CO2 problems.

Since Mars is smaller then it takes less time for this atmosphere evaporation to run its course. This is the most probably reason for the lack of water on the surface of Mars.

As for your theory of the volcanic ash mixing with the water, I am sure it holds true to a limited extend. Yes ash would absorb the water, but scientists think that much more of it has sunk deep under the surface. If you theory was true then probes like the two Mars Explorer or the earlier small one could have found that evidence. The fact that didn't means little. We haven't tested the soil that extensively yet.

Ash has different characteristics than sand, it is much lighter, and it can get into joints better than sand can since it is much finer. We have known about the sand dust storms on Mars for a very long time and we have noticed how it kills our probes. In fact the eventual fate of Spirit and Opportunity will be a slow death due to battery failure as the sand collects on and etches the solar panels. The fact that they have exceeded their original expected lifespan by 90% is amazing.

Olympus Mons is the largest volcano in the solar system, it is a huge broad mountain and it must have spouted out fountains of ash. That ash would have combined with your water if both were around and active on the surface at the same time, but since then thousands of years of sand has been deposited on top of it.

You theory brings up a valid point, but one that would require a deep drill to test, or a lucky asteroid hit. To expose the ash were a probe could see it. However, it is much more likely that the water is frozen as ice under the frozen CO2 at the North Pole, or it is deep underground or it just evaporated into space. Only a small amount save a few thousand gallons would be tied up with a mixture of ash.

Your theory has an interesting base on the Earth; we have had huge problems with water mixing with volcanic ash creating flowing rivers of mud called lahars (http://en.wikipedia.org/wiki/Lahar). I saw an interview with a Mexican who fell prey to a lahar after an eruption. He was buried in 4’ of mud which had started to harden, it is was thick that he couldn’t break himself free.

We don’t see evidence of lahars on Mars, but I am sure that part of the slopes of Olympus Mons has them. There is the best place to check to prove your theory. But, even if your theory of lahars is proved then I still think the atmosphere evaporation was responsible for a lot more loss of water than ash. I also think that there are large water pockets deep under the surface of Mars. I hope I am right because then it could be possible to build a self sustaining colony on Mars.

It is a possibility but you missed on big thing.
A Electro Magnetic Field!
Mars's volcanoes is what powered it's magnetic field therefore protecting it from solar flares and other harmfull rays. Water formed with 1 Hydrogen and 2 oxygen molocules. With the EM Field protecting the planet life could form with water and plants as well. When the volcanoes died so did the EM field. Which left mars vulnerable to solar flares and other rays which destroyed mars. With no EM field water, plants and life couldn't exist. So it is possible for your theory to be correct but. The River Valleys and Valles Marineris would be formed from weathering and erosion.
Hope I helped some.
