i don't understand why people are finding it so hard to understand the point being made here..
As per our 'complete' understanding, earth is/was the only planet with water in the ENTIRE universe, so as per this hypothesis, water erosion is
There apparently is no atmosphere on Mars, so WIND erosion?? how?
and for it reach an almost spherical shape indicates a long time of natural erosion...
Thank you for your threads Arken..
not many may not agree with them all, but it certainly peeks your interest to know that we really know nothing about the place we hold in this
Please do some reading before you make statements like these that are very untrue.
First, Mars does indeed have an atmosphere (how else do you think the skycrane worked?). It's thin, about the same pressure as if you were 30 miles
up in the air here on Earth, but it most certainly does have an atmosphere still (and was much thicker in the past), and even has weather on it.
Earth is the only body in our solar system that has liquid water on it's SURFACE. Let's get that straight right now.
There a many other bodies in our solar system that have water. Either frozen solid, both on their surfaces or under them. Some even have liquid water
under their surfaces.
Mars has show with out a doubt, that it has had large amounts of liquid water in it's past, before it's atmosphere became too thin to support liquid
water on it's surface.
With as much water and more atmosphere in the past, there is no reason why rocks would not have been weathered and eroded then. Much more than now.
However, even now, erosion and weathering does still happen on Mars.
Where would the rocks that have been weathered and eroded long ago disappear to? They would still be there. They would not disappear.
