Mars has evidence of minerals that could indicate the presence of past water, but its surface is not muddy like Earth's. The soil on Mars is more like fine grains of sand or dust rather than rich, organic mud.
Excellent question, and perhaps someday we'll learn that. We do know that large volcanoes do form on Earth, but on Earth the forces of wind and water can erode the mountains and wear them down. On Mars, there is very little atmosphere, and very little water, so there's not much weathering.
Phobos has little if any atmosphere; like Mars, we would assume that if any oxygen was present, it could only be measured in parts per million.
Well, it does not- since no human has ever been to Mars. However, if you COULD go, it would be very dry, cold, little oxygen, and less gravity than Earth. Do not expect sunlight to be as strong- you are further from the sun. And it is very hard to get pizza delivered there.
Mars is a rocky planet with very little atmosphere.
Not very. Mars is a little red dot in the eastern sky just before dawn. It will be a little bigger in January, 2010.
There is little to no weathering on Mars due to the very small amount of atmosphere Mars has. Although there is evidence that there may have been weathering there in the past.
Mars has roughly 30% the surface area of earth. All of that is dry ground. We have only found(very little) ice on mars.
No, the atmosphere on Mars is made up mostly of carbon dioxide with very little oxygen. It is not breathable for humans.
There is very little water on Mars, but some can be found frozen at its North Pole.
With life support, perhaps. Mars is much colder than Earth, has much less atmospheric pressure, and very little oxygen.
Science have tried to find life on Mars. As of yet, 2010, this search have provided no evidence of life. It can not yet be dismissed, but there is very little chance of this.
Neither Venus nor Mars have appreciable amounts of water. Venus is shrouded in dense, poisonous clouds at very high temperatures; Mars has very little atmosphere.
Yes, because Mars has a very thin atmosphere. If it had a thicker atmosphere (similar to Earth), most of the meteors would burn up. Since it has a thin atmosphere, most meteors strike the surface. Also there is very little erosion on Mars, so when a meteor hits Mars, the craters lasts for a very long time.
Yes. Because there's very little water in the Martian atmosphere grains of sand or dust do not bond and so get blown about very easily. sand storms on Mars can engulf the entire planet.
No life is known to exist there. It is too cold, too dry, and there is very little atmosphere.
