There are probably several things Mercury has very little of, but compared to the other planets is has very little size/mass and very little distance from the sun.
There probably is no mud on Mars; mud would imply water, and Mars has very little water.
Mars has rocks and is very dusty. It has lots and LOTS of powerful winds. There is little or no water on Mars. Mars has no air so we chould not breath there. Earth is only mialdly windy and only has certain areas of dusty and rocky landscape.

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.
The primary reason Mars is so much colder than the Earth is that Mars receives less than half of the of the energy from the sun as Earth does. This is because Mars is further away from the sun than Earth is. Mars' atmosphere is over 90% CO2, but Mars' total atmosphere is only about 0.6% that of Earth. Meaning that Mars has very little atmosphere of any kind to speak of, and so its atmosphere provides only negligible insulation to the planet. The net result is a very cold planet with very low atmospheric pressure. From an Earthling's perspective, Mars is no more hospitable than the vacuum of space.

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.
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.
Some very tiny fraction of 1% of the mass of Mars is ice. We don't know how much there is, but at least a little water is known to be present near Mars' north pole.
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.
