you would need a space suit....
The Core of Mars http:/en.wikipedia.org/wiki/Mars#Geology
if you are think sand would be a layer yes mars is covered with red sand
Mars is thick to earth
On Mars, there is a thick layer of red clouds, filled with nitric acid. you probably couldnt see the sun through the clouds. but if there was a time with no clouds, it would look almost identical to the way we see it on Earth. Slightly smaller, since it Mars is farther away from the sun than Earth, but it would still be yellow and it would hurt you eyes to look at it.
Mars is thin
No there is no ozone layer on mars. It is because of no proper oxygen there.
People would still need to wear a pressure suit, because the air pressure on Mars is far too low to support human life. Also, the average temperature on Mars is -63° C (-81° F). And people would need to keep themselves shielded from the sun, because Mars does not have a magnetic field or an ozone layer, which protect Earth from most harmful solar radiation.
The earth has a very thin layer of life-sustaining gasses (known as the atmosphere) surrounding it, mars does not.
The other person who answered this said Mars. This could be true on Mars's north and south pole, but its not entirely covered in ice. Ceres, the dwarf planet in the asteroid belt, and Europa, a jovian moon, may possess the qualities you included in your questions.
No mars doesn't have an ozone layer. It is because it doesn't have oxygen which can form ozone.
very warm clothing
Mars has no ozone layer. It has no atmosphere.
