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.
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.
No mars doesn't have an ozone layer. It is because it doesn't have oxygen which can form ozone.
Mars has no ozone layer. It has no atmosphere.
Mars lacks a significant ozone layer like Earth due to its thin atmosphere. The atmosphere on Mars is composed mainly of carbon dioxide, with trace amounts of other gases. This means that Mars does not have sufficient ozone to form a protective layer like the one found on Earth.
There is no life on Mars (Barsoom) because there is no Ozone Layer there.
Mars does not have an ozone. It is because of absence of atmosphere.
Thin.
