I got some evidence for you guys--- My mom's friend said that Mars is covered with volcanoes, and after all, it is the "red planet", right? And what exactly do volcanoes produce? LAVA, ASH, ETC. Maybe the volcanoes very frequently errupted, thus leaving the ground a reddish color? Hmmmm...

Refferring to GeoDude's comment, You are NOT allowed to say that! DELETE CYBER BULLYING!
PS He said "WOW, ur all a bunch of effin nerdz!" Personnly, I would never say that.

I'm pretty sure the red color comes from rust. Mars has a surface rich in Iron oxide. Some scientist have hypothesized that the rusting occurred the early years of Mars when there would have been water to speed up the oxidation process. Also when ever lava and ash cools it's rarely red. It turns various shades of black and gray.

But it may be possible that the volcanoes and ash had something to do with the oxidation process and might be interesting to look into.

Ever seen a red volcano on earth? What color are they? Hawaii is all black and Mauna Loa is incidentally the same kind of Volcano as Olympus Mons on Mars. So the fact that Mars is red has nothing to do with volcanism. Instead the red color of Mars is because of iron oxides in the soil. Same reason the deserts of Australia and alot of Africa is red.

The fact that Mars has such a thin atmosphere is proof that Mars is geologically dead. No volcanoes are replenishing the gasses that are venting into space. Also you can see impact craters on the slopes of Olympus Mons. Those might have happened millions of years ago and if Olympus Mons were even a little alive those craters would have been erased long ago.

The Tharsis Bulge
One of the most prominent structures on Mars are shield volcanos. The Tharsis volcanos are easily recognizable even from a global view (Figure 6.1) . Tharsis is a region on Mars that consists of 12 large volcanos and many smaller ones (Figure 6.2) . This photo shows the four most prominent volcanos on the Tharsis region. The largest volcano in this region and on Mars is the Olympus Mons (Figure 6.3). It is a circular structure about 550 km in diameter (This single volcano would span across the entire Hawaiian island chain). It rises about 25 km from the surrounding plain. Such a vertical relief is greater than the distance from the top of the Himalayas to the bottom of the Mariana Trench, which is only about 22 km.

Dearest friend Ayumi:

The reddish color has been confirmed to have come from rust or oxidized iron by Spirit, Opportunity and Sojourner, the present Martian robotic probes.

Much of the color of lava is black or charcoal gray, depending on age.

Mars is tectonically dead. The largest (extinct) volcano in the solar system is on Mars, and its name is Olympus Mons. The "red" is from iron oxide (hemetite) in the soil. Your theory needs to be discarded.

i dont think there are active volcanoes on mars anymore. The reddish soil colour is due to high contents of iron oxide(rust)
