why is mars red?

Answer 1

A quick search for "chemical composition of the martian surface" yielded the following web site:
http://sci.esa.int/science-e/www/object/index.cfm?fobjectid=31029

Amongst the observations contained therein is that "Mars, like blood, derives its red colour from oxidised iron. Haemoglobin carries oxygen bound to iron in the blood, whereas dust, soil and rock rich in oxidised iron give Mars its reddish hue."

Have fun!

Answer 2

Is Mars Really Red

Answer 3

Mars is red because it's surface contains a great deal of iron based or iron oxide based minerals, like many rocks here on Earth. The difference is iron oxide minerals dominate the surface of Mars, whereas on Earth they are only a few out of some 3,000 different minerals that can be found at or near the surface of Earth.

Answer 4

Mars is the fourth planet from the Sun in the Solar System. The planet is named after Mars, the Roman god of war. It is also referred to as the "Red Planet" because of its reddish appearance as seen from Earth.

A terrestrial planet with a thin atmosphere, Mars has surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts and polar ice caps of Earth. It is the site of Olympus Mons, the highest known mountain in the solar system, and of Valles Marineris, the largest canyon. In addition to its geographical features, Mars’ rotational period and seasonal cycles are likewise similar to those of Earth.

Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Martian Trojan asteroid. Mars can be seen from Earth with the naked eye. Its apparent magnitude reaches −2.9[1], a brightness surpassed only by Venus, the Moon, and the Sun, though most of the time Jupiter will appear brighter to the naked eye than Mars.

Mars has half the radius of Earth and only one-tenth the mass, being less dense, but its surface area is only slightly less than the total area of Earth's dry land.[1] While Mars is larger and more massive than Mercury, Mercury has a higher density. This results in a slightly stronger gravitational force at Mercury's surface. The red-orange appearance of the Martian surface is caused by iron(III) oxide, more commonly known as hematite, or rust.

Answer 5

Mars is NOT red. It is braun colored, the planet looks only red when we look at it from Earth, also wrong satelite pictures has to be the reason many ppl think this planet is red the planet has a red looking thing though from earth, and this is a very rare thing, if we see it from earth, this planet looks like its "the planet of war, blood, madness etc.. which it is from earth but not from the galaxy perspective, you think about that very closely and you must try to understand how this planet afflict our daily lives. every professional astronomer could tell you that this planet is in reality not red at all.

Answer 6

Mars is known as the red planet because of the color of its top layer of soil. This soil is rich in iron and has combined with oxygen to become a rusty red color. From Mars's surface, you would see a rusty-red landscape and a pink sky as winds blow its fine dust into its atmosphere.

Answer 7

The material which makes up the surface of Mars is very rich in ferrous or iron based minerals. As you know when iron is exposed to oxygen (one of the components of the martian atmosphere) ferrous oxide is produced otherwise known as rust. Since rust has a reddish colour, this is what makes the surface of Mars appear red.

Answer 8

Astronomers call Mars the Red planet because of its colour.Its surface is reddish-orange.This colour comes from the rust-like iron minerals in the surface rocks and soil.

Answer 9

Mars appears to be reddish in the sky to us because that is the primary color that the rocks and dust on the surface of Mars reflect. Martian rocks vary in color, but on the whole, the reddish color is what appears to our eyes on Earth when all the reflected light blends together.
Jupiter appears to be white to the eye, but if you've seen some of the pictures taken by telescopes and space probes, you've seen that it is made of a myriad of colors that are constantly changing, just like Jupiter's clouds. That myriad of colors, when blended together, appears to be white when it reaches our eyes.
Uranus appears to be green and Neptune bluish because of the gasses in their atmospheres and their temperatures. Venus looks bright white due to it's 100% cloud cover that actually looks mostly white to me. Mercury and Saturn appear slightly yellowish to me, Mercury due to its rocky surface and Saturn, again, due to its cloudtops.

Good Question! You get a star from me.

Answer 10

because the fibers and metals cover up Marses surface and over a period of time the surface got rusty and rust is red ,so that's why mars is red
