Mars is a planet with about 1/3 the surface of the earth. So it has about the same amount of land as earth has dry land. Mars has a gravity of 0.38g, earth has 1g. At 0.38g human beings probably live with no side effect like bone shrinking. Plants don't need any gravity and therefore feel perfectly comfortable at such a gravity. Mars' day, unlike all other planets' day, is comparable in length with earths' day. At the equator, the day is 24.5 hours long, on earth, the day is About 24 hours long. This is no problem for agriculture; the day-night rhythm is neither too short nor too long. This is one of Mars' big advantages compared with the moon.
Mars is also called the red planet because of its colour (which is red). The Martian soil (or Martian "regolith") has big amounts of rust (Fe2O3), which gives it the red colour. The abundance of rust is an advantage for future colonies which, if they desire to be independent from Earth and able to grow quickly, will need vast amounts of iron in form of steel. The iron can be gained easily from the rust in the martian soil.
(This might help a little bit)

"The atmosphere has lots of carbon dioxide. The ground seems to be the same kinds of minerals as the Earth has, with lots of silicates (silicon and oxygen and other stuff mixed in) and also a dash of iron oxides to give it that reddish color. Mars does seem to be somewhat lower in water than the Earth, probably because its original water got decomposed into oxygen and hydrogen, and the hydrogen escaped because it was so light."

It is one of the four rocky planets that are close to the sun, it is probably made of the same material as the other three , rock, minerals, and perhaps there was water at some time, etc.
