Mars

Mars is the forth planet from the sun, and is reddish. It's surface is covered with rusty-coloured rock and dust.

Mars has a giant canyon that makes Earth's Grand canyon look tiny. The canyon on Mars is longer than the distance across the US.

Mars also has a very large volcano that is 3 times as big as Mt Everest. It is called Olympus Mons. Mars has a thin atmosphere surrounding and is not enough air for a human to breath.
