Mars has many interesting geological features on its surface.The volcanoes on Mars are now extinct, but they indicate a preceding period of significant Martian volcanism. Such volcanoes are called shield volcanoes, because they look like shields.

The surface features of Mars are that it has a rocky outer crust blanketed with a rust colored soil. Mars also has many valleys, plains, and volcanoes. In fact, Mars is home to the highest volcano in the Solar System! On its southern side Mars has many craters, making it very different from its northern side with valleys and plains. Even though it has valleys and plains Mars has no grass or water. They were actually formed by vol canoe's lava hardening for millions of years. Mars's Olympus Mons, is 3 times the height of Mount Everest on Earth! Mars also has a canyon that stretches across 1/4 of the planet, it's called Valles Marineris. And it is 10 times longer than the Grand Canyon!Mars also has craters like our moon in its south and channels were water might once have flown, these channels widen as they go further down. Some of these channel patterns also go around the craters.

The surface features on Mars are mainly made of rock.
