* Volcanoes: Mars definitely has volcanoes! In fact, it has the largest volcano in the solar system, Olympus Mons. It's a shield volcano, similar to the volcanoes in Hawaii, but much, much larger. Mars also has a number of other extinct volcanoes, indicating that it was once volcanically active.

* Storms: Mars experiences dust storms, sometimes very large ones. These storms can engulf the entire planet and last for months. While not technically the same as the thunderstorms we experience on Earth, they are powerful and can create dramatic changes in the Martian atmosphere.

Here's some additional information:

* Olympus Mons: This giant volcano is about three times the height of Mount Everest and has a base wider than the entire state of Arizona.

* Dust Storms: Martian dust storms are driven by solar energy, which heats the atmosphere and creates winds. These storms can be so powerful that they can block sunlight and even interfere with robotic missions on the planet.
