Now let's talk about bad weather on Mars. Bad weather brings clouds and rain to the surface of the Earth.
Water covers 2/3 of the surface of the Earth. On Mars, there is not nearly as much water around. Because there is so little water in the atmosphere, that means that it is very hard to form clouds. And that means that it may never rain on Mars.
In the next few pages of this tour, we will take a look at the weather on Mars: clouds, storms, and winds.
