Martian polar ice caps

Okay kiddo, let me explain about the polar ice caps on Mars. You know how sometimes it's really cold where we live and we need a jacket to stay warm? Well, it's really cold on Mars all the time, even colder than the coldest place on Earth, which is Antarctica.

So cold that even the air on Mars is mostly made up of carbon dioxide, which is what we exhale when we breathe. And when it gets really cold, the carbon dioxide and other gases in the air will freeze and turn into ice. That's how the polar ice caps on Mars form.

The polar ice caps on Mars are located near the North and South poles, just like how Earth has polar ice caps. They are huge and can be seen from space, and scientists think that they are mostly made up of frozen carbon dioxide, which is also called dry ice.

But there might be some water ice mixed in there too, because scientists have seen signs of water on Mars in other places. These ice caps change in size with the seasons on Mars, just like how the snow melts and the flowers grow in the spring and summer here on Earth.

So there you have it, Mars has polar ice caps that are made up of mostly frozen carbon dioxide and might have some water ice too. And just like on Earth, these ice caps change in size with the seasons.
