I've never been to a desert, but I think it would be cool to visit one. Have you?
Yeah its a barren landscape with little rain and harsh living conditions
Yes, I imagine it would be very harsh to live there. Dry and hot!
About a third of the land mass is desert
Wow, that certainly is a lot. There isn't much plant life, is there?
there are deserts in the polar regions called cold deserts
Yes, I recall a bit about them. There are much cooler at night?
deserts are classified by the amount of rain they get
That makes sense, as if they don't get much, there can't be much vegetation or growth. Plus, I'm sure it makes the landscape very dry and arid!
When it does rain in the desert they are prone to flash floods
