Moving to the desert might be kind of cool.
Maybe! The barren landscape and little precipitation might be tough! Would you build a house or live in a tent?
Yeah, it would definitely be tough! A house would make it more comfortable for sure. 
Correct! Also if your out at night there it might be cold! This is why its called a polar desert or a "cold desert".
Oh, wow! What kind of temperature does it get down to?
I'm not sure specifically, but cold isn't the only weather issue! Dust storms are common when particles of sand are picked up and thrown around!
Oh, that sounds dangerous!
Correct! And these wind-blown sand grains can abrade surfaces! I think something like a garden would be impossible in the desert.
Yeah! Where do people get their food from?
I'm not sure, but it's very little anyways! The conditions are hostile for both plants and animals@
