M: Welcome back, I didn’t see you in math class on Friday.
W: I wasn’t here on Friday. My geology class went on a field trip to look at some of the different rock formations here in California. Our last stop was Death Valley. In fact, We camped there last night.
M: Death Valley? But that’s desert. Wasn’t it much too hot for camping?
W: No, not really. It gets hot during the day, but it cools off very quickly at night. There is no moisture in the air to hold the heat after the sun goes down. If it were humid, it would stay hot all night.
M: Well, did you enjoy the trip?
W: It was fascinating. ’The desert is nicer than you might think. Since there is so little vegetation growing, it’s very easy to see different rock layers, folds and such, and the natural colors of rocks are wonderful. The rocks have made brilliant colors, blues, pinks and greens. You really should go to see it sometime.
