What causes temperature extremes in the desert?
Aaron AndersonDryness of the air.
Dry air does not produce clouds. Clouds reflect incoming solar radiation (albedo). So during the day there is no clouds reflecting the incoming solar radiation and it reaches the surface of the Earth, hence the warmth.
During the night the lack of cloud cover minimizes the greenhouse effect, meaning very little of the outgoing heat from the surface of the Earth is trapped. Therefore the temperature drops.
It is important to note that the largest desert in the world is Antarctica and it doesn't have extremes, it is just cold.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
