Deserts
are known to be hot, dry biomes. But there are also "cold" deserts.
In these deserts the nights are very cold, especially in the winter. As there
is little rainfall, few types of plants exist. Some vegetation includes cactus
and the Joshua tree. Animals in the desert include marmots, prairie dogs and
several varieties of snakes and lizards. Many of these animals live underground
for much of the day. They adapt to the heat by hiding under rocks when the sun
is out.
