Desert, Hot and ColdBy: Jos, Denomie and Julia

Location

Hot Deserts are found around the latitudes of 30 degrees north and south on every continent.

Cold Deserts are located above 30 degrees north and below 30 degrees south in dry areas.

Climate

In hot deserts, the days average at about 38

degrees and the nights at about 7 degrees. The annual rain fall is less

then 25cm.

In cold deserts rain is also minimal at less then 25 cm yearly. Summer days very from 21 degrees to 26 degrees and winter

between -2 and 4 degrees

PlantsPlants in the hot dessert have thick stems and leaves to store water and their roots extend for meters underground to collect water, such as the spiny cacti. They also store chemicals in their stems to protect them.Plants in the cold deserts don’t usually grow more than a meter tall, like the plants in the hot desert their roots extend for meters underground such as sagebrush.

Animals

In the hot desert the reptiles have thick skin to preserve water. Scorpions and spade-foot toads bury underground to keep cool.

Foxes, coyotes, jack rabbits and pocket mice all live in the cold desert, they burrow to escape the cold.

Physical Features

In hot deserts the soils are salty because minerals don’t wash away. Sometimes there is a lot of rain in a short period of time.

Most precipitation falls as snow, it mostly rains in the spring. The soil is also salty like the hot desert.
