Resource summary
Hot Desert Climate
Location
Found 15-35° south of the equator.
Examples: Sahara (Africa) and Kalahari Deserts, Arizona, Australia and California.
Climate
Daytime temperatures are extremely high : 30-50°C
Temperature differences are between day and night not seasons.
At night the temperature can fall as low as 5°C.
Minimal Rainfall
As trade winds blow towards the equator they become warmer.
On shore winds shed their moisture as they blow over cold ocean currents.
Vegetation
Arid conditions have very little vegetation.
Cactus has deep roots which allows them to absorb any water sources. They also have waxy skin which minimises water loss through evaporation.
Date Palm has deep taproots to find moisture.
The Joshua Tree has juicy flesh which stores water.
Animals
Main animal is the camel which has adapted to the extreme conditions.
Camels have thick knee and foot pads to allow them to kneel and walk on sand.
They have humps on their backs to store water and fat.
Have thick lips to eat prickly plants.
They have long eyelashes and they are able to close their nostrils to prevent sand getting in.
Society
The deserts are very sparsely populated.
Usually home to some pastoral desert dwellers who herd cattle and goats.
Governments are restricted the freedom of these nomadic tribes.
Camels are replaced with motor vehicles.
Tribes are being moved to industrial areas.
