What is a Desert?
Deserts are regions that receive less than 250 millimeters (about 10 inches) of rain per year. Despite their harsh conditions, they are home to an amazing diversity of life forms.
Desert Adaptations
Animals like camels store fat in their humps to survive long durations without food and water, while plants like cacti have spines and thick skins to reduce water loss.
Sand Dunes and Mirage
The ever-shifting sand dunes can tower up to 180 meters (590 feet) high. Mirage, an optical illusion in deserts, tricks the eye into seeing water at ground level.
