What is a desert? A desert is an area full of dry sand and poor vegetation. Occasionally there are desert plants and desert cactus. Lots of desert people go to the desert with their falcons for hunting. They hunt for rabbits, for Houbara, similar to a bustard, having long black and white feathers on each side of the neck. Lizards and coyotes live in the desert. There are one hump camels as well as two hump camels. Some are caged animals but usually they are wandering. Camels travel in groups.
What is a desert? Only 20% of deserts on Earth are covered in sand. The Arabian Desert in the Middle East is the second largest hot desert on Earth but is smaller than the Sahara. Deserts generally receive less than 40% of rain in a year. Hot deserts usually have high temperatures in the day and very cold temperatures at night. Deserts have very low humidity. Deserts often contain surprisingly, large mineral deposits.
Rattlesnakes Rattlesnakes – The rattlesnake is poisonous. This type of snake does not attack large animals unless he is frightened. It shakes the rattle on its tail as a warning. At night, the snake is quiet. It uses its forked tongue to help it sense when a small animal is nearby. When the snake glides silently forwards, it quickly strikes the animal. It puts its poisonous fangs into his prey and then it lets it go. The animal tries to run away, but it usually dies very quickly. The snake will then find the dead animal and swallows it whole.
lizards Australian lizards have a spiny skin to protect them from enemies. When the lizard is in danger, it puffs out its frill to frighten its attacker. A lizard is a dangerous animal it can hurt a person. People should not attack a lizard because it could hurt them badly.
Foxes The fennec fox has large ears which makes it hear well but also helps it to throw off heat. Its short desert coloured hair reflects heat in the day and keeps it at night.

Human affect Extremes of heat affect the humans severely. Humans cannot bear extremities of heat, as they can lose up to 3 litres of moisture in an hour and up to 12 litres in a day. This water has to be replaced otherwise the person will be dehydrated and die. Humans kidneys do not work in the same way as desert animals that keep urine to conserve water. In the absence of rainfall no food crops will grow, so humans will not find food to eat. People have to live in camps not houses and wear loose fitting clothes. These clothes absorbs the sweat as the air moves through it creating a cooling effect. As a result the person sweats less and this conserves water.
