The Desert consists of hot, dry, sandy regions that receive less than 25 centimeters of rain per year. They often are home to sandstorms, sand dunes, and a variety of plants and animals that don't require constant water consumption for survival. (Allaby)


The most common type of sand dune through out the desert is known as the crescentic. These crescent like mounds of sand are wider in size than longer. Under winds are made from this type of dune that blow in only one direction. (Allaby)

Sand storms, that commonly occur through out the desert are violent winds that pick up the sand around it. The sand and dust at first forms a thin layer and then transforms into a thick blanket blocking off all sunlight, roads, plants, oases, or almost anything. Sand storms have greater effects at ground level then higher up, and can last for hours or sometimes even days, and can cause dehydration and even suffocation. (Allaby)


Temperatures in the desert vary from extreme highs to extremes lows. These temperature changes can vary depending on what month it is, and also what time of the day it is. The hottest time of day in the desert is at noon. Most animals come out during the night because it is too hot during the day for animals to be out trying to gather food.

In the desert there are many different species animals. Snakes and lizards are commonly seen in the Desert. Also found in the desert are mammals called caracal's. To find out more about these animals- click here...

Plants in a desert hold a very important role for the wildlife that inhabits it. They provide shelter and in some cases provide a water source to the inhabiters. One of the most largest plants is the Saguaro Cactus which is home to many birds along with their nests. This plant is almost like a "tree" because of how tall it is and of the birds that live in it. This plant lives in North America around Arizona L.A. and Mexico. Other plants that live in a desert are shrubs, Brittle Brush, and Prickly Pear. Prickly Pears are a shell-shaped cacti that is covered with needles and is located in Canada, United States, Mexico and the Americas. It must carefully be peeled in order to consume the fruit inside it. There are new species of plants that have adapted to deserts such as peas and sunflowers.

The desert is not a great place to be if you want to find water next to you everyday. Rain is not a common thing to see when you are in the desert. When it rains it usually results in a violent experience. A desert receives approximately 25 centimeters of water every year. The rain that drops is short lived because by the next day it will start to evaporate. So this means the animals must drink the water before it is gone.

The desert holds an abundant supply of sunlight. It evaporates any still water in it quickly, which is why water is so scarce throughout the desert.
