An area that features this climate usually experiences less than 250 mm (10 inches) per year of precipitation and in some years may experience no precipitation at all. In some instances, an area may experience more than 250 mm of precipitation annually, but is considered a desert climate because the region loses more water via evapotranspiration than falls as precipitation (Tucson, Arizona and Alice Springs, Northern Territory are examples of this). To determine whether a location has an arid climate, the precipitation threshold must first be determined. Hot desert climates Regions with hot desert climates Hot desert climates are typically found under the subtropical ridge where there is largely unbroken sunshine for the whole year due to the stable descending air and high pressure. Hot desert climates feature hot, typically exceptionally hot, periods of the year. Examples Cold desert climates Regions with cold desert climates Mild desert climates References

Information on Desert ClimatesDeserts represent one-fifth (20%) of the land surface of the world. The majority of deserts are in the Arabian Peninsula, Australia, The Americas, North and South Africa, India and Pakistan. The largest desert is the Sahara, in North Africa, and is about 3,500,000 square miles. Deserts are characterized by extreme heat and dryness, very hot in the daytime and chilly or even cold at night. The average temperature is 100 degrees during the day and below 50 degrees at night. The wettest desert does not get more than 10 inches of rain a year. A variety of plant and animal species live there, thanks to their power to adapt to the harsh environment. Animals like rattlesnakes and scorpions spend most of the day underground but come out at night to eat and hunt. Spade foot toads spend 9 months of the year underground. Deserts often get their names like "Death Valley" or "The place from where there is no return" because of their extreme conditions.
It gets cold at night in the desert.Interesting factsDesert BiomesIn this report you will learn about Hot and Dry Deserts and Cold Deserts. I hope you enjoy! A Hot and Dry Desert is, as you can tell from the name, hot and dry. Most Hot and Dry Deserts don't have very many plants. They do have some low down plants though. The only animals they have that can survive have the ability to burrow under ground. A cold desert is a desert that has snow in the winter instead of just dropping a few degrees in temperature like they would in a Hot and Dry Desert. Deserts cover about one fifth of the Earth's land surface. Hot and Dry Deserts temperature ranges from 20 to 25° C. The precipitation in Hot and Dry Deserts and the precipitation in Cold Deserts is different. Hot and Dry Deserts are warm throughout the fall and spring seasons and very hot during the summer. the winters usually have very little if any rainfall. Hot and Dry Deserts vegetation is very rare. Cold Desert's plants are scattered. Stetson N. 2000 bibliography:
Difference Between Tundra and DesertTundras and deserts are both fairly large areas which see very little rain throughout most of the year. Due to this, these areas are extremely difficult to live on, and can be near uninhabitable at times. A tundra is an extremely cold area which is usually frozen over; deserts, on the other hand, are exactly the opposite, as they are excessively hot and sandy. While temperatures in tundras are shockingly low, high temperatures are a defining characteristic of deserts (particularly during the day time). Thus, while these regions share some common features (e.g. the amount of rain they get), they are completely different from one another in regards to their severe climate – in fact, they can be said to be polar opposites. Instructions 1 TundraA tundra is the region situated near the polar ice caps, with a cold, dry, windy, and icy climate.
DesertDesert Climate Animals Plants Health Concerns The desert is dry, barren, hot, and silent. Climate There are two main types of desert in the world-the hot desert and the semi-desert. Deserts are formed when something gets in the way of rain clouds. Mountains also play a roll in forming deserts. Animals When most people think of the desert, they think of camels, snakes and lizards as being the only animals that live in the desert. Here in the Oregon desert, you can find bobcats and chipmunks and woodchucks among the sycamores. Plants Plant life in the desert is scarce, but there are more plants living here than you would expect. Plants in the desert are forced to make many adaptions in order to survive in this dry, hot land. The Desert plants are of great importance to the animals of the desert. Health concerns There are many health concerns in the desert. Snake bites are another concern in the desert. Sunburn in the desert is prevented by putting on sunscreen. Biome Index
Fact1Blue Planet Biomes - World BiomesWhat is a Biome? A biome is a large geographical area of distinctive plant and animal groups, which are adapted to that particular environment. The climate and geography of a region determines what type of biome can exist in that region. Major biomes include deserts, forests, grasslands, tundra, and several types of aquatic environments. Each biome consists of many ecosystems whose communities have adapted to the small differences in climate and the environment inside the biome. All living things are closely related to their environment. The earth includes a huge variety of living things, from complex plants and animals to very simple, one-celled organisms.Facts 5Fact2DesertsFar from being barren wastelands, deserts are biologically rich habitats with a vast array of animals and plants that have adapted to the harsh conditions there. Some deserts are among the planet's last remaining areas of total wilderness. Yet more than one billion people, one-sixth of the Earth's population, actually live in desert regions. Deserts cover more than one fifth of the Earth's land, and they are found on every continent. And despite the common conceptions of deserts as dry and hot, there are cold deserts as well. Desert animals have adapted ways to help them keep cool and use less water. Desert plants may have to go without fresh water for years at a time. Some of the world's semi-arid regions are turning into desert at an alarming rate. Global warming also threatens to change the ecology of desert.
Grevy's Zebra, Equus grevyiby Jay Sharp The Grévy’s zebra belongs to the Equidae family, which includes thehorses and donkeys as well as the plains and mountain zebras. The Grévy’s zebra – the first of the zebras to evolve – staked its primary range out of sparse plains and scrublands in the Horn of Africa. Ithas developed finely tuned adaptations to its arid home. Characteristics The Grévy’s, roughly 25 to 35 percent larger than the plains and mountain species, is one of the odd-toed ungulates—the large grazing and browsing mammals that have an odd number of weight-bearing toes, or hoofs (actually modified toenails), on each foot. Range and Diet The Grévy’s zebra ranges across the hot and arid plains and scrublands of northeastern Kenya and southeastern Ethiopia. By contrast, the plains zebra grazes and browses on the more lush plains and grasslands that run from the Horn of Africa southward along the eastern side of the continent, migrating as much as 700 miles to maintain ready access to water.
