The desert biome is one of the most interesting biomes on earth. An area of land is considered a desert when it produces less than 10 inches of rainfall throughout the year. There are many different types of deserts in the world, with a very diverse group of plants and animals. It has temperatures that are generally hot during the day, and cold at night. A desert is a region so arid due to little rainfall that it supports only sparse and widely spaced vegetation or no vegetation at all.
Sand as far as the eye can see and very little rainfall occurs in this region. About 2500 B.C., the climate of the Sahara changed. Africa was once a fertile plain but where the Sahara lies was once a fertile plain capable of harvesting foods nearly anytime of year due to the warm weather. But it slowly dried up. As the land became parched, the desert spread.
They both make a good sprint for their prey although leopards tend to stalk their prey a little more. They eat medium sized prey which is relatively smaller than prey of other big cats eat. The females are solitary in both species though cheetah males make a coalition, male leopards are also solitary. Leopards are the strongest big cat there is, they can drag their prey, which is sometimes bigger than the leopard is, up into trees for safekeeping and safe eating from other big predators. They are also the fastest climbers of all the big cats.
Temperature The Tundra suffers a very harsh climate. Because of this fact most of the area remains barren save for a few shrubs and lichens. It's winters last from 8-10 months and the summers are cool and short. Also due to the fact that much of it's territory is located within the northern pole a lot of the Tundra receives alternating 6 month periods of light and dark. This is also the reason why the Tundra receives cold weather; at it's degree of latitude the suns rays end up hitting the region obliquely, thus causing less solar heat.
One of the most commonly referred and greatest deserts is The Sahara located in North Africa stretching over an astounding 9 million square kilometers. Some tropical portions of the desert biome can experience annual temperatures of 30 degrees Celsius which is very hot. The cold desert regions in North America, Central Asia, and South America can have an average temperature of 15 degrees Celsius with a difference of as much as 35 degrees Celsius between July and January. The deserts in high latitudes can experience freezing temperatures in the winter. Deserts are very unique severe moisture deficit which sets this apart from other biomes, and gives it its unique characteristic.
Adaptations of Mammals to Arid Australian Environments Abstract High temperatures and low rainfall characterize much of Australia. It is hard to believe that animals can survive in arid conditions, much less prosper. Yet there is a whole range of mammals, among other life forms, that do. These animals survive because they have adaptations that allow them to live in the hot, dry conditions. The function of the adaptations is to balance thermoregulation with water gain and loss.
But people are able to survive in the desert, getting water from springs and oases. Where there is no water, there are no people, and these arid regions between water sources are only visited by the occasionalt migrating herder. There are some regions in the Middle East, however, that receive some rain during the year, sometimes more than 50 inches, compared to the desert's 4 inch average. These areas are found mostly in NE Iran and Afghanistan, though the rivers that drain these highlands provide water for the valleys beneath. Rivers that flow from a humid climate region, through the desert, to the sea are called exotic rivers.
The effect is the opposite of a heat mirage though. Here, you can see that the mountain looks to be up-side down and mushroom shaped. In the winter in the far north, the temperatures can get real low! This was the coldest temperature during the winter of '03-'04. The extreme cold allowed me to have a little fun and also caused a few problems.
Crossing the Taklamakan is very dangerous and deadly because there is no water on this desert (Hruschka). This very sandy desert has extremely low temperatures in the winter. Sometimes the temperature reaches to negative twenty degrees celsius ("Gobitec"). The Gobi and Taklamakan deserts both isolate and protect China. As described, China's geography had a positive and a negative impact on China.
It is not just your average "Oh no, I'm sweating" kind of hot, but unbelievably, unbearably hot. The mountains, however, are temperate, cool, and comfortable. The weather in the mountains stays relatively steady and moderate. Hurricanes have a strange tendency to hover around the beach; whereas, they seem to be almost repulsed by the mountains. The mountains have a certain feeling of climatic calmness that the beach most definitely lacks.
