What is the nickname for the Sahara desert?
There is no such thing as the 'Savanna Desert.' The savanna is a grassland and a distinct biome of its own. The savanna south of the Sahara is called the Sahel.
Why is the Sahara desert an example of an extreme environment?
The Sahara desert is hot because this hot desert is located in the subtropical regions called the horse latitudes. The hot deserts located in subtropical latitudes are formed by the atmospheric circulation, more precisely the Hadley Cell, characterized by a dry descending, sinking air towards the ground. When the air descends, it warms up considerably and forms a hot weather year-round. This subtropical zone of sinking air is called the subtropical ridge.

What is the purpose of the Sahara Desert?
it is used for peoples passion with there camels and trading.
What are the negative effects of the Sahara desert?
Negative - it is really hot in the day and really cold at night.
Positive - it is beatiful
Yes. Some deserts are actually classified as cold deserts.
The Antarctic is the world's largest desert, since a desert is defined as an area receiving less than 250 mm or 10 inches of precipitation per year. The Antarctic desert covers 13.9 million square kilometres.
Another large desert that is not hot is the Karakum Desert in Turkmenistan. It lies between the Caspian Sea and the Amu Darya, and covers an area of about 310,800 sq km.
The Gobi Desert, which stretches across 1.3 million sq km in China and Mongolia (Asia), is also classified as a cold desert.
Even hot deserts can get very cold at night in Winter.
The Sahara is the world's largest hot desert, almost as large as Europe and North America and located in Northern Africa.It covers most part of the following countries, Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan and Tunisia.
Picture of Sahara desert on the map?
Northern Africa, it's one of the largest deserts in the world, next to Antarctica. The Sahara encompasses large portions of Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan and Tunisia.
How did the Sahara Desert become a desert?
According to paleoclimate models and scientific discoveries in the region, the desert dried out through a gradual climate change well over five thousand years ago. It was once much like the Sahel region to the south, with dry grassland and seasonal lakes.
Because the land is arid and has a very little amount of rain fall, making it extreme for survival.
This means that animals and plants must adapt to cope with the conditions.
10 000 years ago the Sahara had grass and other vegetation with plenty of wild animals and the climate was moderate. Approximately 4000 BC there was a dramatic change in climate and the rainfall became less. This lack of rain caused the rivers and lakes to dry up which led to soil erosion. The Sahara is the largest desert in the world with an area of 9,1 million square kilometers.
What are the wind patterns of the Sahara Desert?
momsoons Actually: SCIROCO are the desert winds. (Prounounced: sh-ur-AH-ko)
How have humans and animals adapted to life in Sahara desert and Antarctica?
they have adapted in life by drinking water and to be safe
What is the other name of desert?
There is no such desert as the Great Australian Desert. There are a number of deserts in that country that comprise the collective deserts of Australia that are sometimes referred to as 'The Outback.'
What type of a desert is the Sahara?
The Sahara Desert is a hot, dry area covering most of North Africa.
Because there is practically no rainfall, few plants can grow there and those that do are specialized for arid conditions. In some parts there are no plants at all. Occasional wet areas fed by underground springs support oases, where plants grow well and people can live all year long.
In 1922 a temperature of 136° F (57.8°C) was recorded, making the Sahara the hottest desert in the world.
It is also the biggest hot desert in the world. However, it is the second biggest desert, as Antarctica is the biggest desert (but a cold desert).
Some parts of the Sahara are sandy with giant dunes, while other areas are gravel plains, rock plateaus and mountains (only 3/8th of the Sahara Desert is sand).
it is an expanse of sand where almost nothing lives only a few organisms are capable of surviving there .Some of the sand dunes can reach 180 metres (590 ft in in height
The climate of the Sahara has undergone enormous variation between wet and dry over the last few hundred thousand years.[11] During the last glacial period, the Sahara was even bigger than it is today, extending south beyond its current boundaries.[12] The end of the glacial period brought more rain to the Sahara, from about 8000 BC to 6000 BC, perhaps because of low pressure areas over the collapsing ice sheets to the north.[13]
Once the ice sheets were gone, northern Sahara dried out. In the southern Sahara though, the drying trend was soon counteracted by the monsoon, which brought rain further north than it does today. The monsoon season is caused by heating of air over the land during summer. The hot air rises and pulls in cool, wet air from the ocean, which causes rain. Thus, though it seems counterintuitive, the Sahara was wetter when it received more insulation in the summer. This was caused by a stronger tilt in Earth's axis of orbit than today, and perihelion occurred at the end of July around 7000 BC.[14]
By around 3400 BC, the monsoon retreated south to approximately where it is today,[15] leading to the gradual desertification of the Sahara.[16] The Sahara is now as dry as it was about 13,000 years ago.[11] These conditions are responsible for what has been called the Sahara pump theory.
The Sahara has one of the harshest climates in the world. The prevailing north-easterly wind often causes sand storms and dust devils.[17] When this wind reaches the Mediterranean, it is known as sirocco and often reaches hurricane speeds in North Africa and southern Europe. Half of the Sahara receives less than 20 mm (0.79 in) of rain per year, and the rest receives up to 100 mm (3.9 in) per year.[18] The rainfall happens very rarely, but when it does it is usually torrential when it occurs after long dry periods.
The southern boundary of the Sahara, as measured by rainfall, was observed to both advance and retreat between 1980 and 1990. As a result of drought in the Sahel, the southern boundary moved south 130 kilometres (81 mi) overall during that period.[19]
Recent signals indicate that the Sahara and surrounding regions are greening because of increased rainfall. Satellite imaging shows extensive re greening of the Sahel between 1982 and 2002, and in both Eastern and Western Sahara a more than 20 year long trend of increased grazing areas and flourishing trees and shrubs has been observed

Who discovered the Sahara Desert?
Dr. Newton Jibunoh is the present-day explorer who has crossed the Sahara alone -- twice. He is a Nigerian who has devoted his life to the prevention of desertification.
But the answer to the question who reached the Sahara first, is completely lost in the sands of time. Actually the Sahara was an area of grasslands and lakes (already inhabited by people) until it became a desert because of climate change as recently as about 4000 BC. And today the desert is still expanding -- a somber fact that people such a dr. Jibunoh would want to whole world to know. Scientists are warning us that millions of African people could be forced to move elsewhere in the near future because of this desertification.
