Sahara Desert

extreme heat, very little or no water

low temp. or too much rain

It snowed in 1979 for the first time on record. In 2012, it snowed again in the Algerian Sahara.

scientists estimate around 100 billion. just kidding, nobody has bothered to make an estimate because of the pointless nature of this question. If anyone asks you just say "a lot of it" and walk away.

west of the Nile River, south of the Mediteranean Sea

Yes, the Sahara is much larger than California.

Sahara: 9,400,000+ square km or 3,320,000+ square miles

California: 423,970 square km or 163,696 square miles

The Sahara desert is the size of the whole of the USA and produces sandstorms the size of the UK!

The Sahara desert is globally very sunny and even extremely sunny in the eastern part (desert part of Libya, Egypt and Sudan). The sunshine hours varies from 3,000 hours to 4,000 hours in the desert. The central, hyperarid part of the Sahara records more than 3,500 hours of sunlight annually everywhere. The days are generally cloudless, clear and sunny while the cloudy days (days with no sun) remain very rare in the region but we can't mention accurately the actual sunny days in the desert. The desert sun shines nearly every day and strongly (the sun is usually high in the sky) since the Sahara desert is located in the subtropics, near the tropics.

The Nile river and the atlantic are two of the major water sources for the Sahara desert region.

The largest desert in the world is Antarctica which is not in Africa. The largest desert in Africa is the Sahara.

lol no way you idiot its a desert

The Sharah does in fact have mountains, only 1/8 to 1/4 of the Sahara is sand

There are various ways that on can stop deserts from spreading. One of the best options is afforestation whereby trees are planted on bare ground.

Because plants won't grow without water - if plants once grew in the Sahara then there must have been water there.

No as Sahara temperatures plummet to below freezing temperatures at some points in the year

Ecology

Millipedes are detritivores, foraging for decaying organic material (in the desert, generally in sandy washes). They are nocturnal and prefer humid environments, often appearing on roads after soaking summer thunderstorms. They are good burrowers and spend most of their time underground. If disturbed, the millipede rolls into a coil. If further threatened, it exudes foul-tasting chemicals from openings along the sides of its body. These noxious substances are the millipede's only defense, since it doesn't bite.

Termites are important in the South Texas ecosystem, and caution should be used in interpreting and applying short term, narrowly focused experiments on termite removal. For one thing, desert termites, or rather their gut flora, are now known to fixatmospheric nitrogen (Schaefer and Whitford, 1981). Furthermore, they remove organic carbon from the surface, especially during drought, so that less of that resource is available to denitrifying bacteria near the soil surface when rains return. Termites also protect mesquite-fixed nitrogen from volatilization and/or leaching by moving it well underground where it is stored in termite biomass. In the short term, this nitrogen is not available to the shallow rooted grasses of the system (Parker et al., 1982) but in the long run it is, as the mating flights after rains put millions of termites into the food chain across the entire landscape (Schaefer and Whitford, 1981). Like shrub clumps, termites fix, accumulate, protect and slowly leak mineralized nitrogen into the system. We need to know much more about these and other desert detritivores (El-Ayouty et al., 1978: Crawford, 1979) before planning to remove or manipulate them.

Who are 'they'? Are they humans, animals, plants? Try to be specific.

The social custom of desert is marriage of children at small age and (ghugat pradha) in Hindi and in English both.

vultures do live in the desert becaus ethe can find very hot teperatures for food.

The Sahara is not even a river. It is the world's longest desert.

The primary land use in Mali is grazing/pastures. More than 25% of the land is used for this purpose with the rest distributed between a variety of other uses.

The mean temperature of the Sahara Desert is over 30 ºC (86 ºF).

The average summer temperature is 30 ºC (86 ºF); winter temperature 13 ºC (55 ºF), considered low for a desert but a fact, apparently. Some months have average temperatures of 40 ºC (104 ºF), often reaching the 50 ºC (122 ºF). Summer temperatures can show a daily range of more than 50 ºC - reaching that temperature during the day then plunging below freezing at night.

The highest recorded temperature was 58 ºC (136.4 ºF), in Libya.

The Sahara desert is quiet expansive, as such the "mean" temperature varies quite a bit, coastal areas of the desert being more temperate. Night temperatures (particularly during the winter months) can drop dramatically after sunset due to the lack cloud cover (as well as re-radiation); temperatures can drop to -5 ºC and some ares can even experience frost.

its just called travelind like any other thing using a car on camel in the desert

While the Sahara Desert is normally an inhospitable region, it lies north of the equator and as such does experience seasonal variations.

Most countries that lie within the region that covers the Sahara simply refer to it as the wet or dry season, there is very little variance with respect to autumn and spring.

During the "dry" months there is no rain and the temperatures during the day are scolding, even the night temperatures can be well above 30 degrees Celsius.

In the "wet" months intermittent rain (mostly torrential) can fall, on average half the Sahara receives 20mm of rain per year and the other half less than 100mm of rain. Temperatures during the cooler months can drop to 20 degrees Celsius with night time temperatures sometimes down to 0 Celsius.

There are also recorded occurrences of snow at high altitudes during this time.

No, Rhinos need savanna grass to eat and the Sahara desert does not have enough for them. However before the Sahara region became a desert (10's of thousands of years ago), there is evidence that Rhinos were indigenous to the area.

The Sahara Desert is found in the Northern region of Africa.
