The highest recorded temperature was 58 ºC (136.4 ºF), in Libya in 1922. In some areas, the summer temperature regularly exceeds 50ºC during the day, only to fall to near freezing 0ºC at night.
Clarification:
Scientists have thrown out the 1922 temperature reading as it was taken improperly by untrained technicians.
People have been traveling for thousands of years. Organized travel for leisure and cultural exchange became common during the Roman Empire, with the development of roads, inns, and organized tours. However, travel for trade and exploration has been happening since ancient times.
Archaeologists found the cave paintings in the Sahara Desert by exploring and surveying the region extensively. The paintings were often discovered in sheltered rock shelters or caves, which preserved them from the elements. They were uncovered through a combination of fieldwork, satellite imagery, and the guidance of local communities.
The "Sahara Desert" is a broad expanse of northern Africa, roughly from about 10 degrees north latitude to about 23 degrees north latitude. There are a number of smaller "regional" areas that are often lumped together by the term "Sahara".
The precise amount of sunlight would vary by date and by latitude, but let's use 20N and December 21. That spot gives us about 10 hours 55 minutes of sunlight for the shortest day of the year. That close to the equator, there won't be a large difference in the duration of sunlight during the course of a year. At the equator, of course, the length of the days and nights are pretty much equal throughout the year.
The US Naval Observatory's web site has a calculator that can generate the precise time of sunrise and sunset for any location and date. See the link below to generate your own calculations for the precise location and date you're interested in.
I would expect to find camels in a Sahara caravan.
Extinct means the animals no longer exist so there can be no extinct animals in the Sahara. If there were, they would not be extinct.
I asked a similar question of Dr. Christopher S. Swezey in 2001:
Hi - I recently came across your letter to Science in the 10/8/99
issue and thought you might be able to answer a question I have had
since visiting the Sahara in 1985: how deep is the sand at its
deepest? Or how deep at the greatest depth that has been sampled or
imaged? Are your thermoluminscence data from drilling core samples?
Thanks in advance for satisfying my idle curiosity.

Here's the answer he gave me:
Much of the Sahara is characterized by bare rock, and the sand in the
Sahara tends to occur in discrete groups (usually topographic basins).
Large areas covered by sand are called sand seas or "ergs." Within ergs,
however, the amount of sand cover is variable. Dunes take on different
shapes, as a function of wind characteristics and the amount of sand
available. Barchan dunes (small crescentic dunes) form where the wind is
unidirectional and where there is not much sand available. The interdune
areas associated with barchan dunes consist of bare rock or some other
non-sandy substrate. In contrast, star dunes form where the winds are
multidirectional and where there is a lot of sand available.
I am most familiar with the Grand Erg Oriental (Great Eastern Sand Sea) of
Tunisia and Algeria. This erg is characterized by barchan dunes and other
small linear dunes in the north, larger dunes with various linear and
grid-like shapes further south, and star dunes at the extreme southeastern
part of the erg. The tallest star dunes of this erg are 320 m high, and
the interdune areas around the star dunes are filled with sand (Star dunes
in most other regions of the Sahara are not as tall as the star dunes of
the Grand Erg Oriental, so I assume that the sand cover is less thick in
these other regions). I am not certain how thick the sand would be if you
drilled a well in the middle of an interdune area among the Erg Oriental
star dunes (maybe 150 m, maximum?). I do know that the dunes of the Erg
Oriental rest on top of sandstones of Miocene age (~5-23 million years
old), that these sandstones are exposed in the interdune areas to the
north. Some oil companies have drilled wells in the southern part of the
sand sea, but their targets are very deep and they rarely report the
thicknesses of the younger sediments near the surface.
My thermoluminescence dates from the Grand Erg Oriental were from small
outcrops on the northern margin of the erg, where wind-blown sand deposits
interfinger with lake and river deposits. I chose this area because it is
a basin that lies below sea level, and is still subsiding. I thought that
this might have the oldest record of wind-blown sediments in the Sahara. I
found out, however, that most of these sediments are relatively young
(<18,000 years old), and that these relatively young sediments rest
directly on top of much older Miocene sandstones. This pattern of
relatively young sediments (thousands of years old) resting on top of much
older sandstones (millions of years old) is consistent with what is
observed in most of the rest of the Sahara. If I were to go back to the
Sahara today and look for the oldest record of wind-blown sand, I would
probably look in the area of Lake Chad (another basin that is subsiding,
and filling up with sediments).
Anyway, that may be more information that you wanted. I did most of my
work in the Sahara when I was in graduate school (Univ. of Texas at Austin,
and Univ. Louis Pasteur in Strasbourg - France). When I wrote the letter
to Science, I was employed by British Petroleum in Texas, but about a year
and a half ago I quit BP and took a job with the U. S. Geological Survey.
I am currently working on putting together a story on the origin of the
Sahara Desert, and I am also working on various projects associated with
the Appalachians.
Thanks for contacting me, and let me know if you have any other questions.

The Sahara desert IS NOT hot all the time.Because the temperature in there always be changes.
Example : In the afternoon,the Sahara desert is very hot.But,in the night,the temperature in the Sahara desert changes be colder.
Sahara desert doesn't have much of the agriculture.This happens because the climatic conditions in Sahara doesn't support the growth for plants.Eventhough plants like cactus and date palm tree grow here.These plants have long roots to absorb water from the deep soil and they have spine like leaves or sometimes no leaves at all for preventing transpiration(loosing water)through leaves.
No, they cannot live in a savanna desert because there is no such place. There are deserts and there are savannas and each is a distinct biome. But a roadrunner could live in a savanna as a savanna is a grassland with few trees.
The Western Desert is 262,000 square miles. It is made up of canyons, dunes, and oases. The Western Desert is located in Egypt.
Cacti are native to the Americas and are not found naturally in the Sahara Desert.
i dont know you tell me okay.
The Sahara desert covers a vast area so there are variations between regions. The Sahara desert is the hottest place with average temperatures over 86f/30c. Daily variants have been recorded as being as extreme as being between -5c/31f to over 100f/37.5c
The highest temp in the Sahara is 136 degrees and the lowest temp in the Sahara is 86 degrees
Since you need a grade you need to do it. We don't help you cheat and that is what you are asking us to do. The only way you will learn is by using your brain, not mine.
There are 3 main religions of Africa: Islam, Christian and Traditional. However, Traditional is mostly in the south; Islam and Christianity are the main Saharan religions.

The war in the deserts of Egypt & Libya were important for two reasons.
Firstly, Britain stood alone and desparately needed to safeguard the Suez Canal which was her short-cut to the East.
Secondly, as far as Britain was concerned, it was the only game in town. France had fallen, Britain had narrowly avoided invasion from the Germans. Britain was not strong enough to take the fight back to Europe and all she had left was (still) the most powerful navy in the world and a foothold in North Africa.
To begin with Britain was fighting the Italians who were trying to expand their Empire. They made short work of them and soon pushed them back deep into Libya. Hitler then agreed to help Mussolini and sent Rommel with his Afrika Korps. This was a shock to the British who were thrown all the way back to a small railway halt called El Alamein where the 'impassable' Qattara Depression came close to the sea. There they held the Germans while both sides struggled to build up enough strength to break the impasse.
Eventually, General Montgomery leading the 8th Army, launched a devastating blow on Rommel which forced him back. Montgomery kept up his advantage and never allowed Rommel to re-group or counter-attack.
Soon afterwards the Americans landed in Vichy-French controlled Algeria in West Africa and between Montgomery in the East and Patton in the West slowly squeezed Rommel out of Africa altogether. From there combined British/American forces launched an invasion of Sicily and then Italy while the D-Day landings were being planned in England. The success of D-Day and the German troops held down in Southern Europe hastened the end of the Nazi regime.
Of major importance too was to block German attack routes to India and in particular the oil in the Caucasus
The African campaign was also important because I believe it was the first time that Germany had proven to be beatable. Rommel had an impeccable reputation and there was a myth about him that he was unbeatable. It is nteresting to note that Rommel was executed by Hitler for wanting to overthrow Hitler. Romel was given a state funeral so he could be honoured by the German people. The question comes to my mind as to whether the defeat was orchestrated in terms of wanting to make Hitler look bad so that people would turn against him and Romel could take over.
The language that is mostly spoken in The Sahara Desert is Arabic
Arabic is the main language spoken in the Sahara desert
Most speak Arabic.
what languages do they speak in the sahra desert
No one really knows. Not a lot of research has been done on the Sahara because it is so windy. Scientistscan't exactelyy study it untill the dust bowl is over. hope this helped fellow samaritons!
Most of those who live in countries covered by the Sahara Desert live in North Africa along or near the Mediterranean coastline
Most people in the Sahara desert live near the Nile River because it is one of the only reliable water sources.
The Yangtze River Dolphin (lipotes vexillifer) that is thought to have gone extinct this year but scientists believe that there may a handful left but they cannot confirn that there is even that many left, thay cant seem to locate them. If it is not the Yangtze River Dolphin, then it would be a speicies of rabbit called the Riverine rabbit (Bunolagus monticularis). Good question! It's a stumper.
