What is the average humidity in the Sahara desert?
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, w…here plants grow well and people can live all year long. In 1922 a temperature of 136Â° F (57.8Â°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.  During the last glacial period, the Sahara was even bigger than it is today, extending south beyond its current boundaries.  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.  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.  By around 3400 BC, the monsoon retreated south to approximately where it is today,  leading to the gradual desertification of the Sahara.  The Sahara is now as dry as it was about 13,000 years ago.  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.  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.  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.  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 (MORE)
The Sahara covers the northern section of Africa , and spreads over almost all of the "top" of the continent. It is the largest hot desert in the world, as well as the second largest desert on earth after Antarctica. The Sahara covers all or part of Algeria, Chad, Egypt, Libya, Mali, Mauritania, Mo…rocco, Niger, Sudan, Tunisia and Western Sahara. . The word "Sahara" means "desert" in the Arabic language. The Sahara is one of the hottest places on earth. September, 1922, the temperature in the Sahara soared to 136 degrees F. At night the temperature can drop below freezing. . Land Forms . The Sahara Desert has many different landforms. Parts have sand dunes. A sand dune is a mountain of sand. Some dunes can be as high as 600 feet. These dunes are found in huge areas of shifting sand called ergs. Regs are another type of landform found in the desert. regs are broad plains covered with sand and gravel. Regs make up most of the Sahara. Hammadas also make up a large part of the Sahara. These are areas of flat, raised land that are also known as plateaus. There are volcanic mountains in the Sahara in the country of Chad. Emi Koussi, a peak in the Tibesti Mountains is 11, 204 feet high and the highest point in the desert. . Water . The rain in the Sahara is less than 10 inches a year. People cannot survive without water. There are few lakes. Most of these anyway are saltwater lakes. People cannot drink from them. Lake Chad is the only freshwater lake in the desert. Rivers once ran through the Sahara. We know this because dried up riverbeds, called wadis, still exist. When it does rain in the desert, these wadis fill up with water and become active rivers for a short time. . Sandstorms are very common in the desert. Brown clouds of sand cover the sky as wind blows sand everywhere. . Sometimes you can find gazelles and antelope in sand dunes of the Sahara. Mostly though, you will finds, birds, snakes, lizards, gerbils, and small foxes in the dunes. . if u mean shahra desert , its in nothern africa..The Sahara covers parts of several African nations including Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Sudan and Tunisia. The Sahara Desert is located northern Africa. It extends from the Mauritania on the west coast of Africa to Egyptin the east, and from the Mediterranean coast (approximately 32degrees North Latitude) in the north to roughly 14 degrees NorthLatitude. It is about 9,400,000 square kilometres in extent. the Sahara Desert is located in Africa and runs through 11 othercountries. Including -Algeria -Chad -Egypt -Libya -Mali -Mauritania -Morocco -Niger -W. Sahara -Sudan -Tunisa In other words, the Sahara covers nearly all of northern Africa. The Saharad desert is in Africa The Sahara desert is in northern Africa, where it occupies parts of Algeria, Chad, Egypt, Eritrea, Libya, Mali, Mauritania, Niger, Tunisia, and Western Sahara. The Sahara is the world's largest desert excluding the polarregions. It is located in Northern Africa and stretches fromMauritania to Egypt and Sudan. The Sahara Desert covers Northern Africa from 17Â° 30' W to 51Â° 30' E, and from N37Â° 21' in Tunisia to about S 2Â°in Somalia. So, Africa. (MORE)
the average rainfall is 3 inches I had to use his for my science project so I hope that I helped you out.
The Sahara Desert in northern Africa is the largest hot desert inthe world at 9.65 million sq km. The Gobi Desert in China andMongolia is the 3rd largest hot desert in the world at 1.3 millionsq km.
Yes, the Sahara is the world's hottest desert. It is also theworld's largest hot desert and has some of the most brutal climateon the planet.
A desert is any place that receives less than 250 mm of precipitation a year. Desert types can be arranged in a two by five matrix. On one axis - Hot deserts: Very hot in the day, potentially cold at night Cold deserts: Potentially warm during the day, very cold at night On the other ax…is - Sand desert: essentially a sand sea Stony desert: cobble and gravel surfaces Rock desert: bare rock surfaces kept clear of sand or gravel by wind Plateau desert: rocky plateaux and buttes with deeply eroded wadis Mountain desert: bare and arid rock peaks On this matrix the Sahara would be a "hot sand desert" Points of Interest in The Sahara: The Richat Structureis, a conspicuous "bull's-eye" in the flat and uninteresting of the desert, is found in Mauritania near Ouadane. It has a diameter of almost 30 miles (50 km) (MORE)
According to paleoclimate models and scientific discoveries in theregion, the desert dried out through a gradual climate change wellover five thousand years ago. It was once much like the Sahelregion 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 theconditions. 10 000 years ago the Sahara had grass and other vegetation withplenty of wild animals and the climate was moderate. Approximately4000 BC there was a dramatic change in climate and the rainfallbecame less. This lack of rain caused the rivers and lakes to dryup which led to soil erosion. The Sahara is the largest desert inthe world with an area of 9,1 million square kilometers. (MORE)
Easily the forest.. The forest is most definetly more humid because there would be a lot of rain for the trees to grow. The rain that is unused and still remains in the soil is what will evaporate and make it humid. Deserts usually are not near anything (bodies of water) so they would be much more …dry and a lot less humid. (MORE)
No, actually. The Antarctic Desert is the largest desert, thoughsome geographers disagree. A desert is determined by its annualprecipitation, and Antarctica is definitely a dry cold area. Deserts are normally divided into "cold" and "hot" deserts. The Sahara is the largest hot desert and Antarctic…a the largestcold desert The Sahara Desert is the largest hot desert on Earth, but the largest desert overall is the Antarctic. (MORE)
No it is predominantly inland, although some of the desert area dorun along the coast
No it is a dry desert, however, certain coastal portions mayhave high humidiy and be slightly "tropical", however, they do nothave a tropical climate
It is desert due to lack of water, lack of farmable land, the type of flora and fauna that live there, climate, and vast amounts of sand. It gets very hot in the day and cold at night. It has sandstorms that are very severe.
Both Antarctica and the Atacama are drier that the Sahara Desert.Neither of which receives any appreciable precipitation.

The Sahara Desert is the largest hot desert, The largest desert is actually Antarctica . No. The Sahara is the largest hot desert covering 3.6 millionsquare miles, a bit larger than the Australian Outback, but rankssecond in size to the Antarctic Desert which is the largest desertin the world… (and the largest cold desert), covering 5.5million square miles. true No. The world's largest desert is Antarctica 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, or almost 5.5 million square miles. However, when most people think of deserts the implied thought is that they are sand based not ice based. It is also not known as the Antarctica Desert because it is not referred to as such in the text books. The Sahara is the largest hot desert. It is in northern Africa and occupies over a quarter of Africa, covering 9.1 million square kilometres, or 3.5 million square miles. It is generally more recognised as a desert because its rate of evaporation exceeds the rate of precipitation, whereas the Antarctic has a very low evaporation rate. The Sahara is the largest hot desert in the world covering 3.6 milllion square miles, but Antarictica covers 5.5 million square miles and has less than 10 inches of precipitation per year. therefore Antarctica is the largest desert in the world. No, Antarctica is the largest desert in the world. The Sahara isthe largest hot desert and the second largest desert. (MORE)
The Sharah Desert is mainly inland, although at points the desert does touch the coastline of Africa
The Sahara is hot at daytime and cold at night. Gobi desert is cold during the day and night.
The Atacama desert is not very humid at all. The Atacama desert is the driest place on the earth. Some locations, however, receive a marine fog known locally as the camanchaca , that provides sufficient moisture for hypolithic algae, lichens and even some cacti to grow. Some animals, particularly i…nsects, are able to harvest this moisture which allows them to survive in this harsh climate. However, there are some areas in the Atacama which receive little rainfall each year but maintain a high humidity due to the proximity of the Pacific Ocean. Arica, for example, receives less than 1 mm of precipitation per year but has an average humidity of nearly 75%. (MORE)
Ha-ha, not easy, but if you knew where your relative position was the best thing would probably to head towards the coast (which ever was the closest). The thing that you wouldn't want to do is travel south, this would only take you deeper in to hostile terrain with few signs of civilization.
The Sahara Desert is hotter than the Atacama Desert, it's larger than the Atacama Desert and it has more life, but the Atacama Desert is much drier. The Atacama Desert is the driest place on Earth, with an average of less than a millimetre of the rain.
Texas on a warm day would have more absolute humidity, but theSahara Desert on a cold night would have more relative humidity.
No . The Sahara Desert is the largest hot desert in the worldbut it is located in Africa. The Gobi Desert is the largest desertin Asia. Clarification: Actually, the Arabian Desert is the largest desert in Asia. TheGobi is the second largest.
The wind speed in the Sahara Desert varies significantly. However,It is famous for its wind, which often causes sand or dust storms.
No, the desert is not humid, that is why deserts don't get any or much rain.
There are two reasons I can think of: It's the biggest and it's relatively close to Europe.
The Sahara desert covers most of Northern Africa and the Arabic word for desert is Sahara.So the translation is actually desert desert.Wow that's a lot of sand.
The Kalahari Desert. Also there is Saudi Arabia which has a desertin it, and is east of the Sahara Desert. The Namib Desert issouthwest of the Sahara.
i don't know about night, but during the day the average temperature is about 86 degrees Fahrenheit, but on extremely hot days it can exceed 122 degrees Fahrenheit.
Plants adapt to these harsh conditions in may ways, for instance: . Longer roots to reach the water . Some have the ability to only live during times of less aridity . They all have thick external 'skin' to prevent the suns rays from with drawing too much water. . They often have spikes (to stop… predators from eating them.) (MORE)
When it is raining or foggy, the humidity can reach 100% but suchevents are rare.
Yes, the dew retains on the grass and the bushes leafs and in some desert animals skin.
very lil cuz theres no trees or plants for transpiration, no waterfor evaporation. the air is very dry thus humidity level is less. .
people effect the landscape by peeing in the sand and leaving rubbish and wate behind
There is no such thing as the "Savanna Desert." The savanna is agrassland that receives more rain than the desert. It is a separatebiome.
It is the largest "hot" desert in the world and second in sizeafter the Antarctic Desert, which is the worlds largest "cold"desert
Yes and no. As the temperature drops, the relative humidity rises.There is no more moisture in the air than during the day, however.Cool air can hold less moisture than warm air so the capacity ofthe air to hold water decreases.
That depends upon the specific desert and season of the year. Indeserts of the American southwest, the humidity may drop to lessthan 10 percent in the dry winter but may be 50-60 percent (ormore) during the summer rainy season.
Yes, they are the same. However, there is no need to add the word'desert' as Sahara means desert in Arabic.
Generally, no. However, the humidity in a desert can rise touncomfortable levels during the rainy season. As I write this fromthe Chihuahuan Desert the relative humidity is 79% and dew point is66 degrees. It is the monsoon season and the humidity isapproaching that of a tropical rainforest.
Yes the Sahara has sand seas, although sand deserts only accountfor 1/8th of the total area, the balance is rock and scree
No, the Sahara Desert is in Norrth Africa and the KalahariDesert is in Southern Africa
The average rainfall for the Sahara Desert as a whole is less than 5 inches per year (12.7 centimetres). The driest areas receive less than 2 centimetres or rain and the wettest areas get up to 10 centimetres or just under 4 inches of rainfall. It does not rain often and when it does it is usually a… torrential downpour. (MORE)
Hot, humid desert conditions are an anomaly and would only occur during therainy season. Deserts are usually quite dry and have a lowhumidity.
no.. there are other deserts like the Kalahari and Namib There are others, but I don't know any.
During most of the year the humidity runs below 20 percent, sometimes in single digits. During the summer monsoon the humidity can get considerably higher, however.
They've been isolated in that desert for so long. An isolated population can develop traits unique to a single region over time (on an evolutionary scale; a very long time).
The Sahel is not a desert. It is a distinct biome, a grassland, bordering the southern Sahara.
With sufficient water and food a person could survive indefinitely.Without water, just 2-3 days in the summer months.
This is because the saharians that live there 300years ago foundout the ancient greece mytholegy of physics so they decided toexplore the mainlands of the sahara desert and found minerals androcks and gust that was sahara and many did not come back alive sothey called the sahara desert the sahara de…sert.
