What are the best ways to see the Sahara Desert?
The best way would be to join an international tour or safari group. However, considering the instability of much of Africa and all the violence, much of it directed against westerners, a person might want to think twice about traveling in this region.
Why is it cold in the sahara desert at night?
The desert generally has low humidity and little cloud cover to hold in the heat at night. Therefore, the heat easily radiates off into space once the sun sets.
The low humidity and lack of cloud cover allow most of the day's heat to radiate back into space, even from rocks that are scorchingly hot in the daytime sun. The dry air is not a good storage medium for heat, compared to humid air or large bodies of water. In places like the mountains of Colorado, most of the precipitation is snow, and the air cannot absorb and hold much humidity. On an average day, the difference in temperature can vary as much as 40 to 60 degrees. The high can be 95°F and the low 40°F.
Also the lack of cloud cover in the desert allows heat to escape a lot easier into the atmosphere.
the sand cant hold the heat.
it reflects the heat by the day, which is quite a lot and dosent hold anything for the night.
The reason the desert is cold at night is because after the heat from the sun wears away, the desert is just a flat, dark plain. There's lots of wind that chills the desert at night. That is one of the many reasons people that are travelling in the desert travel at night; so they can avoid the heat of the day.
There are no clouds to stop the heat escaping.
You know the deserts are very hot places, but did you know that they can become very cold at night? The sky above a desert is usually very clear. So during the day, the ground absorbs most of the sunlight that strikes it, heating the surrounding air.
At night the reverse happens. Since there are no clouds over a desert to trap the heat, the land gives off heat rapidly, and it becomes very chilly. In fact, though daytime temperatures in the desert average 38 c, in some deserts it can get down to -4 c at night.
Because during the day there are no clouds to block the sun- this means it will be extremely hot. However there are no clouds at night meaning that the heat is not locked in underneath the clouds. This means that the heat can just rise leaving the desert very cold at night.
What is the second largest desert next to the Sahara?
The second largest desert in Africa is the Kalahari Desert between Botswana and South Africa.
The Kalahari Desert is second, behind the Sahara. The Kalahari covers much of Botswana, parts of Nambia, and a portion of Soouth Africa.
How does a nomadic tribe survive in the harsh climate of the Sahara Desert?
there's much to say to unswer this question.
The tribes dig water wells in many different places of the desert mainly where rains often falls, that means grass for their cattle. People since childhood learn by heart the locations of all the waterwells.
Some times, when someones get stuck without water in the summer days, he tends to kill his camel and drink its stored water.
People exchange goods without need to have cash. one goat can be exchanged for example for 3 bags of rice (150 kgs)
What type of work do people in the Sahara Desert do?
The Sahara Desert encompasses a large portion of north Africa and is not just one huge expanse of sand; it is comprised of sand fields, mountain ranges and rocky outcrops.
Many cities and towns are actually located within the loose geographic area which is known as the Sahara Desert.
I believe the question is more on how the nomadic inhabitants of the area live and work. By definition they move from area to area depending on the season and supply of water. Most could be defined as traders or nomadic farmers (camel, goats).
What are some carnivores of the Sahara Desert?
In North America some of the desert predators are:
Coyotes
Wolves
Foxes
Cougars
Bobcats
Coatis
Raccoons
Skunks
Eagles
Hawks
Owls
Snakes
Lizards
Toads
Salamanders

What is the ecosystem of the Sahara desert?
The Sahara desert is the world's largest hot desert and is about the size of Brazil. The physical processes that occur in the Sahara are much the same as they are in other hot deserts of the world.
Where in africa is the sahara desert?
North Africa
The Sahara is located in northern Africa and covers nearly a third of the continent.
The Sahara occupies most of the northern third of the African continent. It is the largest hot desert in the world and second largest desert overall. Only the Antarctic Desert is larger.

I am Dylan Hili and i love ellie jones, paula wallwork, khlsey, sinead and i am a thicko who is in CAU!
How does a cactus grow in the Sahara?
A cactus isn't native to the Sahara Desert. One challenge is the sandy terrain, which may drain way too fast and hold not enough moisture for cactus plants. Another is represented by the high heat and light levels. Temperatures may be too wide ranging for a cactus plant's vulnerability to scorching and freezing at the extremes.
Otherwise, it's possible that desert and jungle cactus plants may handle the most hospitable environments of desert oases. A jungle cactus may be able to find a tree on which to anchor, as it does in the subtropics and tropics. In this way, its airy roots are in the humid, shaded environment that they're used to in a jungle.
Clarification:
Cacti are natives of the Americas, they are not native to Africa.
Do thunderstorms occur in the Sahara Desert?
yes it did snowed in kalahari desert in africa for the first time in 1981. The temprature dropped to a chilly minus 5 degrees C
