How dangerous is the Sahara Desert, and why is it so difficult for people in the vicinity to enter i

In the desert, the temperature difference between day and night is too large, the day is too hot and the night is too cold, in addition, the desert is also very scarce in water, and because of the similar environment, it is easy to get lost.

The Sahara Desert is very dangerous because it spans a very large area, so many people are afraid to enter it easily.

Someone lives. There are many cities near the Sahara, such as Cairo, Tripoli and the like. In the heart of the Sahara Desert, there are many ethnic groups, such as the Bedouins.

The Bedouins are the Arabs who live a nomadic life in the desert wilderness based on their clan tribe. It is mainly distributed in the vast deserts and wilderness areas of West Asia and North Africa, and belongs to the Mediterranean type of Europa race.

Bedouins (also known as bedouins, also known as Bedouins) is an Arabic transliteration, meaning "nomads in the wilderness", "people who live in pursuit of water and grass", and are part of the Arab nation. Bedouins everywhere speak the local Arabic dialect and Arabic script.

It is inhabited at the edge of the desert and in the larger oases in the desert.

There are five main reasons for the formation of the Sahara Desert: because it is located on both sides of the Tropic of Capricorn, Lana is controlled by the subtropical high pressure zone all year round, and the dry and hot downdraft prevails, and the northern part of the African continent is wide, and the range of the subtropical high pressure zone is large, and the area of solid dry heat is wide; North Africa is close to the Asian continent, and the northeast trade winds blow from the eastern land, which is not easy to form precipitation, making the north more dry. The coastline of North Africa is too straight, with the Ethiopian plateau on the east side, which prevents the moist air flow from entering the interior; The Canary cold current passes through the west coast of North Africa, which has a cooling and dehumidifying effect on the western coastal areas, bringing the desert closer to the west coast. The terrain of North Africa is relatively homogeneous, with flat terrain and small undulations, plus a single climate, forming a large desert area.

Summary. Disadvantages: The desert environment is bad, survival needs water, food, warmth, and shelter to rest, but people are very passive in the desert, if they do not find a cool shelter during the day, they may suffer from heat stroke, and what is more disgusting is the temperature difference between day and night of nearly 30 °, and it will also lead to hypothermia if they don't have time to make a fire at night.

During the day, you need to consume a lot of body fluids to find shelter, and then you have to live at night to keep warm, and the desert is a barren land with very little water, even if you use the water vapor of the temperature difference between day and night to get precious water, but you can't get people out of the desert at all.

The good and bad of tourists going to the Sahara Desert.

During the day, you need to consume a lot of body fluids to patrol the shelter and lack of benches, and then you have to live at night to keep warm, and the desert is a barren land with very little water, even if you use the water vapor of the temperature difference between day and night to obtain precious water, but the thick cover cannot let people out of the desert.

Benefits: Stretches of sand, dromedary camels, vast expanses of golden yellow, and enduring love stories. Some parts of the Sahara Desert are off-limits to tourists, but there are still some very characteristic and chaotic sites that can be visited, especially in Morocco, Tunisia and the parts of Ainehu.

Because the Sahara Desert is controlled by the subtropical high all year round, it is a downdraft, and the wind is small, making it difficult to blow the sand.

Under the action of directional winds, the movement trend of the desert tends to the direction of the wind direction, and it is constantly moving, such a desert is called a "mobile desert".

Two mobile deserts:

The Rub al-Khali Desert (Arabic: meaning "empty quarter", named for its area of about a quarter of the Arabian Peninsula, is one of the largest deserts in the world, covering the entire southern region of Saudi Arabia and most of the territories of Oman, the UAE and Yemen. Also known as the Arabian Desert.

It is roughly northeast-southwest trending, with a length of 1,200 kilometers, a width of about 640 kilometers, and an area of 650,000 square kilometers. It is mostly red because it is rich in iron oxide. 100,500 meters above sea level.

The Rub al-Khali Desert is the largest mobile desert in the world.

The Taklamakan Desert, located in the Tarim Basin of southern Xinjiang, means "place where you can't get in and out" in Uyghur language, and locals often call it the "Sea of Death". The whole desert is about 1,000 kilometers long from east to west, about 400 kilometers wide from north to south, with a total area of 337,600 square kilometers, which is the largest desert in China and the second largest mobile desert in the world.

The Sahara is a mobile desert with a loss of dust, and the Sahara Desert is the largest desert in the world. Several countries such as Brother, Tung and Egypt, Sudan and Libya cover an area of more than 8 million square kilometers. The climate here is various, the temperature is abnormal, and sometimes there is not a drop of rain in some areas for consecutive years, and the highest temperature in a year sometimes reaches 58, and the lowest can be minus 15.

It stretches for thousands of miles without a single house, and it is difficult to see a small grass.

What's even more amazing is that the desert is now moving southward at an average rate of kilometers per month, and in some areas it is moving southward at a rate of kilometers per month.
