The area of Sahara Desert Sahara Desert is 9.32 million square kilometers.

the Sahara desert was formed about 2.5 million years ago in the Sahara desert, which is the largest sandy desert in the world, with an area of about 9.32 million square kilometers, located in the northern part of Africa. The climate in this area is very bad, which is one of the most unsuitable places for living things on earth. "Sahara" is a transliteration of Arabic. In Arabic, "Sahara" is a big desert, which comes from the language of Tuareg, a local nomadic people, and its original meaning is "big desert".

The Sahara Desert is the largest desert in the world except Antarctica, which is located in the northern part of Africa, from the Mediterranean Sea to the Sudan grassland. It is located in the south of Atlas Mountains and Mediterranean Sea (about 35 N) and north of 14 N (25 mm isohyet). Across the northern part of the African continent, it is 5,6 kilometers long from east to west and 1,6 kilometers wide from north to south, accounting for about 32% of the total area of Africa.

Reasons for the formation of the Sahara Desert

(1) North Africa is located on both sides of the Tropic of Cancer, which is controlled by subtropical high pressure belt all the year round, and hot and dry downward flow prevails, and the African continent is narrow in the south and wide in the north, which is controlled by subtropical high pressure belt and has a wide hot and dry area.

(2) North Africa is close to the Asian continent, and the northeast trade wind blows from the eastern land, which makes it difficult to form precipitation, making North Africa drier.

(3) The coastline of North Africa is straight, and there is an Ethiopian plateau in the east, which blocks the humid air flow and makes the vast inland areas unaffected by the ocean.

(4) There is a Canary cold current passing through the west coast of North Africa, which plays a role in cooling and dehumidifying the western coastal areas and makes the desert approach the west coast.

(5) North Africa has a single topography, flat terrain, little fluctuation and a single climate, forming a large desert area. Where is the Sahara desert?

the Sahara desert is in the north of Africa.

The Sahara Desert is located in the north of Africa, north to the Mediterranean Sea, south to the Sudan Grassland, Atlas Mountains and the south of the Mediterranean Sea, about 35 N, about 14 N, and north to the 25 mm isohyet.

The Sahara Desert is the largest desert in the world, covering almost all of northern Africa and accounting for a quarter of the total area of the whole continent. The desert is about 4,8 kilometers long from east to west and 1,3 to 1,9 kilometers from north to south, with a total area of about 9,65, square kilometers. Across the northern part of the African continent, it is 5,6 kilometers long from east to west and 1,6 kilometers wide from north to south, accounting for about 32% of the total area of Africa.

Introduction

The Sahara Desert makes people yearn for its spectacular desert scenery, vast sand sea, exquisite sand dunes and charming desert customs. The Sahara desert was formed about 2.5 million years ago. The climate of the Sahara desert is controlled by the north-south transition of the trade winds, and there are often many extremes.

It has the highest evaporation rate in the world, and it has the largest area record of no rain for several years. The temperature can reach frost and freezing at high altitude, while the hottest weather in the world can be found at low altitude. Introduction to the Sahara Desert What is the introduction of the Sahara Desert

1. The Sahara Desert was formed about 2.5 million years ago, and it is the largest sandy desert in the world, with an area of about 9.32 million square kilometers, located in northern Africa. The climate in this area is very bad, which is one of the most unsuitable places for living things on earth.

2. "Sahara" is a transliteration in Arabic. In Arabic, "Sahara" is a big desert, which comes from the language of Tuareg, a local nomadic people, and its original meaning is "big desert".

3. The Sahara region is vast and sparsely populated, with an average of less than one person per square kilometer. Mainly Arabs, followed by Berbers, etc. Residents and agricultural production are mainly distributed in the Nile valley and oasis, and some are mainly nomadic. Which country does the Sahara desert belong to?

The Sahara Desert belongs to Egypt. It was formed about 2.5 million years ago, and it is the second largest desert in the world after Antarctica, with an area of about 9.6 million square kilometers, and the largest sandy desert in the world. Located in the north of Africa, the climate in this area is very bad, which is one of the most unsuitable places for living things on earth.

The Sahara desert is divided into several parts: Western Sahara; Central plateau mountains (including Ahagar Plateau in Algeria, Aier Plateau in Niger and Tibesti Plateau in Chad); The eastern part is the most desolate area, which is Tenere Desert and Libyan Desert. The highest point of the Sahara Desert is Kuxi Mountain in Tibesti Plateau, with an altitude of 3415m.

Extended data

Climatic conditions of the Sahara Desert:

The Sahara Desert is dominated by two climatic situations _ the northern part is an arid subtropical climate and the southern part is an arid tropical climate. The arid subtropical climate is characterized by large annual and daily temperature changes, from cold to cool winter and hot summer to the highest precipitation.

the annual average daily temperature is about 2℃(68_). The average winter temperature is 13℃(55_). It is extremely hot in summer. The highest temperature in Al-Aziziyah, Libya, reached a record 58℃(136_). The annual precipitation is 76 km _(3_), although the rainfall varies greatly, most of it occurs from December to March. Another precipitation climax is August, which is characterized by thunderstorms.

Baidu Encyclopedia-Where is the Sahara Desert

The Sahara Desert is in the north of Africa.

The Sahara Desert, which was formed about 2.5 million years ago, is the largest sandy land in the world, with an area of 9.23 million square kilometers. It is located in North Africa. The climate in this area is very bad. The Sahara Desert starts from the Atlantic coast in the west, borders the Atlas Mountains and the Mediterranean Sea in the north, borders the Red Sea in the east, and reaches the Sahel at the junction of Sudan and Niger River Valley in the south. It is a semi-desert and semi-grassland transition zone.

Terrain of the Sahara Desert

The Sahara Desert is divided into several parts: Western Sahara; Central plateau mountains (including Ahagar Plateau in Algeria, Aier Plateau in Niger and Tibesti Plateau in Chad); The eastern part is the most desolate area, which is Tenere Desert and Libyan Desert. The highest point of the Sahara Desert is Kuxi Mountain in Tibesti Plateau, with an altitude of 3415m.

The main topographical features of the Sahara Desert include shallow and seasonal flooding basins and large oasis depressions, rocky highlands, steep mountains, and beaches, sand dunes and sand seas. The biggest desert in the world-Sahara Desert

The biggest desert in the world is Sahara Desert. Let me show you around!

When it comes to Sahara, I have to mention a woman and a book, that is Sanmao and her Story of Sahara. In her works, a distant, mysterious, dreamlike, romantic and affectionate Sahara has been achieved. But when you really set foot in the Sahara, you will find that the Sahara is actually a place that has nothing to do with romance.

the hala desert is the largest desert in the world, but this is not her original face. In the Sahara, where sand and stones are everywhere, there are not only wonderful natural landscapes, but also tenacious life. It is hard for people to imagine that there was a prosperous ancient civilization in such a harsh environment if they didn't see the vivid and varied murals with their own eyes.

The Sahara Desert, located in the northern part of the African continent, is the largest desert in the world except Antarctica, which was formed about 2.5 million years ago. The name "Sahara" comes from Arabic and is introduced from the language of Tuareg, a local nomadic people, meaning "Great Desert".

Location

The Sahara desert is bordered by the Atlantic coast in the west, the Red Sea in the east, the Atlas Mountains in the north and Sudan in the south. It is about 5,6 kilometers from east to west, running from north to south for 1,5-2, kilometers, and it crosses the borders of Morocco, Algeria, Tunisia, Libya, Egypt, Mauritania, Mali, Nigeria, Chad, Sudan and other countries. Sahara desert is the largest desert in the world, covering an area of about 9.6 million square kilometers, accounting for almost one third of the entire African continent. The Sahara region is vast and sparsely populated, with an average of less than one person per square kilometer. Arabians are the main people, followed by Bers and others. Residents and agricultural production are mainly distributed in the Nile valley and oasis, and some are mainly nomadic. Since 195s, abundant minerals such as oil, natural gas, uranium, iron, manganese and phosphate have been discovered in the desert, which has changed the economic outlook of some countries in this area.

The Sahara Desert is divided into three parts: Western Sahara, the central plateau and the eastern desert. The mountainous areas in the central plateau include the Ahagar Plateau in Algeria, the Aier Plateau in Niger and the Tibesti Plateau in Chad, and the highest point of the Sahara desert is located in Kuxi Mountain in the Tibesti Plateau, with an altitude of 3,415 meters. The eastern part is Tenere Desert and Libyan Desert. The Sahara desert divides the African continent into two parts-North Africa and Southern Africa. The climate and culture of these two parts are completely different. The southern border is semi-arid savanna, which is called "Sahel" in Arabic, and further south is southern Africa with abundant rain and lush plants, which is called "Sudan" in Arabic, which means black Africa.

The Sahara Desert is located near the Tropic of Cancer and has a tropical desert climate. Often controlled by subtropical high pressure downward flow, the climate is very dry, so it is not easy to form rainfall, even if the rainfall is mostly explosive showers. The average annual rainfall in most areas is less than 1 mm, which is the least in the world. In the central area, even a few drops of rain did not fall for several years, such as Kage in the desert area of Egypt, where there was no rain for 17 years. Not only that, the evaporation power is very strong, almost more than 2 times or even 1 times that of precipitation, and the relative humidity of the air is also very small. All this has led to the year-round heat wave rolling in the desert area, and the summer heat is pressing, thus obtaining the title of "World Hot Pole".

If less precipitation and large temperature difference are the characteristics of desert climate, then "windy sand" is a common weather in desert. Especially in spring, sandstorms are prevalent and frequent. Whenever a sandstorm comes, the wind roars, flying sand and stones, and suddenly the sky is dark, quicksand is rolling, and sand dunes move with the wind, engulfing large areas of fertile soil and pastures, burying many towns and villages and blocking road traffic. When the sandstorm subsides, there is a thick layer of dust everywhere, and sand piles or dunes are often piled up at the front of the forest. However, the weather is particularly sunny, and all the scenery seems clearer than usual, giving people the feeling that "the wind is shining over the sand mountains."

In most people's impression, the Sahara should be an undulating area of sand dunes, but in fact there are bare gravel plains, rocky plateaus, steep mountains and salt flats besides sand dunes. The plateau is covered with dry valleys formed by flowing water in the past humid climate. The periphery of the plateau is a large area of rocky desert and gravel desert, and then the sand sea is outside, and the oasis is just an ornament.

The arid landform of the Sahara desert is mainly composed of rocky desert, gravel desert and desert. The storm in the desert blows away the gravel, sand and dust, leaving the rock exposed on the ground, which becomes a rock desert, also known as a stone desert. Stone desert is mostly distributed in the high-lying areas in the central and eastern Sahara. The sand accumulated on the ground was blown away by the wind, leaving stones and stones, which became the gravel desert, which is often called Gobi. Gravel desert is more common between stony desert and desert, and mainly distributed in the rocky areas of Libyan desert, Mount Atras, Kuxi Mountain and other piedmont alluvial fan areas. A large amount of sand deposited in the local area is blown away by the wind, fine dust is blown away, sand is left behind, and the sand carried in the sandstorm is deposited, so that more and more sand is accumulated on the ground, and a sand sea-an endless desert is formed. Except for a few high mountains and plateaus, the desert has the widest area. The famous ones are Libyan Desert, Laibuyanai Desert, Obari Desert, Algerian Eastern Desert and Western Desert, Shesh Desert, Zhufu Desert, Arvana Desert and Bilma Desert. The sand sea with large area is called "sand sea", which is made up of complex and regular sand dunes, with complex and diverse shapes, including tall fixed dunes, low mobile dunes and large areas of fixed and semi-fixed dunes. The mobile sand dunes are constantly moving along the wind, and there was a record that they moved 9 meters a year.

The Sahara Desert has the largest sand sea in the world. Yellow sand dunes as fine as powder, black sand dunes as black as ink, and white sand dunes as white as silver constitute the most splendid landscape. In the desert, it is said that you can often hear a strange scream, like the roar of a beast and the sound of a whistle. Although there is no rhythm, it sounds very strange, and the wind and sand are walking and screaming. Mirages are also often encountered.

There is a desert called Kosapeka near Morocco, with an area of only 8 square kilometers, but on the eastern highlands, there is a very famous "ghost lake". Because its appearance is unpredictable. For example, in the evening, it seems that there is a big lake with a water depth of 1 feet, but in the morning, it has become a big sand dune of more than 1 feet. Moreover, its appearance is irregular, sometimes during the day, and for ten or eight days in a row, the situation remains the same, and the lake is crystal clear and drinkable. In order to verify the existence of the "ghost lake", a group of explorers once camped near the local area. In the middle of the night, the lake suddenly rose from the sand, and the momentum surged rapidly, instantly forming a lake. Fortunately, the explorers escaped in time to survive. But the next day, when they got there again, what they saw was still flat sand. Geogeographers speculate that there may be an underground cavity higher than the "Ghost Lake" near the "Ghost Lake", which stores groundwater seeping from other places, and an underground tunnel like Siphon Spring connects the "Ghost Lake" with the underground cavity. When the siphon phenomenon appears, a large amount of water in the underground cavity flows out, and a "ghost lake" appears. Because the "ghost lake" is located on the desert, even if the water volume is large, < P > it will not take much time to flow under the sand layer or seep to other places. Even if the water that has not seeped out for a while, it will be covered by quicksand and become a vast sea of sand in a short time because of the strong wind in the desert and the wind and sand.

The wind in the desert is very strong, and its power is often unexpected. It can blow away the weathered broken gravel and sand grains on the rock surface and enlarge the cracks and fissures in the rock. At the same time, the gravel and sand carried by the wind abrade the rock wall in the upper part of the rock and the cracks and grooves between the rock blocks, so that the rock blocks are gradually ground and deformed. In addition, it can constantly change its carving techniques and strength with the change of wind power and direction, like a skillful craftsman, making all kinds of shapes more wonderful and magnificent. Therefore, people call these beautifully shaped scenes "wind sculptures".

There are some grotesque earth mountains in the Sahara desert, most of which are eight feet above the ground.
