The Dead Sea is a famous saltwater lake in southwest Asia. Its surface is 392 meters below the Mediterranean sea level, which is the lowest place in the world. Because of its high temperature, strong evaporation and high salinity, it reaches 25%-30%. It is said that except for a few microorganisms, aquatic plants and fish can't survive, hence the name Dead Sea. Although there are no aquatic animals and plants in the Dead Sea, it takes good care of human beings because it allows people who can't swim to swim in the sea. Anyone who falls into the dead sea will be lifted up by the buoyancy of the sea. This is because the proportion of water in the Dead Sea is1.17 ~1.227, while the proportion of human body is only 1.02~ 1.097. The proportion of water exceeds that of human body, so people will not sink. The tour guide of the travel agency took incredible photos: tourists lay leisurely on their backs on the sea, holding colorful umbrellas in one hand to shade themselves, and looking at pictorial in the other, drifting with the tide. The seawater of the Dead Sea is not only high in salt, but also rich in minerals. Often soaked in seawater can treat chronic diseases such as arthritis. Therefore, it attracts hundreds of thousands of tourists to come here for vacation and recuperation every year. Tourists smear mud on the Dead Sea [3] The black mud at the bottom of the Dead Sea is rich in minerals and has become a sought-after skin care and beauty product in the market. Israel has opened dozens of beauty sanatoriums on the Dead Sea. The convalescents are covered in black mud, leaving only two eyes and lips exposed. The dead sea black mud, which is rich in minerals, has become a valuable export product of Israel and Jordan because of its special effects of fitness and beauty. The Dead Sea is the earliest sanatorium in the world (since Herod's time), and a large number of minerals in the lake have certain soothing and analgesic effects. Thousands of people came to the Dead Sea from all over the world to restore their energy and health. The magical effect of the Dead Sea comes from the following aspects: ▲ The sun shines on the Dead Sea almost every day of the year. Because the area is below the sea level, sunlight has to pass through the special atmosphere, the natural filter formed by chemical elements brought by seawater evaporation and the thick ozone layer. In this way, some ultraviolet rays are blocked, and people can safely bask in the sun for a long time here. ▲ Atmospheric seawater rich in minerals evaporates, leaving a unique group of oxidized salts-magnesium, sodium, potassium, calcium and bromine. Bromine is famous for its sedative effect, and its density in the air around the Dead Sea is 20 times higher than anywhere else on earth. ▲ Mineral hot springs are rich in high concentrations of salt and hydrogen sulfide. Dead Sea mud contains a lot of sulfides and minerals. It can keep warm, clean skin and relieve joint pain. ▲ Warm air with dry temperature, continuous high temperature and scarce rainfall. ▲ The high-pressure Dead Sea is the place with the highest pressure on the earth. The air contains a lot of oxygen, which makes people feel comfortable to breathe. ▲ Less pollen, dry climate, fewer plants and no allergens.
To the north of the Mediterranean is the European continent, to the south is the African continent and to the east is the Asian continent. It is about 4,000 kilometers long from east to west, 1800 kilometers wide from north to south, and covers an area of about 2512,000 square kilometers (970,000 square miles). It is the largest land ocean in the world. Apennine Peninsula divides it into east and west parts, and Apennine Peninsula is the Tunisian Strait between Sicily and Tunisia. Average depth 1450m, deepest point 5092m. High salinity, up to 39.5‰. The deepest recorded point in the Mediterranean Sea is the Ionian Basin in southern Greece, which is 5 1, 2 1 m (16,800 ft) below sea level. The Mediterranean Sea is the oldest ocean in the world, and its history is even older than the Atlantic Ocean. The western part of the Sea of China is connected with the Atlantic Ocean through the Strait of Gibraltar, and the eastern part is connected with the Black Sea through the Turkish Strait (Da Daniil Strait and Bosporus Strait, Marmarahi). The western end communicates with the Atlantic Ocean through the Strait of Gibraltar, and the narrowest point is only 13km(8 miles). The waterway is shallow. The northeast is connected with the Black Sea through the Da Daniil Strait-Marmarahy-Bosporus Strait. The southeast is connected with the Red Sea through the Suez Canal, which was opened in19th century. The Mediterranean Sea is one of the oldest oceans in the world, while the Atlantic Ocean connected with it is a young ocean. Located at the junction of Eurasian plate and African plate, the Mediterranean Sea is one of the strongest seismic zones in the world. There are Mount Vesuvius and Mount Etna in the Mediterranean region. The Mediterranean coast is hot and dry in summer and warm and humid in winter, which is called the Mediterranean climate. Vegetation, with hard leaves, waxy leaves and deep roots, has the characteristics of drought tolerance to adapt to the dry and hot climate in summer and belongs to subtropical evergreen broad-leaved forest. It is the main subtropical fruit producing area in Europe, rich in citrus, figs and grapes, as well as woody oil crops olive. The earliest Jews and ancient Greeks called it "sea" or "sea" for short. Because ancient people only knew that this sea was located between three continents, it was called "Mediterranean". English, French, Spanish, Portuguese, Italian and other languages are all spelled from the Latin MareMediterraneum, in which "medi" means "between" and "terra" means "land", and the full name is "the ocean in the middle of land". This name first appeared in ancient books in the 3rd century. In the 7th century AD, the Spanish writer Isir took the Mediterranean as a geographical name for the first time. The Mediterranean was once thought to be the remnant of the Tethys Sea that surrounded the old hemisphere. It is now known that it is a relatively young basin in structure. Its continental shelf is relatively shallow. The widest continental shelf is located in Gabes Bay on the east coast of Tunisia, with a length of 275km (170 miles). Most of the bottom of the Adriatic Sea is also a continental shelf. The Mediterranean sea floor is a sediment composed of lime, mud and sand, with blue mud below. The coast is generally steep and rocky, with deep serrations. The Dragon River, the Po River and the Nile River are just a few big deltas in the Mediterranean. The continuous injection of Atlantic surface water is the main supplementary source of Mediterranean sea water. The most stable part of its seawater circulation is the water injected into the coast of North Africa through the Strait of Gibraltar. The whole Mediterranean basin is active in structure and earthquakes often occur. It is one of the strongest earthquake zones in the world. Here, the underwater crust is broken, earthquakes and volcanoes are frequent, and the world-famous Vesuvius and Mount Etna are distributed in this area. There is a ridge between Sicily and the African continent, which divides the Mediterranean into two parts. There are three main basins separated by seamounts in the western Mediterranean. From west to east: Alboran basin, Algeria basin and wide basin. The eastern Mediterranean is the Ionian Basin (Adriatic Sea in the northwest) and the Levant Basin (Aegean Sea in the northwest). The big islands in the Mediterranean are Mallorca, Corsica, Sardinia, Sicily, Crete, Cyprus and Rhode Island. The three peninsulas in southern Europe and Sicily, Sardinia and Corsica divide the Mediterranean Sea into several small sea areas: Goulias Sea, tyrrhenian sea, Adriatic Sea, Ionian Sea and Aegean Sea. The Mediterranean sea floor is undulating, with ridges and basins interlaced. It is divided into east and west parts, bounded by Apennine Peninsula, Sicily and Tunisia in Africa. The eastern Mediterranean is much larger than the western Mediterranean, with rugged seabed and different depths. The shallowest place is only tens of meters (such as the northern Adriatic Sea), and the deepest place can reach more than 4000 meters (such as the Ionian Sea). In some places, the water depth difference between the bow and stern of a sailboat is as high as four or five hundred meters. The Mediterranean climate is mild and rainy in winter and dry and hot in summer. Except for the eastern part of Tunisia on the south bank, air flows into the Mediterranean Sea through gaps between mountains. The annual rainfall in most parts of the coast of North Africa rarely exceeds 250 mm (65,438+00 inches), while the annual rainfall in some parts of rugged Dalmatia in Croatia is 2,500 mm (65,438+000 inches). Although there are many rivers flowing into the Mediterranean, such as Nile, Rhone and Ebro. Because it is located in the subtropical zone, the evaporation is too large, far exceeding the supply of river water and rainwater, making the water income in the Mediterranean less than the expenditure. Due to the temperature difference of seawater and the salinity of the Atlantic Ocean, the seawater of the Mediterranean and the Atlantic Ocean can be exchanged regularly. Low salinity Atlantic seawater flows into the Mediterranean Sea from the surface of Gibraltar Strait to supplement the evaporated water source. The Mediterranean sea with high salinity sinks and flows into the Atlantic Ocean from the lower layer of the Strait of Gibraltar, forming a seawater circulation, up to 7000 cubic meters per second. Without the continuous water supply from the Atlantic Ocean, the Mediterranean will dry up and become a huge salt pit in about 300 years.
