What is the dirtiest and hottest sea in the world?!

The hottest sea in the world is the Red Sea, the marginal sea of the Indian Ocean. The surface sea temperature of the Red Sea can reach 32 in August, and the water temperature of the sea water can reach 21 even below 200 meters. The dirtiest sea The Mediterranean Sea is the world's largest inland sea and the world's most spoiled sea.

Red Sea and Mediterranean.

The Red Sea, located between Asia and Africa, is the hottest sea in the world, and it is also the youngest sea, it is an area of 450,000 square kilometers, 2,100 kilometers long, an average width of about 290 kilometers, an average depth of 558 meters, the deepest reaches 2,740 meters.

The most peculiar thing about the Red Sea is its "heat". The average annual water temperature on the surface of the Earth's oceans is 17, while the surface water temperature in the Red Sea can reach 27.32 in August, and even at depths below 200 meters, it can reach about 21. What's even stranger is that in the deep basin of the Red Sea, the water temperature is as high as 60!

The Red Sea is controlled by the Tropic of Cancer High Pressure Belt, and is affected by the tropical desert climate of North Africa and the Arabian Peninsula, which is hot and dry all year round, so the water surface is always hot. The expansion of the seafloor has caused cracks in the earth's crust, and the magma is constantly rising along the cracks, and the seafloor rocks are heated, so the bottom of the sea is particularly hot.

The Mediterranean Sea is the world's largest inland sea and the world's most spoiled sea. Every year, 3.5 billion cubic meters of wastewater and 100 million tons of solid waste are dumped into the Mediterranean. The most serious problem is that 58 oil ports in 18 countries adjacent to the sea have caused serious oil pollution when loading and unloading oil.

The hottest sea in the world is the Red Sea, the marginal sea of the Indian Ocean. The surface sea temperature of the Red Sea can reach 32 in August, and the water temperature of the sea water can reach 21 even below 200 meters.

The hottest sea in the world is the Red Sea, located between Asia and Africa; And the coldest sea in the world is the Weddell Sea in Antarctica. The Red Sea is a deep sea with a length of 2,100 kilometers, an average width of 290 kilometers, an average depth of 558 meters, a maximum depth of 2,740 meters, and an area of 450,000 square kilometers. The Red Sea is long and narrow, with a steep coast and a lack of good harbors, and the water is reddish.

The most peculiar thing is the "hot" temperature of its seawater. The average surface temperature of the world's oceans is 17, while the surface temperature of the Red Sea can reach 27-32°C in August, and even in deep waters below 200 meters, it can reach about 21°C. What is even more surprising is that in the deep basin, the water temperature is as high as 60, and the upper part of the water is also 44.

What is it that makes the Red Sea so hot? Many people first consider the geographical location of the Red Sea, which is located between Asia and Africa (from 13°N to 27°N), and the Tropic of Cancer passes through its north, most of which is in the tropics; The abdomen and back are affected by the dry and hot winds of the tropical desert climate of the Arabian Peninsula and North Africa, and the water is always hot all year round. However, it is difficult for this dry heat to reach the depths of the ocean, so why is the temperature in the deep basin floor so high?

It seems that the climate explanation alone is not convincing. Since the advent of the theory of seafloor spreading and plate tectonics in the 60s of this century, it is believed that between Africa and the Arabian Peninsula, there is convection of mantle material under the earth's crust, and convection caused the crust to open and fracture to form the Red Sea today. This tension rift zone is the same area as the Great Rift Valley, which has been going on for 20 million years and is still expanding at a rate of 1 cm per year.

The seafloor expands to create crustal fissures, along which magma rises and heats the rocks on the seabed, resulting in high sea temperatures. This is another explanation for the high sea temperature in the Red Sea. In addition, if the Red Sea continues to expand, I am afraid that in one or two hundred million years, a new ocean will appear here.

The Weddell Sea, located in the Antarctic region, is the largest sea in Antarctica. The sea water here is constantly hit by cold winds from the southern continent (World Cold Pole), so the sea temperature is cold all year round. Due to the large proportion of cold seawater compared to warm seawater, after the cold water sinks, the upper seawater is cooled again, and so on repeatedly, resulting in a particularly low water temperature in the whole sea area.

That's why people call it the "cold sea" on Earth.
