There are countless rivers and lakes in the world, which are embedded in this wonderful and magical planet, like shining necklaces and precious jewels. Gurgling streams, surging rivers, suspended waterfalls and calm lakes have formed an indissoluble bond with human beings since ancient times. They adorn human life and bring people reverie, joy and strong interest. And some grotesque rivers and lakes, with their beautiful posture and rich reserves, have aroused great interest and enthusiasm for exploration. The world of vast expanse is full of wonders, and countless new "mysteries" of nature are waiting for us to seek and explore. Xiang River In Angola, Africa, there is a river with a total length of only six kilometers called Lenida River. Although the river is short, it is famous for its fragrant smell. When people come more than 0/00 meters away from the river/kloc-,they can smell the strange fragrance floating in their noses. The closer they are to the river, the stronger the fragrance. Some people say that there are countless underwater plants at the bottom of the Lenida River. They can produce fragrant flowers in water, which dissolve in water and evaporate into the air. It is also said that the soil at the bottom of this river is very special, and the sediment itself contains strong aromatic substances, which constantly exudes fragrance to the surrounding area. "Sweet" River In Italy, an unknown river turned out to be sweet, as if someone had put countless sugars in it. However, although the river is pure and sweet, absolutely no one on both sides dares to drink it. Only this sweet water is used to irrigate the land, and the crop harvest is usually good. Biologists point out that sweet water is obviously less irritating to plants and animals than salt water. Therefore, saltwater fish can live comfortably in this fresh water. So why is the water in this river sweet? Geologists say that the formation of river sweetness is related to the soil in the river bed, and the soil at the bottom of this sweet river may contain high-purity raw sugar crystals. The "acid" river is a rare and famous acid river that passes through the Rio Virally River in the Colombian volcanic area of South America. In fact, its sour taste is not strong, but if someone accidentally swallows a few mouthfuls of sour river water, it will cause tongue ulceration, gastrointestinal damage, unbearable pain and difficult to heal. In this river, fish, shrimp, crabs, mussels and other aquatic animals and plants can't survive, which is a veritable "river of death". It turns out that this 580-kilometer-long Leo Virally River contains 8% sulfuric acid and 5% hydrochloric acid. Geologists' exploration shows that plessy volcano erupts constantly, and a large amount of hydrochloric acid and sulfuric acid produced by it is injected into rivers through numerous deep caves, making rivers acidic. "Acid Lake" There are acid rivers and acid lakes in the world, and there is an acid lake in Sicily, Italy, which is comparable to the acid river. There are two mysterious fountains at the bottom of the lake, which continuously spray highly corrosive acidic spring water into the lake. In this lake, not only ordinary microorganisms are difficult to survive, but even animals that sneak into the lake will soon be corroded to death by this acidic lake, and no one will be spared. Located on the border between Jordan and Israel, the Dead Sea is the saltiest lake in the world. Its area is about 1000 square kilometers, the lake surface is 392 meters lower than the Mediterranean, and the salt content is as high as 27.2%, which is eight or nine times more salty than normal seawater. Visitors who have just arrived at the Dead Sea want to taste the lake, but as long as they lick it a little, they will immediately feel a sharp pain, bitter, astringent and salty. But the greatest advantage of the Dead Sea is that people and animals will not drown if they fall into it. It is said that in 70 AD, the Roman commander Imperial Capital surrounded Jerusalem and threw prisoners in handcuffs and shackles into the Dead Sea for execution. Strangely, it didn't sink several times in a row. The Imperial Capital was very surprised. He thought that God protected him, so he ordered all the prisoners to be pardoned. "Fire" Lake has a sparkling lake on the Grand Bahama Island in the West Indies of Latin America. Whenever people go boating on the lake in a quiet night, they will see thousands of lights splashing from the rising and falling paddles, and beautiful sparks shining around the boat. If you paddle the lake, it will arouse more sparks. Occasionally, a fish with fiery red flowers will jump out of the lake, then splash, and golden flowers will fly, forming a mysterious and attractive spectacle. It turns out that there are countless dinoflagellates growing in the lake, which contain fluorescein and luciferase. When the lake is stirred, fluorescein and luciferase will combine with air to produce oxidation and emit colorful sparks. "Five-story" Lake There is a lake named mcquarrie on Chirisi Island in Barents Sea. It has five layers of water from shallow to deep, and the water quality is different. The bottom of water is full of hydrogen sulfide, and there is no life except some bacteria that can survive under severe hypoxia. The penultimate layer of water is crimson, which is caused by bacteria floating up from the bottom of the lake. The third layer is transparent salt water, in which a large number of algae, anemones, starfish, sea bass and cod live, but they can't swim to the lower layer because there is enough hydrogen sulfide to kill them. The fourth layer of water is slightly salty and light, which is also not suitable for the survival of the above marine life. Jellyfish, some freshwater fish and some marine life that can live in fresh water live in this layer of water. The top layer is standard fresh water, where all kinds of freshwater fish and other freshwater creatures live and multiply. "Oil" Lake Venezuela is known as the "oil kingdom" and has a famous oil lake-Lake Maracaibo. The lake area 14000 square kilometers and depth 1500 meters contain more than 5 billion barrels of crude oil, accounting for 25% of the national oil reserves. Every day, crude oil gushes from the cracks in the asphalt at the bottom of the lake, with a daily output of 2 million barrels, accounting for 80% of the national oil output. It is really a veritable "underground oil depot". Looking from the misty lake, you can see many derricks and oil towers, and the gas injection station in the lake stands in the blue waves. Three-story reinforced concrete buildings continuously extract natural gas from the ground and then re-inject it into the ground to improve the oil layer and ensure stable and high yield. Lake Maracaibo is really a veritable oil lake. "Asphalt" Lake is located in the southwest of Trinidad in Latin America, with a natural asphalt lake. The lake is about 0.44 square kilometers, dark gray in color and full of high-quality asphalt. Someone once drilled down more than 90 meters in the middle of the lake and took out the asphalt. 100 for more than a year, people have been mining 30 to 40 tons of asphalt from the lake every day, but new asphalt is still emerging from the bottom of the lake, so the lake has not declined at all. The asphalt here is excellent in texture, and the road paved with it is called "ash flash road", which is especially suitable for vehicles to drive at night. The first expressway from London, the capital of England, to Birmingham was paved with the natural asphalt of this lake. Interestingly, this wonderful asphalt lake is also a natural history museum. During the excavation, people excavated many bones and teeth of prehistoric animals, weapons and utensils used by ancient Indians, and various bird fossils. Once, a trunk with a history of more than 5,000 years and a height of more than four meters appeared in the lake. The "natural gas" lake is at the junction of Zaire and Rwanda, and there is a natural gas lake in Kivu. The lake covers an area of about 2500 square kilometers, and extremely rich natural gas is dissolved in this huge lake. According to experts' estimation, the natural gas reserves of Lake Kivu will not be less than 50 billion cubic meters. This is indeed a considerable wealth in today's increasingly tense world energy. "Borax" Lake Teias Codon is a famous borax lake in Chile, South America. The lake is about 40 kilometers wide and white from a distance. There is a thick crust on the lake, which looks like a huge ice floe. It turned out to be high-purity borax. Borax Lake provides Chile with another rich mineral resource besides copper and saltpeter. The "medicinal mud" lake is located in the beautiful Black Sea. There is a Keol Lake in Tequil, with an area of 1000 hectares, which produces a peculiar medicinal black mud. The salt content of lake water is 6 times higher than that of ordinary seawater, and there are 150 kinds of animals and plants living in the water. These animals and plants grow, reproduce, die and rot in the lake, and finally deposit at the bottom of the lake, forming a thick black mud layer. Black mud is rich in minerals such as iodine, sodium, potassium, iron and calcium. Many patients from Western Europe and North America came to Wan Li for medical mud therapy. They usually cover their whole bodies with black lake mud, then lie on the beach and let the sun bathe, or mix lake mud with water to make mud and soak it in it. It is said that this patch can treat many diseases, especially intractable skin diseases.
