This area is bigger than 70% countries in the world. Why is this lake mistaken for the sea?

There is such a lake, which is obviously a lake, but it is mistaken for the sea. This misunderstanding lasted for thousands of years. Even the names are named after the sea. This unique lake, called Caspian Sea, is the largest inland water body in the world. The Caspian Sea is bigger than 70% countries in the world. It can be said that the Caspian Sea is a giant in the lake. According to statistics, the Caspian Sea covers an area of 370,000 square kilometers, with the deepest point of 1.025 meters, which is thousands of kilometers long. The Caspian Sea is the largest and longest lake in the world, and its depth and length exceed some sea areas on the earth. Perhaps because of its vastness and grandeur, it has been mistaken for the sea for thousands of years. In fact, the Caspian Sea is just a saltwater lake, and the salinity of water is only 1/3 of that of seawater, but ancient people could not tell the difference between a saltwater lake and the sea. Studying the data left in ancient times, we can find that both Greeks and Persians called the Caspian Sea the sea in ancient times. Many later races also called the Caspian Sea the sea. Ancient observation methods should be backward, so it is impossible to recognize that the Caspian Sea is actually a lake. However, with the rapid development of modern science and technology, people have confirmed through scientific exploration that the Caspian Sea is actually a lake. Unexpectedly, we can find from many materials that the Caspian Sea was indeed a sea about millions of years ago, but after great changes, it gradually became a lake. Today, the Caspian Sea is rich in tourism resources. Some resorts have been developed around the Caspian Sea, and many tourists come to visit them every year. Moreover, the Caspian Sea also contains a large number of mineral resources, which are of great development value. The Caspian Sea is also rich in oil resources, which have been exploited by many neighboring countries. These countries have earned a lot of foreign exchange from this oil, and now they are among the rich countries. However, many countries are vying for the ownership of the Caspian Sea, and there is no conclusion yet. This also has a certain impact on tourism and mineral resources development in the Caspian Sea.

The famous Caspian Sea is actually a lake, isn't it amazing?
