Comparison of the Persian Gulf and the Baltic Sea, what kind of sea is the Baltic Sea?

Similarities: both waters are located on important transportation arteries, and many large ports have been built on the shore, carrying a large amount of shipping;

Differences: The waters of the Persian Gulf have high salinity, while the waters of the Baltic Sea have the lowest salinity; The two bodies of water are located in different temperature zones.

The Persian Gulf is a bay located near the Strait of Hormuz and surrounded by an abundance of oil; The Baltic Sea is a sea area located in the Indian Ocean!

The Persian Gulf, as an important passage of the world's energy hub, has an important position in the world.

The Persian Gulf is located in the heart of the Middle East, between Iran and the United Arab Emirates, and is rich in oil resources.

The Baltic Sea is one of the most important inland seas in Europe, and because it is not well connected to the open sea, it is also the least salinous sea in the world.

The fourth floor is about the Mediterranean...

Both are rich in oil, both are arteries of transportation, the Baltic Sea controls the life of all of Northern Europe, the north freezes for three or four months a year, and there are many coastal seaports, which are fed by more than 250 rivers.

The Persian Gulf is tropical.

The Persian Gulf has more oil than the Baltic Sea.

The Persian Gulf is located in the Middle East, connected to the Arabian Sea by the Strait of Hormuz, surrounded by Islamic countries, and is currently the world's main oil producing area, but due to the tense situation in the Middle East, the entrance to the Strait of Hormuz often has a blockade.

Located at the confluence of Europe and Africa, the Baltic Sea is connected to the Atlantic Ocean by the Strait of Gibraltar to the west and the Red Sea to the east by the Suez Canal. The Baltic Sea region is also a place where ancient European civilizations flourished, and ancient European countries such as Greece and Italy have territories located on the Baltic Sea.

What are you going to compare? Is it the area of marine fish? Or is it the abundance of fish? Or is the water quality good or bad? And then the salt content?

The Baltic Sea is the least salinized sea in the world, and it was formed after the end of the last glacial period and the massive melting of glaciers. The Baltic Sea is the least salinized sea due to its shallow water, little exchange with the open sea, and 250 large and small rivers feed it, combined with the cold climate and particularly slow evaporation. The salinity of its seawater is only 7.8%, which is significantly lower than the average salinity of the world's seawater (35%), and the salinity of the Baltic Sea bays is even lower, only about 2%.

The Baltic Sea is an inland sea in northern Europe, which is almost surrounded by land on all sides, and is only connected to the North Sea in the west by the Øresund Strait, the Kattegat Strait and the Scalolac Strait.

The Baltic Sea is an important waterway in Northern Europe, which is connected to the White Sea through the North Sea-Baltic Sea Canal, and connected to the Volga River through the Lenin-Volga-Baltic Sea Road, and the larger ports along the coast include St. Petersburg, Stockholm, Rostock, etc. However, the northern and eastern seas usually have a period of ice cover each year that is not conducive to shipping.
