The sea is also called the "big sea", which refers to the large salt water area connected to the "ocean", that is, the attached part of the edge of the ocean. Generally, large inland salt lakes and large saltwater lakes that are not connected to the ocean, such as the Caspian Sea and the Sea of ??Galilee, are not "sea". The role of sea areas for human beings is not only to provide a rich variety of available resources, but also to benefit humans.
The sea is at the edge of the ocean and is a subsidiary part of the ocean. The area of ??the sea accounts for about 11% of the ocean. The water depth of the sea is relatively shallow, with the average depth ranging from a few meters to 3,000 meters.
Because the sea is close to the continent, the temperature, salinity, color and transparency of the water change significantly due to the influence of the continent, rivers, climate and seasons. In some sea areas, the water sometimes freezes in winter. The salinity of sea water near the mouth of a river will become lighter and the transparency will be poor. Compared with the ocean, the sea does not have its own independent tides and currents.
Knowledge expansion:
In terms of water bodies, the sea is a subsidiary part of the ocean, but in essence the sea is a submerged continent. The main body is located on the continental shelf, and the crust below it is the continental crust. . Underneath the ocean is the oceanic crust. From this arises a series of differences. Of course, with geological movements, seas and oceans can transform into each other.
Seawater destroys the coast and seabed through its own power, which is divided into wave impact, wave abrasion (the erosion of the coast by sediment carried by waves) and seawater dissolution.
Lateral movement, sediment movement perpendicular to the coastline, inflow bridges and outflows cause sediment to move seaward or shoreward. In the neutral belt, the sediment only moves back and forth, while No substantial migration.
Longitudinal movement, sediment movement parallel to the shoreline. In fact, it is a superposition of the above two movements. In addition, the sea also has strong erosion, transport, and sedimentation capabilities, thus depositing some sediments in submarine canyons, deep-sea fans, continental rises, and abyssal plains.
On the coast of the Bohai Sea are Liaodong Bay, Bohai Bay and Laizhou Bay. Rivers such as the Liaohe River, Haihe River, and Yellow River bring a large amount of organic matter from the land, making it a natural fishing ground rich in shrimps, crabs, and yellow croakers.
