Part One: First Reading Perception

Knowledge link

Yellow Sea my country's Yellow Sea looks yellow-green. This is because a large amount of sediment carried by the Yellow River in ancient times "dyed" the sea water yellow.

Red Sea The Red Sea between Asia and Africa has a very high water temperature, and a kind of algae grows in the sea. After a large number of people die, it turns reddish brown, dyeing the sea water red.

White Sea: The White Sea in northern Russia. Because of its high latitude, it is cold all year round, covered with ice and snow, and has low organic matter content, so the sea water appears white.

Black Sea Due to the injection of water from the Danube, Don, Dnieper and other rivers, the surface density of the Black Sea is low, while the deep layer is affected by the high salinity seawater of the Mediterranean Sea and is very dense. In this way, the density difference between the upper and lower layers is large, making it difficult for water bodies to exchange. The lower seawater has been in an anoxic environment for a long time. The filth secreted by the organisms in the upper seawater and the dead bodies of various animals and plants sank to the depths to rot and smell. A large amount of sludge and turbid water turned the seawater black.
