What is the origin of the name Red Sea?

The English name of the Red Sea is "Red Sea", and there are different opinions about the origin of its name. However, most statements are often associated with red.

First, there are many brightly colored shells in the Red Sea, which makes the seawater dark red.

Secondly, there are a lot of coral sand with reddish yellow in the coastal areas of the Red Sea, which makes the sea water red.

Third, the Red Sea has high temperature and sufficient light, which is suitable for biological reproduction. A large number of red algae breed in surface seawater. This algae is abundant, which makes the blue sea water look red.

Fourth, the color of rocks on both sides of the Red Sea is the reason for its name. In ancient times, due to the limitation of traffic conditions, people could only sail on the offshore sea. They found red rock walls on both sides of the Red Sea, especially on the African coast. Under the irradiation of sunlight, the red light on the shore flashes and reflects into the water, turning the sea water red.

Fifth, the name of the Red Sea is related to the climate. On the surface of the Red Sea, there are often westerly winds from African deserts, which bring hot air currents. The red and yellow dust mist carried by the airflow often hangs over the Red Sea, and the sky is dark. Ancient Phoenicians and Greeks sailed here and saw this strange sight of the Red Sea, so people named it "Red Sea".

Sixth, people think that "red" means "south". So the Red Sea is the South China Sea.
