地圖上，它是一片細小狹長的水域。傳說中，它幫助過摩西和受奴役的猶太人逃出埃及。紅色的海浪翻滾，引人遐思：這紅色是從何而來？不要傳說，不要神話，讓我們聽聽科學的說法吧！

The Red Sea is located between Asia and Africa, and the water is clear, transparent and warm. It is suitable for swimming and bathing. Therefore, the Red Sea attracts lots of tourists. However, in some of the most beautiful places on the Red Sea, the water is the color red.

The hot, dry climate surrounding the Red Sea, causes the water to evaporate quickly, which means the remaining water has a high salt content, which is also called saline. The temperature is also very high. These conditions are suitable for a type of algae to grow. The algae is red in color, and since there is so much of it, it makes the water in the Red Sea appear red.

Also sandstorms from the Sahara Desert also bring red sand that covers the Red Sea and surrounding areas, making it look even more red. After a sandstorm, everything is coated in red sand, creating a uniquely beautiful scene.
