The Red Sea is considered a true diver's paradise and has long been an important transport route for ships. Geologically, it is relatively young and was formed just under 25 million years ago when the Asian and African continental plates split, creating a rift that filled with seawater. The Red Sea is best developed in the area of the Egyptian coast, while many almost untouched coastal strips exist next to it. As a tributary sea of the Indian Ocean, it lies between the northeast of Africa and the Arabian Peninsula. Annually, the Red Sea attracts many vacationers and offers unique beaches and bays. In the water depth of about 538 meters lives a variety of dazzling corals and fish. The water is warm and has a high salt content. The sea got its name because of the high occurrence of blue-green algae and the red rocks there, which are colored by iron oxide.
