Geography and Geology

The Red Sea is approximately 1,900 kilometers (1,200 mi) long and 355 kilometers (220 mi) wide at its widest point. It is one of the saltiest bodies of water in the world, with an average salinity of 4.1%. The Red Sea is considered a young sea, formed about 30 million years ago due to tectonic plate movements that created a rift valley. This ongoing geological activity is evident in the numerous volcanic islands and hydrothermal vents found in the sea. The Red Sea is connected to the Indian Ocean through the narrow Bab-el-Mandeb strait.
