The Red Sea

Context: New geological research by KAUST scientists in Saudi Arabia has discovered that the Red Sea completely dried up for nearly 100,000 years about 6.2 million years ago before being refilled by a massive flood.

About The Red Sea:

• What It Is?

• The Red Sea is a narrow, elongated saltwater inlet of the Indian Ocean, located between northeastern Africa and the Arabian Peninsula. It is one of the world’s youngest seas, formed by the rifting of the African and Arabian tectonic plates around 30 million years ago.

• Located In:

• Extends south-eastward from Suez (Egypt) for about 1,200 miles (1,930 km) to the Bab el-Mandeb Strait, connecting to the Gulf of Aden and the Arabian Sea.

• Border Nations: Egypt, Sudan, Eritrea, Saudi Arabia, and Yemen.

• Key Features:

• Geological Origin: Lies within a rift valley, part of the East African Rift System, marking the separation of Africa and Arabia. Dimensions: Covers an area of ~450,000 sq km, with a maximum depth of 3,040 m (9,974 ft). Salinity and Temperature: One of the hottest and saltiest seas, due to high evaporation and minimal freshwater inflow. Marine Biodiversity: Home to extensive coral reefs, unique brine pools, and diverse marine ecosystems. Volcanic Activity: Hosts underwater volcanoes and geothermal features, evidence of ongoing tectonic movement.

• Significance:

• Strategic Maritime Route: Forms a vital link between Europe and Asia via the Suez Canal, carrying a large share of global maritime trade. Economic Importance: Supports major shipping, tourism, and fishing industries for bordering nations.
