The Red Sea is a small part of the Indian Ocean. The Bab el Mandeb strait and the Gulf of Aden connect this inlet to the Indian Ocean. It is located between Africa and Asia. On its eastern side, it borders Saudi Arabia, Yemen, Jordan, Israel and on the western side, Eritrea, Egypt, Sudan and Djibouti. It has various names including Gulf of Arabia and the Erythrean Sea.

History of the Red Sea: –

Because of its beauty and marine biodiversity, its northern section has been named as one of the seven wonders of the underwater world. This sea was formed when Arabia split from the Northern Africa by Red Sea Rift.

This rift started 34 to 56 million years ago and increased its pace 23 to 34 million years ago. The land on either side reaches heights of more than 6,560 feet above sea level. This complex rift system includes the East African Rift System.


Early Exploration: –

Ancient Egyptians were the first to explore the Red Sea between 2500 BCE and 1500 BCE. They attempted to establish commercial routes to Punt. During the medieval times, it was an important part of the spice trade route.

This sea evaporated completely and the Bab el Mandeb strait closed down during the Tertiary period.

Measurements: –

It is measured 2,250 kilometers in length and 355 kilometers in width at its widest point. With a total surface area of 438,000 square kilometers, it holds approximately 233,000 cubic kilometers of water. The average depth of the Red sea is 490 meters and at Suakin Trough which is its deepest point, it is measured 3,040 meters.

Crossing the Red Sea: –

There is a famous story in the Bible which tells how Moses approached the Red Sea in 1250 BC when he was leading the Israelites in a daring escape from the Egyptian Army. He was a Pharaoh chosen by God to help Israelites out from slavery in Egypt. At that time, God separated the Red Sea so that Israelites can go safely on dry land. Once they all safely reached there, the sea crashed back, trapping and killing all the Egyptians.
