How does the Mozambique Channel separate mainland Africa from Madagascar?

The Mozambique Channel is a significant body of water in the western Indian Ocean that separates the island country of Madagascar to the east from Mozambique on the African mainland to the west.1

Spanning approximately 1,000 miles (1,600 km) in length, the channel varies in width from 250 to 600 miles (400 to 950 km) and reaches depths of up to 10,000 feet (3,000 meters). The strait serves as a vital shipping route for eastern Africa and is characterized by the flow of the Mozambique Current, which influences the climate of both the mainland and the island. The northern entrance is marked by the Comoro Archipelago, while the southern region contains the islands of Bassas da India and Europa.123
