Straits And Channels Challenge – Choke Points of the World

A strait is a narrow natural waterway connecting two larger bodies of water. Because ships must squeeze through, straits such as Hormuz, Malacca, Gibraltar and the Bosphorus are called choke points, and controlling them has shaped wars and trade for centuries.

Some straits also link continents. The Bering Strait was once a land bridge that early people crossed from Asia to the Americas, and the Bosphorus has been crossed by bridges and tunnels connecting Europe and Asia.
