What strait separates Asia from North America at its narrowest point (about 82 km)?

The strait separating Asia from North America at its narrowest point, about 82 kilometers wide, is the Bering Strait.

It lies between Russia's Chukchi Peninsula and Alaska's Seward Peninsula, linking the Arctic Ocean's Chukchi Sea with the Pacific Ocean's Bering Sea. At its narrowest point, Cape Dezhnev in Russia is about 82 kilometers from Cape Prince of Wales in Alaska.

The strait is named for Vitus Bering, the Danish-born explorer who sailed for Russia. Its shallow waters became especially important during the Ice Age, when lower sea levels exposed Beringia, a broad land bridge connecting Siberia and Alaska. Scientists believe ancient peoples used this region during the peopling of the Americas, although the timing and routes remain subjects of research.

The Bering Strait is often confused with the Strait of Magellan, which separates mainland South America from Tierra del Fuego. Cook Strait is in New Zealand, while Torres Strait lies between Australia and New Guinea.
