The strait that separates Asia from North America is the Bering Strait. This narrow waterway connects the Chukchi Sea in the Arctic Ocean to the Bering Sea in the Pacific Ocean, with the Russian landmass of Siberia on one side and Alaska on the other. The Bering Strait is historically significant, as it is believed that ancient peoples migrated from Asia to North America across a land bridge known as Beringia during the last ice age. The strait is also vital for navigation and marine biodiversity.
