The map shows where the Bering land bridge once existed.

Question

A map titled Area of the Bering Land Bridge. A key shows Land with present-day coastlines in dark green and Land exposed during the last ice age due to lower sea levels in green. Green surrounds the coast of Northeast Russia and Alaska, USA and an area between those two areas.

Which statement does the map support?

Humans from North America crossed the Bering land bridge to follow animal herds.
The Bering land bridge connected the Arctic Ocean and the Pacific Ocean.
The Bering land bridge was hundreds of miles wide at its narrowest spot.
North America was cut off from Asia when rising sea levels covered the Bering land bridge.

Answer 1

The statement that the map supports is:

North America was cut off from Asia when rising sea levels covered the Bering land bridge.

This conclusion is based on the representation of the Bering land bridge on the map, indicating the areas that were connected during the last ice age and illustrating how rising sea levels later submerged this land connection, effectively separating North America from Asia.
