The Land Bridge Theory & the First Americans
The Land Bridge Theory According to the Land Bridge Theory, Native Americans migrated from Asia to North America across the land bridge. • Experts believe this happened during the Ice Age.
The Land Bridge Theory During this time period, low temperatures caused large areas on Earth to freeze and form glaciers. These glaciers caused the level of the ocean water to drop.
The Land Bridge Theory The land that once was under water became exposed, creating a long land bridge that connected North America to Asia.
The Land Bridge Theory The land bridge formed between Asia and North America.
Today the land bridge is covered by water – the Bering Strait.
What is a Strait? A strait is a narrow channel of water connecting two bodies of land.
Why did they come? The Native Americans were nomads who Oh and by the way… followed big game across the Bering Strait. mastodons In this context, the word mammoths “game” means wild mammals or birds hunted for sport or saber-toothed food.cats

Let’s Review A narrow channel of water connecting two bodies of land is called a _______________. STRAIT
Let’s Review People who travel from place to place and take their shelters with them are called _____________. NOMADS
Let’s Review What is the name of the strait that the Native Americans crossed from Asia into North America? THE BERING STRAIT
Let’s Review What is the name of the time period when the Native Americans traveled from Asia to North America? ICE AGE
Let’s Review The pathway created by the frozen water in the Bering Strait is called a _______________. LAND BRIDGE
How did the land bridge affect the settlement of Native Americans? It is believed that the hunters followed the animals down across Alaska into Canada and then into the United States. Some people broke off from the other groups when they saw an area where they wanted to stay.
