How did the formation of glaciers during the Ice Age allow for migration to North America?
The glaciers accumulated precipitation in the upper latitudes, and locked more of the evaporated sea water into permanent ice. This had the effect of slowly lowering sea levels during the Ice Ages.
The ocean in the Bering Strait is relatively shallow, and the sea floor was therefore above sea level for thousands of years, until the glaciers melted and returned water to the oceans. This land bridge allowed hunters to pursue prey that had migrated to the Americas.

During the ice age the bottom of Bering Strait became?
During the ice age, the bottom of the Bering Strait became exposed due to lowered sea levels caused by the formation of glaciers. This land bridge, known as Beringia, connected Asia and North America and facilitated the migration of humans and animals between the two continents.
What events led to the migration of Asian peoples into north America?
The formation of Beringia created during the ice age formed the basis for this migration, Asian peoples just followed the large migrating animals and then worked their ways east and south.
What events led to the migration of Asian peoples to north America?
The formation of Beringia created during the ice age formed the basis for this migration, Asian peoples just followed the large migrating animals and then worked their ways east and south.
Why are there more birds on one side of the V formation during migration?
During migration, birds fly in a V formation to conserve energy. The birds on one side of the V formation are typically more numerous because they benefit from reduced wind resistance and can take turns leading the flock.
What was the name of the land formation that allowed people to cross into america?
The land formation that allowed people to cross into America is known as the Bering Land Bridge. This land bridge connected Asia and North America during the last Ice Age when sea levels were lower, enabling migration of humans and animals. It played a crucial role in the peopling of the Americas.
Which continents was covered by glaciers during the Pleistocene ice age?
During the Pleistocene ice age, glaciers covered large parts of North America, Europe, and Asia. These glaciers were extensive and had a significant impact on the landscape and climate of these continents.
What was hard during the migration to north America from Asia?
because they love chiken
What percent of earth is covered by glaciers during of the ice age?
During the peak of the last ice age, approximately 30% of Earth's surface was covered by glaciers. These glaciers were part of massive ice sheets that extended over North America, Europe, and Asia.
How did glaciers affect north America during the last ice age?
During the last ice age, glaciers significantly shaped North America's landscape by carving out valleys, forming lakes, and creating features such as fjords and moraines. As they advanced, they also altered river systems and deposited sediments, which contributed to soil formation in various regions. The immense weight of the glaciers caused land subsidence, and their eventual retreat led to rising sea levels and ecological changes, paving the way for new habitats and species evolution. Overall, glaciers played a crucial role in sculpting the physical and environmental characteristics of the continent.
What continents did glaciers appear?
Glaciers have appeared on every continent except Australia. They have been particularly extensive in Antarctica, Greenland, North America, and Europe during past glaciations.
Why north America was covered in ice during several periods of time long ago?
The whole northern part of north america is not covered by glaciers.
How do birds decide who leads the V formation during migration?
Birds in a V formation during migration take turns leading the group. The bird at the front faces the most wind resistance, so it drops back and another bird takes its place. This rotation helps the group conserve energy and travel more efficiently.
