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.

What is the other key factor influencing glacial formation?
Climate is the other key factor influencing glacial formation. Glaciers form in areas where the climate is cold enough to allow snow and ice to accumulate over time, usually at high latitudes or high elevations. The accumulation of snow and ice, combined with the right temperature conditions, allows glaciers to grow and move over the landscape.
Where are glaciers found in Alaska and why are they located there?
In the Sounthcentral and Southeastern mountains of the state, as there is enough moisture and cold temperatures to allow glaciers to survive.
Why are there no glaciers in the blue ridge mountains?
The Blue Ridge Mountains lack glaciers primarily due to their relatively mild climate and lower elevation compared to other mountain ranges. Glaciers form in areas where temperatures remain consistently cold enough to allow for the accumulation and compaction of snow over time, which is not typical for this region. Additionally, the Blue Ridge Mountains are located in the southeastern United States, where warmer temperatures and seasonal rainfall do not support the conditions necessary for glacier formation.
What did America's neutrality during the Spanish civil war of 1936-1939 allow?
Spain to become a fascist dictatorship.
What part of the earth is composed of glaciers and frozen polar caps?
Glaciers and frozen polar caps are found in the polar regions of Earth, specifically in Greenland and Antarctica. These areas have extremely cold temperatures that allow ice to accumulate and form large ice sheets and glaciers.
What conditions must exist for a glacier to form?
Glaciers form when snow accumulates and compacts over time into dense ice. This process requires specific environmental conditions such as cold temperatures that allow the snow to persist without melting, as well as a consistent snowfall rate that exceeds melting and sublimation. Topography, such as high elevations or polar regions, also plays a role in glacier formation by providing a location where snow can build up and eventually transform into ice.
How did the ice age influence human migration into north America?
During the many warm, (interglacial), periods in the present ice age it would have been impossible for humans to travel from Asia to North America. Only during glaciations would sea level drop enough to allow migrations from one continent to the other on dry land across, what is now, the Bering Strait.
What is the answer for glaciers pick up rocks by a proses is called?
The process by which glaciers pick up rocks is called "glacial plucking." As glaciers move, they exert pressure on the underlying bedrock, causing fractures that allow them to pull away pieces of rock. This process contributes to the erosion and shaping of the landscape as the glacier transports the debris.
Cb you relate the movement of continental glaciers to why they cover Antarctica and most of Greenland?
Continental glaciers, or ice sheets, form in regions where snowfall exceeds melting and sublimation over long periods. Antarctica and most of Greenland are situated in polar climates, where low temperatures promote the accumulation of snow and prevent significant melt. The vast land areas and high elevations in these regions allow for the thick buildup of ice, leading to the formation of extensive ice sheets that cover the majority of their surfaces.
