Question

what effect did the glaciers have on ancient humans during the last ice age? they caused the destruction of several civilizations due to rising sea levels. they forced ancient humans to abandon north america and migrate to south america. they influenced the cultures that developed in portions of north america. they created a land bridge that allowed humans to travel from asia to the americas.

Explanation:

• Option 1: Civilizations during the last ice age were not as developed as to be destroyed by rising sea levels from glaciers (the last ice age had glacial advance, not sea - level rise in the way to destroy civilizations).
• Option 2: There is no evidence that ancient humans abandoned North America to migrate to South America due to glaciers.
• Option 3: While glaciers may have some influence on culture, the most significant and well - known effect of glaciers during the last ice age on human migration was the creation of the Bering land bridge.
• Option 4: During the last ice age, the lowering of sea levels due to the formation of glaciers exposed the Bering land bridge (between Asia and North America), which allowed humans to migrate from Asia to the Americas.

Answer:

D. They created a land bridge that allowed humans to travel from Asia to the Americas.
