What are the major geologic events in the quaternary period?

Slight shifts caused frequent ice ages. Polar ice advanced and retreated each time, carving and moulding the land. A pattern of the Ice Ages emerged, but by the last Ice Age, the ice began to melt and the sea levels rose rapidly. Many ice land bridges were formed between continents.

There are not names for the major geologic events, but here are the names of some things created by the Ice Age shifts:

Beringia/Bering Land Bridge (between Asia and North America)

Doggerland (landmass connecting Great Britain to Europe)

Bering Straight Crossing (between Russia and Alaska)
