What is ice age?

Question

What is ice age?

Answer 1

The time when most of the world was covered by ice. There were four major glaciation time intervals from late Proterozoic to the Quaternary.

Answer 2

An ice age is a period of long-term reduction in the temperature of Earth's climate, resulting in an expansion of the continental ice sheets, polar ice sheets and mountain glaciers ("glaciation").

Glaciologically, ice age is often used to mean a period of ice sheets in the northern and southern hemispheres; by this definition we are still in an ice age (because the Greenland and Antarctic ice sheets still exist).

More colloquially, when speaking of the last few million years, ice age is used to refer to colder periods with extensive ice sheets over the North American and Eurasian continents: in this sense, the most recent ice age ended about 10,000 years ago.

Answer 3

it is a movie and a theory that the dinosours were whiped out by an giant meteor that through off the seasons and caused the entire world to be frozen for many years and killed off most living things.

Answer 4

A cold period marked by episodes of extensive glaciation alternating with episodes of relative warmth.

Ice Age The most recent glacial period, which occurred during the Pleistocene Epoch (The period of Prehistory between 35,000 and 12,000 years ago, when huge ice sheets covered much of northern Europe and North America).

Answer 5

It is a time when all of the ice caps melted enough to cause ocean currents to change and freeze the planet into a ice world.
