10 Facts About Ice age

An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers.

Individual pulses of cold climate within an ice age are termed glacial periods, and intermittent warm periods within an ice age are called interglacials or interstadials.

In glaciology, ice age implies the presence of extensive ice sheets in both northern and southern hemispheres.

Ice age reported that the inhabitants of that valley attributed the dispersal of erratic boulders to the glaciers, saying that they had once extended much farther.

Ice age attempted to show that they originated from changes in Earth's orbit.

The Huronian ice age was caused by the elimination of atmospheric methane, a greenhouse gas, during the Great Oxygenation Event.

The ice age continues until the reduction in weathering causes an increase in the greenhouse effect.

The present ice age is the most studied and best understood, particularly the last 400, 000 years, since this is the period covered by ice cores that record atmospheric composition and proxies for temperature and ice volume.
