An ice age is a long period of reduction in the temperature of the Earth's surface and atmosphere. Ice Age may also refer to:

Mar 11, 2015 · Scientists have recorded five significant ice ages throughout the Earth’s history: the Huronian (2.4-2.1 billion years ago), Cryogenian (850-635 million years ago), Andean-Saharan (460-430...

Jan 10, 2025 · Ice age, any geologic period during which thick ice sheets cover vast areas of land. Such periods of large-scale glaciation may last several million years and drastically reshape surface features of entire continents. A number of major …

May 24, 2017 · An ice age is a period in which the earth's climate is colder than normal, with ice sheets capping the poles and glaciers dominating higher altitudes. Within an ice age, there are varying pulses of colder and warmer climatic conditions, known as 'glacials' and 'interglacials'.

Feb 3, 2021 · Periodically, global temperatures drop, ice sheets form at the poles, then the ice creeps down to cover the continents. We call these ice ages. There have been five major ice ages in Earth’s 4.5-billion-year history.

The Pleistocene (/ ˈ p l aɪ s t ə ˌ s iː n,-s t oʊ-/ PLY-stə-seen, -⁠stoh-; [4] [5] referred to colloquially as the Ice Age) is the geological epoch that lasted from c. 2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the ...

May 15, 2023 · An Ice Age, also known as a glacial age, happens when Earth's surface and atmospheric temperatures remain low for an extended period, stretching over millions of years. This results in changes to the Earth, including the expansion of continental ice sheets, polar ice sheets, and alpine glaciers.

An ice age is a period of cooling, marked by the presence of glaciers and ice sheets. Learn how an ice age works and if we're in an ice age right now.
