Detailed explanation-1: -long period of cold climate where glaciers cover large parts of the Earth. The last ice age peaked about 20, 000 years ago. Also called glacial age. having to do with the North and/or South Pole.
Detailed explanation-2: -An ice age is a period of colder global temperatures and recurring glacial expansion capable of lasting hundreds of millions of years.
Detailed explanation-3: -The Ice Ages began 2.4 million years ago and lasted until 11, 500 years ago. During this time, the earth’s climate repeatedly changed between very cold periods, during which glaciers covered large parts of the world (see map below), and very warm periods during which many of the glaciers melted.
Detailed explanation-4: -During the most recent glacial maximum (stadial, 23, 000 to 11, 000 years ago), the average global temperature was about 8℃, with polar regions experiencing average temperatures of-2℃. Ice-free periods over the past 500 million years correspond with average global temperatures of over 20℃.
Detailed explanation-5: -Within an ice age are multiple shorter-term periods of warmer temperatures when glaciers retreat (called interglacials or interglacial cycles) and colder temperatures when glaciers advance (called glacials or glacial cycles).
