Explanation:
Detailed explanation-1: -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-2: -The Last Glacial Maximum (LGM) occurred about 20, 000 years ago, during the last phase of the Pleistocene epoch. At that time, global sea level was more than 400 feet lower than it is today, and glaciers covered approximately: 8% of Earth’s surface. 25% of Earth’s land area.
