Final answer:
An ice age is a period of time characterized by the year-round coverage of large regions of land with ice and snow. The Pleistocene Ice Age occurred approximately 2.6 million years ago and lasted until about 11,700 years ago. During this ice age, glaciers advanced and retreated, impacting the Earth's climate and sea level.
Step-by-step explanation:
An ice age is a period of time in which large regions of land are covered year-round with ice and snow. The most recent ice age, known as the Pleistocene Ice Age, occurred from about 2.6 million years ago to about 11,700 years ago. During this time, glaciers advanced and retreated multiple times, shaping the Earth's landscape and causing significant changes in climate and sea level.
