What Are Glaciers? Crash Course Geography #26



Today we’re going to talk about glaciers. These behemoth globs of compressed ice and snow moving across the land created fertile soils and physical features while also serving as frozen time capsules. They recorded both Earth’s climatic history over several million years and contain clues to its climatic future. By now we hope it’s become clear that the Earth is ever-changing, and glaciers have often been a crucial part of that change from the erratic boulders found in New York City’s Central Park to the beautiful spire of the Matterhorn in the Alps on the border of the Italy and Switzerland.
