🧊 The World Under Ice
That ice sheet disappeared roughly 10,000 years ago as the climate warmed at the end of the last Ice Age. But the landscape it carved is still here. The dramatic U-shaped valleys of the Lake District. The jagged arêtes of Snowdonia. The ribbon lakes of Scotland. The flat till plains of the English Midlands. Every one of these features is the product of glacial processes — erosion, transport, and deposition carried out over tens of thousands of years. Understanding these processes is not just academic: it is the key to reading the entire British landscape, and to understanding why glacial environments look and behave as they do anywhere on Earth.
Right now, glaciers cover roughly 10% of Earth's land surface. As the climate warms, almost all of them are retreating — and the same processes that shaped Britain's past are playing out today in the Alps, the Himalayas, Greenland, and Antarctica. This topic explains exactly how they work.
