Glacial Stratigraphy

Glacial stratigraphy is the study of layered sediments and rocks formed by glaciers. As glaciers move, they pick up and deposit materials like sand, gravel, and dirt, creating distinct layers. These layers, called tills and varves, record the history of glacial activity over time. By examining their composition, sequence, and features, geologists can reconstruct past ice movements, climate patterns, and environmental changes during the Ice Age. This study helps us understand how glaciers shaped the landscape and provides insights into Earth's climatic history.
