Glacial till is a type of sediment that is deposited directly by a glacier. It consists of a mixture of clay, silt, sand, gravel, and boulders, which are all carried along by the moving ice. When the glacier melts, it releases this material, creating a varied landscape of unsorted debris. This sediment can be found in areas previously covered by glaciers, such as parts of North America and Scandinavia. Glacial till plays a significant role in shaping the land and can influence soil fertility, making it important for agriculture and natural ecosystems.
