Morainic

Morainic refers to material deposited by a glacier. This material, known as till, is unsorted and unstrathesized, meaning it consists of a mixture of clay, silt, sand, gravel, and boulders of various sizes. When glaciers advance, they pick up and transport this debris. As the glacier melts and retreats, it leaves behind the accumulated till. This deposited material forms distinct landforms called moraines.

There are several types of moraines, each named for its location relative to the glacier. Terminal moraines are formed at the furthest extent of a glacier's advance. Recessional moraines are deposited as a glacier temporarily pauses during its retreat. Lateral moraines are found along the sides of a glacier, and medial moraines are formed where two glaciers merge, with their lateral moraines joining in the middle. These morainic deposits significantly shape the landscape, creating hills, ridges, and depressions that can influence drainage patterns and soil characteristics. The study of morainic features is a key aspect of glacial geology and geomorphology.
