The two types of glacial drift are till, which is unsorted sediment deposited directly by the ice, and stratified drift, which is sorted sediment deposited by glacial meltwater.
Glacial till is unsorted and unstratified sediment deposited directly by a glacier, while stratified drift is sorted and stratified sediment deposited by glacial meltwater. An example of glacial till is a moraine, which is a ridge of mixed debris left behind by a moving glacier. An example of stratified drift is an outwash plain, which is a flat, gently sloping area formed by the deposition of sorted sediments carried by glacial meltwater.
Glacial drift refers to the material, such as rocks, sand, and clay, that is carried and deposited by glaciers as they move across the land. It includes both till, which is material directly deposited by the glacier, and stratified drift, which is material sorted and deposited by meltwater from the glacier. Glacial drift plays a crucial role in shaping the landscape and can be used by geologists to understand past glacial activity.
No
Till or glacial till is unsorted glacial sediment. Glacial drift is a general term for the coarsely graded and extremely heterogeneous sediments of glacial origin.Glacial till is that part of glacial drift which was deposited directly by the glacier.Its content may vary from clays to mixtures of clay, sand, gravel and boulders. This material is mostly derived from the subglacial erosion and entrainment by the moving ice of the glaciers of previously available unconsolidated sediments.A glacier is a large persistent body of ice that forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.
drift
Sediments directly deposited by the glacier are called till.
Drift and/or till.
The two main types of glacial drift are till and moraine. Till refers to the mixture of sediments deposited directly by the ice, while moraine refers to the accumulation of till along the edges or underneath a glacier.
