GENERAL GEOLOGY

Detailed explanation-1: -The various unsorted rock debris and sediment that is carried or later deposited by a glacier is called till.

Detailed explanation-2: -A general term applied to all rock material (clay, silt, sand, gravel, boulders) transported by a glacier and deposited directly by or from the ice, or by running water emanating from a glacier. This category is also used for Glacial sediment.

Detailed explanation-3: -A moraine is material left behind by a moving glacier. This material is usually soil and rock. Just as rivers carry along all sorts of debris and silt that eventually builds up to form deltas, glaciers transport all sorts of dirt and boulders that build up to form moraines.

Detailed explanation-4: -Later, when the glaciers retreated leaving behind their freight of crushed rock and sand (glacial drift), they created characteristic depositional landforms. Examples include glacial moraines, eskers, and kames.

Detailed explanation-5: -Eskers. An esker is a long, sinuous, snake-like ridge composed of stratified drift that forms beneath a stagnant glacier. As a stream flows below a stagnant ice pack, sediment falls to the bottom and builds into a long sinuous pile.
