* Till: This is unsorted, unstratified material directly deposited by a glacier. It can range in size from clay to boulders and often contains a mixture of rock types.

* Outwash: This is sorted and stratified material that has been transported and deposited by meltwater flowing from a glacier. Outwash deposits are typically found in front of glaciers and are characterized by gravel, sand, and silt.
