Tracts of water-sorted glacio-fluvial soils are often intermixed with till soils. Figure 16.29 illustrates some of the ways that sediments are transported and deposited. Ablation till: let down as the glacier melts. When the glacier moves away it may then be broken off. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Another type of erosion is terminal moraine) 3. Moreover, ice slurries are applicable for heavy thermal loads because they have high melting heat transfer rate.

Lodgement till is material deposited by moving ice such as ground moraine which is dropped by the glacier when its weight becomes too heavy to move. Lodgement till is laid down subglacially when debris is released directly from the sole of the ice. In situations where a glacier is receding, a block of ice might become separated from the main ice sheet and become buried in glaciofluvial sediments. Frost wedging is the process that happens when water fills a crack in the rock, then freezes, and then expands. Flow till: from flow of supra glacial substance at the ice front.
