An ablation till implies thin, slow moving or stagnant ice which was melting downward, depositing its sur ficial and englacial load of sediment. Tillage also reduces crop residue, which help cushion the force of pounding raindrops. fH#q2Z~lOgSJ:0gB%Ys&GLt#a3Tg:$d!t"Lfb%"T!00P`0 g&'g!h&aB3 Ba< Sa Processes of glacial deposition The main processes are as follows: 1.

Flint ( 1957, p. 121) refers to the basal drift (ground moraine) as "lodgment till" to emphasize that it comes to rest more or less in place where the ice stagnates. Most glacial depositional landforms are of this type. y.) It blankets glacier forefields, can be mounded to form moraines and other glacier landforms, and is ubiquitous in glacial environments.

Icebergs are common on proglacial lakes, and most of them contain englacial sediments of various sizes. The latter references materials deposited by glacial meltwater. If accumulation exceeds ablation the glacier will grow. (1) combined processes (such as sublimation, fusion or melting, evaporation) which remove snow or ice from the surface of a glacier or from a snow-field; also used to express the quantity lost by these processes (2) reduction of the water equivalent of a snow cover by melting, evaporation, wind and avalanches. an outwash plain), and within that area, glaciofluvial deposits can be tens of metres thick. A good rule of thumb is to keep at least $20 in five-dollar bills and $20 in one-dollar bills.
