There are several names: outwash is one and moraines are another. The outwash forms a flat area sometimes called outwash planes and the moraines are hilly.
All sediment resulting from glaciation is known as 'drift'. This can be subdivided into till, which is material deposited directly by the ice, and outwash, which is material deposited by meltwater from the glacier. Examples: Moraine, drumlins, erratics, ice-transported boulders.

A rock is a mineral matter of variable composition, assembled in masses or considerable quantities by nature, as by heat or water. A sediment is a rock that is weathered down by wind, water, or glacial ice. Reference: dictionary.com

Deposition
The debris of boulders eroded and carried down by glaciers will eventually form moraines (mounds) where the front of the glacier melts and retreats, leaving the debris behind. Moraines can be high and wide enough to form a dam, behind which glacial melt water is trapped and lakes are formed.

Quick clay would be one phase, where the material is very fine, saturated with liquid, and prone to liquefaction.Varves would be another (word derived from the Scandinavian for wave), and presents as well-layered fine silt on the bed of a glacier fed lake. Probably a seasonal process, with a graded particle size.Outwash Gravels are a little more remote from the glacier, and are generally re-mobilized moraine materials. These will show a dendritic pattern of the streams that formed the deposit.
When sediment is laid down, this is known as deposition. The sediment is unconsolidated and so it is not (yet) a rock.

We use the term deposition to describe the process by which sediment is laid down in a body of water. The sediment is said to have been deposited at the bottom of the body of water, and more may follow to build a layer of sediment.
