stratified drift ;D
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.
The process is called deposition.
Erosion is the moving of sediment from one place to another place. Deposition is the settling of particles suspended in air, ice, or water due to gravity or friction.
Glacial PlainA l outwash plain is a stratified deposit of sand and gravel transported by water from a melting glacial ice sheet.

When sediment is laid down, this is known as deposition. The sediment is unconsolidated and so it is not (yet) a rock.

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.
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.
bcuz of the gravity
Erosion is a wearing away process, which is what creates the sediment in the first place, but when sediment is laid down in a new location, that is not erosion, it's sedimentation.
Isn't it, " Why are very FEW fossils found in rocks made from sediment that laid down in deep ocean waters?"and i thought you would know.
Sedimentary rock formations are those which are formed by layer upon layer of sediment being laid down by natural forces. It is the stone in which history is hidden.
First of all there is weathering (erosion) of rocks at some place, they are carried away by wind or water at some other place and deposited there.Layers on layers are deposited to form sediments.
