Answer:
a. The process of particles settling to the bottom of a body of water is called sedimentation. ... Layers of sediment in rocks from past sedimentation show the action of currents, reveal fossils, and give evidence of human activity
b. Sediment is the little bits of solids that sink to the bottom of a container of liquid, whether that container is a body of water or a holding tank at a sewage treatment plant.
c. "supernatant liquid" which means a liquid that comes to the top of a mixture and rests on the surface.
d. Settling down of heavier insoluble particles/ solids from a mixture is called sedimentation. Like mud settles from muddy water. Decantation is pouring out of upper clear layer of liquid into another container to separate two immiscible liquids

2)sediment=matter that settles to the bottom of a liquid; dregs.
3)supernant liquid =the usually clear liquid overlying material deposited by settling, precipitation, or centrifugation.
4)Decantation=Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension.
