(a) Sedimentation
(b) decantation​

Answer 1

Answer:

a)when the heavier components in a mixture settles that process is called sedimentation

b)the process of removal of water above the sediment is called decantation

Explanation:

thats it I guess

Answer 2

Answer:

1st = Sedimentation is the tendency for particles in suspension to settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or electromagnetism.

2nd = Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. The layer closer to the top of the container—the less dense of the two liquids, or the liquid from which the precipitate or sediment has settled out—is poured off, leaving the other component or the more dense liquid of the mixture behind. An incomplete separation is witnessed during the separation of two immiscible liquids.To put it in a simple way decantation is separating an immiscible solution by transferring the top layer of the solution to another container.
