Question

What is meant by Sedimentation and Decantation?

Answer 1

Hint: When the sand is mixed in water, then the sand settles down and water gets separated, and then water is transferred to another beaker or container without the sand coming in the second beaker. This process contains the first sedimentation and then the decantation.

Complete answer:
Let us know first about sedimentation, when we mix something in the water which cannot be dissolved in water like sand, stone, gravel, etc, will settle down and the water will remain as the top layer. This process is known as sedimentation.
Now, let us discuss the decantation process when we separate the layer of water or any liquid when a heavier thing settles down but transferring the water or liquid to another container. This process is known as decantation.

Note:
When we use any separating device or thing like filter paper, then the process is known as filtration. Filtration is a process when water and the sand are separated using a filter paper.
