What happens during centrifugation to form a pellet and an supernatant?

Here, particles are concentrated as a pellet at the bottom of the centrifuge tube and separated from the remaining solution, called supernatant.
What is the process of removing the supernatant called?
The supernatant can be removed by either decanting it – a fancy name for pouring it off, or it can be aspirated – a fancy term for using suction to remove it. The purified specimen can then be returned to a solution via a process called, resuspending.

What does it mean to decant a supernatant?

In this method, filtration of the supernatant and washing of the precipitate are also occasionally necessary. This operation is repeated a few times to wash the precipitate.
How are supernatant and pellet different?
As nouns the difference between pellet and supernatant is that pellet is a small, compressed, hard chunk of matter while supernatant is the liquid that lies above a sediment or precipitate; supernate.
Is DNA in the pellet or supernatant?
