What do sedimentation and centrifuge have in common? Well when you are looking to get a degree in geology, they are two very important processes. But more relevantly here, they both have a lot to do with the topic at hand: sedimentation and centrifugation. In the following article we will be looking at these two processes, examining how they work and learning more about each one individually.
