Rock composition and measuring the seismic waves provide knowledge for the scientists to study the interior of the earth.
Explanation:
When the crust gets distributed it is easy to study the layers of the different materials that got settled and compacted in the earth. Patterns that are formed in the rocks provides to be a good source to know about the earth's crust. rock cores are cylindrical sections which are cut and removed from the earth crust for research purposes.
It is impossible to drill to the center of the earth and so scientists rely on seismic waves and the speed of the seismic waves depends on the material on which it is passing through. The toughness and stiffness obstruct the speed of the waves which is a means for the scientists to undertake research on the substance which hampered the speed of the seismic waves. P-waves, or pressure waves, which go through both liquids and solids, and S-waves, or shear waves which go through solids but not liquids. This provides the best data to undertake research regarding the earth' crust by the scientists.
Isolation and quarantine are public health practices used to protect the public by preventing exposure to people who have or may have a contagious disease.
Isolation separates sick people with a contagious disease from people who are not sick.
Quarantine separates and restricts the movement of people who were exposed to a contagious disease to see if they become sick. These people may have been exposed to a disease and do not know it, or they may have the disease but do not show symptoms.
