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.

Answer: "The condition of the people of America is so different from aught that we in Europe have an opportunity of observing... They are great travellers, and in general better acquainted with the vast expanse of country, spreading over their eighteen states... than the English with their little island. They are also a migrating people, and even when in prosperous circumstances, can contemplate a change of situation, which under our old establishments and fixed habits, none, but the enterprising, would venture upon, when urged by adversity."
