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.
They changed from following a policy of Isolationism to becoming a superpower on the world stage
Well since the u-boats took out many allied patrols and shipments it made it harder for the allies to ship goods to England and other allies in the time of need....
Answer:
Nonviolent resistance could succeed in ending segregation is the right answer
Explanation:
A 13 month mass protest of bus boycott in the year 1955 with the arrest of Rosa Park in USA is known as the Montgomery Bus Boycott. In the leadership of Martin Luther, the boycott is an example of successful abolishing of segregation through nonviolent protest. This protest led the Supreme Court’s decision on un-constitutionalism of public buses.
It gained support outside the Montgomery. With the end of the boycott the segregated sitting in buses were removed by the laws of the Supreme Court.
