A. they gain new legal rights

Explanation:

As a result of the American Civil War, African Americans gained freedom from slavery in all states that had been allowing slavery. The newfound freedom meant that they were now free American and could apply for jobs they wanted instead of jobs that their masters chose for them.

Being able to do their own jobs, they were able to make an income which goes a long way in economic emancipation. Even though they now had legal rights, it took several decades for them to be treated equally in work places due to the Civil Rights movements of the 20th century.

according to hess's theory, when the magma cooled, it would expand and push the tectonic plates apart. it would push the north and south america plates to the west and eurasia and africa ones to the east. the atlantic ocean would get wider but the coastlines of the masses would stay the same.

harry hammond hess was a geologist and a united states navy officer in the second world war. he is considered to be one of the founding fathers of the theory of plate tectonics. he is known for his theories on sea floor spreading, stating that the movement of the continents was the result of see floor spreading. the continents are attached to the plates and do not move separately. the plates themselves shift and change shape, carrying the continents along.
