The correct answer is "the North, South, and West had differing economic and political goals."
The main reason for sectional differences that existed in the United States in the early 1800s was that the North, South, and West had differing economic and political goals.
Indeed, it was a time of notorious divisions and sectorial differences between the North and the South of the United States.
At that time, there were 22 states considered from the North, and 11 from the South. The northern states were against segregation, while southern states supported slavery. Indeed, the economy of the southern states depended on the use of slaves to work in the large plantations producing the kinds of crops needed to be exported to Europe. On the other hand, the industries flourished and spread throughout the north. The DIfference increased to the degree of separation. The South ceded from the Union and formed the Confederate States, and then, the inevitable: the beginning of the American Civil War.
The correct answer is: An Epeirogenic change occurs when rock layers are lifted out of sequence.
The epeirogenic movements are the vertical rise and fall movements slowly produced in the Earth's crust. For centuries, diverse movements in the Earth's crust had been produced, due to the pression it receives from the internal layers of Earth. This movements generated multiple changes i the cortex or crust. Epeirogenic movements ara capable of modeling the environment without cracking or breaking it. This movements are produced in the tectonic plates creating irregularities in the terrain in a slowly but progressive way.
When this movements are descendant or negative, part of the continental shields remain immersed, leading to the formation of seas slightly deep and to the formation of the continental platforms; sedimentary layers remain into the most antique igneous or metamorphic rocks. When the movements are ascendant or positive, the sedimentary layers are placed above the sea level being exposed to erosion. The effects of the epeirogenic movement are observed in the change of the coastal lines and the progressive transformation of a continent's aspect.
