What was the main concern was excluding slaves from the american revolutionary war effort

The major concern about the integration of slaves into the american revolutionary war was that the british forces could increase amazingly.

Explanation:

First of all, let's analyze the context and after that see why our answer is correct. In the American revolutionary war, the major belief was that if the revolutionary forces included slaves into their ranks. Thee English would also do that. And that was a considerable turning point to not do it. First of all, because the English didn't only have the thirteen colonies in America, but all over the world. So their power to gather slave forces would have been amazingly advantageous for them against the American revolutionary forces. And thinking about it, it still would represent a concern.

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.
