The hunter-gatherer way of life made it impossible for people to live. a) in groups. b) in cold climates. c) in permanent dwellings. d) without a spoken language..

The correct answer is C) in permanent dwellings.

The hunter-gatherer way of life revolved around a groups ability to hunt down prey ( the type of prey depended on the group/time period). These groups would hunt and gather in a particular area as much as possible until the prey was no longer available there. When this happened, groups would move out of the area in order to find the prey. This meant that groups were on the move quite often, otherwise they would be unable to live. This is because the prey they hunted provided almost their entire food supply.

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.
