Answer:
Explain how the ability to describe the pattern of ice ages over the past million years help to assess what is normal variation in the Earth's atmosphere
.
Explanation:
The description of the pattern of ice ages allows the study of climatic variations over the years. This helps to understand the normal variation in the earth's atmosphere, I understand the climate established in each season and how it influenced the patterns of life and resources in the pallet.
These descriptions are made using paleoclimatic instruments that observe elements such as the composition of the ice, the structure of the trees and possible fossils.

D) The causes aren't shown, but likely it's due to immigration quotas and restrictions set. These were laws aimed to reduce people coming into the country. For instance, the Immigration Act of 1907 was made when population numbers increased dramatically in large cities like New York (and things like crime and unemployment rates went up as well).

F) Immigrants came looking for better opportunities, better paying wages, higher standards of living, etc. Some fled from brutal dictators and/or war conditions in their home country. Ideally they would have preferred to stay home where they're most comfortable, but these factors were enough to get them to travel vast distances, deal with terrible hardships such as disease, just to have a chance at a better life. The economic factors deal specifically with money of course, but the other factors shouldn't be overlooked as well.
