Why might the eastern section of the united states and canada experince higher levels of acid rain than the extreme northen and western sections of the region?

Maybe because winds flow west to east and also because many major city’s are along the west coast. And it rains more

It is the doctrine that the us had the right and duty to expand throughout north america. it just means they believed they had the right to expand westward and they did! they stated with the 13 colonies and then they kept moving gaining different territories throughout the years
