How did the geography of ancient Greece contribute to the development of their civilization?(in paragraph form)

Answers

Answer:

Explanation:

The geography of the region helped to shape the government and culture of the Ancient Greeks. Geographical formations including mountains, seas, and islands formed natural barriers between the Greek city-states and forced the Greeks to settle along the coast.

Greece's steep mountains and surrounding seas forced Greeks to settle in isolated communities. Travel by land was hard, and sea voyages were hazardous. Most ancient Greeks farmed, but good land and water were scarce. Many ancient Greeks sailed across the sea to found colonies that helped spread Greek culture.

According to Clay, what was the only reason Jackson was elected President?
A. Jackson's personal experience in killing 2,500 Englishmen
B. Jackson's experience as chief magistrate C. Jackson's leadership in the Battle of New Orleans during the War of 1812​

Answers

Answer:

The correct answer is C

Explanation:

Jackson's leadership in the battle of New Orleans during the war of 1812

According to Clay, Jackson's leadership in the Battle of New Orleans during the War of 1812​ was the only reason Jackson was elected President. Thus, option (c) is correct.

What is Andrew Jackson?

On March 15, 1767, Andrew Jackson was born; he passed away on June 8, 1845. He was to stand in for the "corrupt bargain" that, in his opinion, cost him the presidency and gave him the drive to win the next election no matter what. Both the presidency and a job in John Quincy Adam's government were stolen from him.

General Andrew Jackson led his men into enemy territory to victory in numerous pivotal battles during the War of 1812. In doing so, he significantly contributed to our country's triumph in the war. During the Indian Wars, part of the War of 1812, he returned to military action as Major General of Tennessee Militia.

As a result, the Jackson's leadership in the Battle of New Orleans during the War of 1812​ was the only reason Jackson was elected President. Therefore, option (c) is correct.
