The Atlantic coast is home to some of the world's most important cities, including New York City, Boston, Philadelphia, and Miami. These cities grew in importance because of their role in trade.
The Atlantic Ocean is a major trade route, and cities located on the coast had a significant advantage in accessing this route. They could import goods from all over the world, and they could also export their own goods to other countries.
In addition, the Atlantic coast is home to many natural resources, such as fish, timber, and coal. These resources were essential for the development of the United States, and cities located on the coast had easy access to them.
As a result of these factors, cities along the Atlantic coast grew in importance and became major economic centers.
