What ocean is on the East Coast of the United States?

The Atlantic Ocean is the body of water that borders the East Coast of the United States. This ocean stretches from the northern states like Maine all the way down to Florida in the south. Its importance is significant for trade, tourism, and ecosystem diversity. The Atlantic is known for its rich maritime history, which includes the early exploration and colonization of America by European powers.

Other oceans, such as the Pacific Ocean, lie on the opposite side of the country, along the West Coast. The Indian Ocean is located to the south of Asia and does not have any direct geographical connection to the East Coast of the United States. The Arctic Ocean is situated at the polar region, north of the mainland United States and is not relevant when discussing the eastern seaboard. Thus, the Atlantic Ocean is the correct answer due to its geographic location adjacent to the East Coast.
