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

The correct answer is the Atlantic Ocean, as it borders the East Coast of the United States. The Atlantic Ocean serves as a significant geographical boundary and is crucial for trade, transportation, and cultural exchange. It is the ocean that runs alongside states such as Florida, New York, and Maine, providing them with access to maritime activities and resources. The Atlantic Ocean has historically played a vital role in U.S. history, influencing exploration, colonization, and the development of the nation as a whole. The other oceans listed do not touch the East Coast; the Pacific Ocean lies on the West Coast, while the Indian and Southern Oceans are located far from the U.S. mainland.
