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

The Pacific Ocean is the largest and deepest ocean in the world, and it lies along the entire West Coast of the United States. Spanning from the northern to the southern borders, the Pacific Ocean plays a significant role in the climate, ecology, and economy of the coastal states, including California, Oregon, and Washington. Its vast expanse affects weather patterns and supports diverse marine ecosystems, as well as industry sectors such as fishing and tourism.

To add context, the Atlantic Ocean is located on the East Coast of the United States, while the Indian Ocean and Arctic Ocean are situated far from the U.S. mainland and do not border any U.S. states. This geographical detail reinforces the importance of recognizing the Pacific Ocean as the ocean located on the West Coast of the United States.
