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

The Pacific Ocean is the correct answer because it is the largest and deepest ocean in the world and lies along the entire west coast of the United States. States like California, Oregon, and Washington have coastlines that directly border the Pacific Ocean, making it a significant geographical feature of the region. The Pacific Ocean plays an important role in trade, climate, and marine biodiversity for the west coast.

In contrast, the Atlantic Ocean is situated on the east coast of the United States, while the Indian Ocean is primarily located to the south of Asia and southwest of Australia, making it unrelated to the geography of the continental United States. The Arctic Ocean, positioned to the north of North America, also does not impact the west coast. Thus, the Pacific Ocean is the only option that accurately reflects the ocean situated along the west coast of the United States.
