In the context of U.S. geography, which of the following is NOT an ocean?

The Red Sea is not classified as an ocean; instead, it is a sea that lies between the northeastern coast of Africa and the Arabian Peninsula. The distinction between oceans and seas is important in geography. Oceans are larger bodies of saltwater that cover significant portions of the Earth's surface, while seas are smaller and partially enclosed by land.

In contrast, the Atlantic, Pacific, and Indian Oceans are all major oceans that span thousands of miles and play significant roles in global climate, weather patterns, and marine biodiversity. Understanding these classifications aids in comprehending the larger geological and environmental frameworks of our planet.
