Ocean vs. Bay: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 13, 2023
"An ocean is a vast and expansive body of saltwater, while a bay is a smaller, partially enclosed area within an ocean or sea, often sheltered by land."

Key Differences

Oceans are immense bodies of saltwater, covering a major part of the Earth's surface. Bays, in contrast, are smaller bodies of water, partially enclosed by land and connected to an ocean.
