What is the difference between Ocean and Sea? Answer: All of the above

he main difference between an ocean and a sea lies in size, depth, and location: • Oceans are vast, deep bodies of saltwater that cover about 71% of Earth’s surface (e.g., Pacific Ocean, Atlantic Ocean). • Seas are smaller parts of oceans, usually partially enclosed by land (e.g., Arabian Sea, Mediterranean Sea). Thus, every sea is part of an ocean, but not every ocean is a sea.
