different between sea and ocean

A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, "the sea" is the interconnected system of Earth's salty, oceanic waters—considered as one global ocean or as several principal oceanic divisions.

noun: ocean; plural noun: oceansa very large expanse of sea, in particular each of the main areas into which the sea is divided geographically.

It would be really helpful if "vicky" gave the source of her plagiarized definitions. It would also be helpful if she proofread what she copied and pasted so "oceansa" would be corrected -- it should be "oceans a ... "

The main difference between a sea and an ocean lies in their size, depth, and their relationship to landmasses. Here's how to understand the difference:

1. Size: Oceans are significantly larger than seas. Oceans are massive bodies of saltwater that cover around 70% of the Earth's surface, encompassing millions of square miles. Seas, on the other hand, are smaller and are typically found where the ocean meets the land.

2. Depth: Oceans are generally deeper than seas. Oceans, like the Pacific and Atlantic, can have depths surpassing thousands of feet, while seas tend to be shallower in comparison.

3. Connection to Land: Oceans are typically connected to multiple continents, whereas seas are often partially enclosed by land. Oceans are vast and interconnected, flowing freely between continents, while seas are often partially enclosed by landmasses, such as the Red Sea or the Mediterranean Sea.

4. Salinity: Both seas and oceans contain saltwater, but seas tend to be less saline compared to oceans. This is due to factors such as freshwater inflow from rivers and less extensive evaporation.


It's important to note that there is no strict scientific distinction between a sea and an ocean. The naming and categorization can vary depending on geographical context and regional conventions. Some larger bodies of water, like the Mediterranean Sea, are often referred to as seas despite being relatively large.
