Sea vs. River: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 10, 2023
The sea is a large body of saltwater, often connected to an ocean, while a river is a flowing body of freshwater, usually moving towards a sea, lake, or another river.

Key Differences

The sea is a vast body of saltwater, covering about 71% of Earth's surface and serving as a major component of the planet's hydrosphere. On the other hand, rivers are natural flowing watercourses, typically freshwater, flowing towards an ocean, sea, lake, or another river.
