A map shows the major ocean currents flowing across the globe.

Definition

Noun: A continuous, directed movement of seawater generated by forces acting upon it, such as wind, temperature, salinity differences, and the Earth's rotation. It is a large-scale, persistent flow within an ocean basin.

Usage

This term is used to describe the major, consistent flows of water in the world's oceans. It is a scientific and geographical term. - Ocean currents are crucial in regulating the Earth's climate. - The Gulf Stream is a powerful warm ocean current. - Scientists study how ocean currents distribute heat around the globe.
