What is Ocean currents?
Ocean currents are large, continuous flows of seawater driven by wind, temperature, salt, and Earth's rotation. They move heat around the globe, shaping climates — like the Gulf Stream warming Western Europe — and carrying nutrients that support marine life.

Frequently asked questions
- What are ocean currents?
- Large, continuous movements of seawater driven by wind, temperature, salinity, and Earth's rotation.
- Why do ocean currents matter?
- They move heat around the planet, shaping climates and supporting marine life with nutrients.
- What is the Gulf Stream?
- A powerful warm current that carries heat from the tropics, helping keep Western Europe mild.
