Cold and salty water sinks. Warm and less salty water rises. This creates a current.

thermo= heat. haline= salt

What causes surface currents?

• Changes in density rather than wind

• Wind

• It carries or moves things around the world

• When wind blows across the ocean’s surface and pushes water away from an area. Deeper colder water then rises to replace it
