A wave carries energy on the ocean's surface. Waves can be big, like tsunamis, or small. The current is the constant movement of the water in the ocean, and there are different kinds of currents, defined by their characteristics and locations.

What is difference between wave and current?

Waves are created by the wind and then radiate in all directions away from the disturbance. Currents represent the movement of water particles which is controlled by winds and density differences.

What are currents and waves caused by?

Waves transmit energy, not water, and are commonly caused by the wind as it blows across the ocean, lakes, and rivers. Waves caused by the gravitational pull of the moon and the sun are called tides. The ebb and flow of waves and tides are the life force of our world ocean.
