Water currents
Water hardly ever stands still. It flows from high to low. These currents are part of the recycling of water. Ocean currents are caused by the earth's rotation, the tidal waves in the oceans and the wind. The waves at sea are caused by these currents together with the wind. A tsunami is not a current but a gigantic wave caused by underwater earthquakes.
