Explain the relationship density has on wind currents and ocean currents.

The nature flows from high to low to form the equilibria in temperature, pressure or concentration.  Winds blow from high pressure area to low pressure zone. Colder winds occur from high pressure area while dry air are formed from low pressure area.  Ocean currents flow from warm breeze to cold breeze in day and reversed during night.

In both wind currents and ocean currents, movement occurs because warm air or water rises. Warm air and water is less dense than cold, and the difference between the two give rise to movements in the air or water. This difference in temperatures is what causes severe weather, such as tornadoes and severe thunderstorms.

Convection current is the main process through which heat is transferred in bulk from one location to another through the cyclic motion of a large volume of substance.
