Convection Currents Air and water

Explore convection currents! Understand how air and water move due to heat and pressure.

What isconvection? What causes convection currents in the atmosphere? What are air currents? Air currents are like rivers of wind caused by areas of high and low pressure.The air above the land is warmer and less dense, so it rises. The air over the water is cooler and heavier.
