=Convection= Definition: the transfer of heat energy through the movement of currents in gas or liquid

Convection currents along a coastline

Facts: 1. In forced convection, heat is passively carried by fluid motion which would occur without the heating process 2. In natural convection, the heat is what causes the fluid motion, which causes the heat to be moved around in a current 3. Convection also occurs in the gasses of the Sun 4. In convection, warm currents rise, while cool currents fall 5. Hail forms as a result of convection currents carrying the ball of ice up where it keeps refreezing and adding water until it becomes too heavy and falls to earth.

Applications: 1. Convection is used in ovens to heat food evenly 2. It is what causes flares on the Sun 3. It keeps the weather moderate along the coastline, due to cool air from the ocean
