PPT-Convection A Process of the Water Cycle

What is CONVECTION Convection is the process by which heat is transferred A warmed liquid or gas comes into contact with an unheated space Heat transfer from liquid to surrounding air We see examples of this every day. By Ross . Nuechterlein. Convection. Convection.  is the movement of molecules within fluids and is one of the major modes of heat and mass transfer in liquids and gas.. Buoyancy . Buoyancy.  is an upward acting force exerted by a fluid , that opposes an object's weight.. Brian . Mapes. RSMAS. , University of Miami. Harvard, Oct 17 2009. (personal) historical moment.
