The Nature of Weather: Conduction, Convection, and Radiation

The video tutorial explains three methods of heat transfer: conduction, convection, and radiation. Conduction is demonstrated with a spoon in boiling water, showing how heat travels through direct contact. Convection is illustrated with examples of air and fire, highlighting how heat moves through fluids. Radiation is discussed in the context of the sun's energy reaching Earth, emphasizing its importance in warming the planet.
