7. Reflection The process whereby light bounces back from an object at the same angle at which it encounters a surface and with the same intensity.
8. Scattering The redirecting (in all directions) of light by small particles and gas molecules in the atmosphere; The result is more light rays with weaker intensity.
9. Greenhouse Effect The heating of Earth’s surface and atmosphere from solar radiation being absorbed and emitted by the atmosphere, mainly by water vapor and carbon dioxide.
10. Key Concept How are heat and temperature related? Heat is transferred from one object to another because of a difference in their temperatures.
11. Key Concept What are the three major mechanisms of heat transfer? Three mechanisms of energy transfer as heat are conduction, convection, and radiation.
