Conduction
The transfer of heat energy by molecular and electron collisions within a substance (especially a solid)
Convection
The transfer of heat energy in a gas or liquid by means of currents in the heated fluid. The fluid moves, carrying energy with it.
Radiation
The transfer of energy by means of electromagnetic waves.
Terrestrial Radiation
The radiation emitted by Earth to outer space.
Newton's Law of Cooling
The rate of loss of heat from a warm object is proportional to the temperature difference between the object and its surroundings.
Greenhouse Effect
Warming of the lower atmosphere by short-wavelength radiation from the Sun that penetrates the atmosphere, is absorbed by Earth, and is re-radiating at longer wavelengths that cannot easily escape Earth's atmosphere.
Solar Constant
W1400 J/m^2 received from the sun each second at the top of Earth's atmosphere on an area perpendicular to the Sun's rays; expressed in terms of power, 1.4 kW/m^2
Solar Power
Energy per unit time received from the Sun.
