WebThe atmosphere directly absorbs about 23% of incoming sunlight, and the remaining energy is transferred from the Earth’s surface by evaporation (25%), convection (5%), and thermal infrared radiation (a net of 5-6%). … WebRadiation may be thought of as energy in motion either at speeds equal to the speed of light in free space—approximately 3 × 10 10 centimetres (186,000 miles) per second—or at speeds less than that of light but …
WebHeat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact. Convection is the movement of heat by a fluid such as water or air. Radiation is the transfer of heat by electromagnetic waves. WebHeat transfer through radiation does not require a medium through which heat is transferred. Different electromagnetic waves have different wavelengths and travel in a vacuum with the same speed as the speed of light, 3 x 10 8 m s -1 .
