Detailed explanation-1: -Which tranfer of energy occurs mainly through the process of convection? (3) Convection involves the transfer of heat due to density differences within a fluid. Heated air in the lower atmosphere transferred upward by density differences.
Detailed explanation-2: -Energy is transferred between the Earth’s surface and the atmosphere in a variety of ways, including radiation, conduction, and convection. Conduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection.
Detailed explanation-3: -Convection is the most important way that heat travels in the atmosphere. Convection currents are the main way that heat moves through the atmosphere.
Detailed explanation-4: -In the atmosphere, conduction is more effective at lower altitudes where air density is higher; transfers heat upward to where the molecules are spread further apart or transfers heat laterally from a warmer to a cooler spot, where the molecules are moving less vigorously.
Detailed explanation-5: -The transfer of thermal energy by the movement of matter from one place to another is called convection. Convection occurs in the atmosphere when conduction heats air close to Earth’s surface.
