Respuesta :
Hot air expands and rises, becoming cooler and denser, then falling again in a continuous process
The convection current in the atmosphere is best explained as the process by which hot air expands and rises, becoming cooler and denser, then falling again in a continuous process.
Heat transfer by convection involves the transfer of heat by the actual movement of the heated molecules from the hot parts to the cooler parts of a fluid.
The continuous movement of hot air or liquid from bottom to the top and cold liquid or air from the top to the bottom is known as convection current.
Thus, we can conclude that convection current in the atmosphere is best explained as the process by which hot air expands and rises, becoming cooler and denser, then falling again in a continuous process.
