Solution

The correct option is A False
Heat from the Earth's core and radiation from the sun is transferred to the surface of earth by the process of conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy , which then heats up the rest of the air through convection. Heat transfer also takes place through radiation but not as much as conduction and convection.
