MODES OF HEAT TRANSFER
1. Conduction: This type of heat transfer happens when there is direct contact between the two objects.
2. Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas).
3. Radiation: This type of heat transfer happens when there is direct transfer of energy through space.
Thus convection can not take place between earth and sun as there is no liquid or gas present for movement of heat. The heat is transferred from sun to earth by radiation as it occurs through space.
