If the Sun's energy heats a rock, how will the heat be transferred to a person's hand holding the rock?

• by convection, because heat from the rock flows through empty space into the person's hand

• by radiation, because the atoms in the rock excite the atoms in the person's hand

• by convection, because thermal energy circulates atoms in the person's hand

• by conduction, because heat travels from the atoms in the rock to the atoms in the person's hand
