Answer: Option (A)
Explanation:
The interior of the earth radiates a huge amount of energy due to the presence of molten heavy materials namely iron and nickel. This heat energy drives the plates to move over the mantle.
This radiated energy plays a significant role in increasing the temperature at the lower atmosphere. At the lower atmosphere majority of the air is concentrated due to its high density and are attached to the ground because of gravity.
This radiated heat energy then heats up this air particles that leads to an increasing air pressure and temperature.
