Question : Even after sunset, the air near the Earth's surface continue to receive heat due to
Option 1: Isolation
Option 2: Terrestrial Rediation
Option 3: Conduction
Option 4: Convection
Correct Answer: Terrestrial Rediation
Solution : The correct option is Terrestrial Rediation.
The Earth's surface begins to lose heat after sunset, a process known as terrestrial radiation or terrestrial cooling. This process includes the emission of infrared radiation (thermal energy) into the atmosphere from the Earth's surface. The ground, buildings, and other objects on the Earth's surface absorb heat from the sun during the day and release this stored heat energy as infrared radiation at night. Terrestrial radiation is an important component of the Earth's energy balance, and it is one of the reasons why temperatures frequently drop after sunset.
