The Earth as a whole neither accumulates heat nor loses it due to sol...
Explanation:
The correct answer is option B: The Earth, in turn, radiates back solar insolation received from the Sun.
Reasoning:
The Earth receives solar insolation from the Sun in the form of electromagnetic radiation. This energy is absorbed by the Earth's atmosphere, land, and oceans. However, the Earth as a whole neither accumulates heat nor loses it due to solar insolation because it radiates back an equal amount of energy into space. This process is known as radiative balance or radiative equilibrium.
Key Points:
- Solar insolation refers to the amount of solar radiation received per unit area on the Earth's surface.
- The Earth's atmosphere plays a crucial role in regulating the amount of solar energy that reaches the Earth's surface. It absorbs some of the incoming solar radiation and reflects or scatters the rest.
- The absorbed solar energy heats up the Earth's atmosphere, land, and oceans. However, this heat is not accumulated indefinitely.
- The Earth radiates energy back into space in the form of longwave infrared radiation. This radiation is emitted by the Earth's surface, the atmosphere, and clouds.
- The rate of energy radiated by the Earth is equal to the rate of energy received from the Sun. This balance between incoming and outgoing radiation is necessary to maintain a stable temperature on Earth.
- If the Earth were to accumulate more energy than it radiates, the temperature would continually increase, leading to a runaway greenhouse effect. Conversely, if the Earth were to lose more energy than it receives, the temperature would continually decrease, resulting in a global cooling effect.
- The maintenance of radiative balance is crucial for the Earth's climate system. It ensures that the Earth's temperature remains relatively stable over long periods.
Therefore, the correct answer is option B: The Earth, in turn, radiates back solar insolation received from the Sun.

The Earth receives almost all of its energy from the Sun. The Earth, in turn, radiates back to space the energy received from the Sun. As a result, the Earth neither warms up nor does it get cooled over a period of time.
