The greenhouse effect is a natural phenomenon that enables life to propagate in Earth. During the day, the Sun provides energy through sunlight. Note that the Sun's energy is obtained from the nuclear fusion of hydrogen to helium. So, sunlight contains radiation at very high temperatures. In order to regulate heat, the atmosphere allows only some of the heat to be absorbed into the surroundings, but blocking the rest and reflecting it back to space. During night time, without the Sun giving energy, greenhouse gases in the atmosphere has 'reserved' heat that is trapped in the atmosphere. So, the greenhouse gases (like water vapor and carbon dioxide) maintains the average temperature of the Earth's atmosphere at around 33°C.

Therefore, the answer is letter B.

Doubling the distance between you and a source of radiation decreases your exposure by:
Elan Coil [88]

Given what we know, we can confirm that doubling the distance between you and a source of radiation decreases your exposure by 75%.

<h3>How is distance related to radiation exposure?</h3>
  • As expected, increasing the distance from the source of the radiation will reduce its negative effects.
  • Counter-intuitively however, doubling the distance does not reduce by half, but rather reduces its effects by 3/4th.
  • This is due to the fact that the radiation effects from the source are inversely proportional to the square of the distance.
  • This causes the changes to be far greater than expected.

Therefore, given that the radiation is proportional to the square of the distance, instead of being of a more direct relation, we can confirm that when doubling the distance between yourself and the source of the radiation, you can reduce its effects by 3/4 or 75%.
