Correct answer: radiation

Explanation: ✅ Correct Answer: C) radiation 📚 Explanation: Clear nights are significantly colder than cloudy nights because of the unchecked loss of heat from the Earth's surface through the process of terrestrial radiation. On a clear night, the heat radiated by the ground escapes easily into the upper atmosphere. When clouds are present, they act like an insulating blanket, trapping the radiated heat and reflecting it back toward the ground. This preserves a warmer surface temperature.
