Question

Quizplus · Accepted Answer

Relative humidity is essentially a measure of how much moisture is in the air compared to how much moisture the air can actually hold at that temperature. It is expressed as a percentage, with 100% relative humidity meaning that the air is saturated and cannot hold any more moisture without causing precipitation. Option A refers to absolute humidity, which is not a measure of how saturated the air is. Option B is not a scientific definition of relative humidity, and option D is incorrect as relative humidity is a commonly used concept in weather forecasting and understanding weather patterns.
