What role does a water source play in morning mist near a river or lake?

Answer and explanation

Correct answer: It supplies moisture to the air

Correct answer: A, it supplies moisture to the air. A river or lake has an exposed water surface. Some water evaporates from this surface and adds water vapour to the nearby air. During the night and early morning, the air and the ground may cool. If moist air cools sufficiently, it can reach saturation, and some water vapour condenses into very small liquid droplets suspended near the ground. This produces mist or fog-like conditions. A is correct because the water body is a local source of moisture. B is wrong because evaporation generally adds moisture rather than removing it. C is wrong because a water source does not remove sunlight; morning light may still be present. D is wrong because air cannot turn into rock through mist formation. Memory cue: water source supplies moisture, while cooling changes that moisture into droplets.
