Why are there sudden changes of temperature when you’re walking near a running body of water?
In: Earth Science
Evaporation takes away heat energy from the surroundings. So the water is sucking up energy, causing the surrounding temperature to fall.
In a still body of water, the warm water rises to the top. This layer of warm water doesn’t absorb that much heat before it evaporates. In a moving body of water, this layer gets mixed up, bringing cooler water up to the top, which can absorb more heat to evaporate. This is why the area near a moving body of water feels cooler than a still body of water.
