In the summer of 2016, people sweltering in the midwestern United States didn't say, "It's not the heat, it's the humidity." Instead, they said "It's the cornsweat." Many blamed surrounding acres of cornfields for increasing the perceived temperature, already at record levels. Considering what you know about the water cycle, what information might address this idea?
A. Since most atmospheric water vapor over land comes from evaporation from lakes and rivers, corn has nothing to do with it. B. Since local temperatures are based on climate, and plants capture carbon dioxide, the fields of corn plants should actually decrease local temperatures. C. Most atmospheric water vapor in the Midwest has been blown there from water that evaporated from the ocean. Corn has nothing to do with it. D. Since 90% of the water in the atmosphere over land arrived there by evapotranspiration, it is reasonable to conclude that increased acreage of corn cultivation could increase local humidity.
