Does Rain Follow the Plow?
What makes it rain? Many people joke it only takes washing the car or forgetting an umbrella to make rain fall, though in reality, those things are two of many rain-making myths that have been perpetuated throughout the years.
In the 19th century, the "rain follows the plow" myth was used to justify settlement of the Great Plains. The cultivation of semi-arid to arid land was said to increase rainfall by moistening the soil and humidifying the atmosphere. Subsequent research debunked the myth, though large discrepancies still existed between model representations and actual observations.
