TEST ON PLANT AGRICULTURE

Many early farmers of the Western U.S. plains believed a theory called “Rain Follows the Plow.” What was the problem with this theory?

• Farming actually makes it rain less, not more.

• The climate at the time farming took place was not any different than normal.

• The usually high precipitation during this period of early farming and settling was a coincidence.

• This theory is actually true. Farming and settling an area makes it rain more frequently.
