In the sixteenth and seventeenth centuries, the doctrine of catastrophism was used to
describe how the Earth had been shaped quickly by fast, violent catastrophes and was
therefore very young. In the eighteenth century, James Hutton developed the principle
of uniformitarianism, which stated that the Earth was shaped by small, gradual changes
occurring over a long period of time, making the Earth much older. Which view (if
either) is correct, and why?
In the late spring and summer of 2012, the majority of the United States experienced a

Where did the water go?)
