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?
What will be an ideal response?


Answer: The Earth is shaped by catastrophic events such as earthquakes and floods, which cause major changes in a short period of time. However, the Earth is also shaped by small, gradual changes such as stream deposition and weathering, which may only show measurable change after several decades or centuries. In reality, both views are correct.
