Explanation:
Catastrophism is a geological concept or ideology that was formerly in place. It suggests that the earth crust has evolved through only drastic and violent geological events.
Uniformitarianism suggests that the earth carefully evolved over a period of time and that the processes that are occurring today have occurred in times past.
- Catastrophism presents a drastic and rapid evolution of the crust.
- Uniformitarianism takes a gradual approach to events and suggests that we can use the present to unravel the past.
