What does catastrophism refer to in geology?

• A. Belief that Earth was shaped by gradual processes.
• B. Theory of plate tectonics.
• C. Theory of evolution.
• D. Belief that Earth was shaped by sudden, short-term catastrophic events.

Answer: (D)

Catastrophism focuses on the idea that Earth’s landscapes were shaped mainly by brief, dramatic events rather than slow, steady changes. It suggests that sudden floods, volcanic eruptions, meteor impacts, and other disasters produced major geographic features in a relatively short time. This view contrasts with the notion that the planet is formed gradually through small, continuous processes. Historically, catastrophism stood in opposition to uniformitarian ideas, which stress continual, day-to-day processes like weathering and erosion shaping the Earth over long spans. In modern geology, both rapid events and long-term processes are recognized as contributing to the planet’s features. The belief described here is the one that emphasizes sudden, short-term catastrophes.
