The catastrophic school of thought in geomorphology is a theory that suggests that major geological features and landforms on Earth were primarily formed by sudden and catastrophic events, rather than gradual and slow processes. This theory contrasts with the uniformitarian school of thought, which posits that geological features are the result of slow and continuous processes over long periods of time.
Proponents of the catastrophic school of thought argue that events such as massive floods, volcanic eruptions, earthquakes, and meteorite impacts have played a significant role in shaping the Earth's surface. They point to evidence such as large-scale sediment deposits, massive erosion, and sudden changes in topography as support for their theory.
One of the most famous proponents of the catastrophic school of thought was the geologist and paleontologist Georges Cuvier, who proposed the theory of catastrophism in the early 19th century. Cuvier believed that a series of catastrophic events, such as floods and earthquakes, had caused major extinctions and changes in the Earth's surface throughout history.
While the catastrophic school of thought has fallen out of favor in recent decades, some researchers still study and consider the role of catastrophic events in shaping the Earth's surface. They argue that while gradual processes such as erosion and weathering are important, catastrophic events can also have a significant impact on the Earth's geomorphology.

Catastrophic School of Thought in Geomorphology
The catastrophic school of thought was a viewpoint in geomorphology that emphasized the role of sudden, catastrophic events in shaping landscapes. It arose in the late 18th and early 19th centuries, primarily due to the influence of Scottish geologist James Hutton.
Key Principles:
- Sudden, infrequent events: Landscapes are shaped by infrequent, catastrophic events such as earthquakes, floods, and volcanic eruptions.
- Rapid, violent processes: These events cause rapid and violent changes in the landscape, often leaving behind dramatic landforms.
- Biblical flood: Many catastrophists believed that the Great Flood described in the Bible had a profound impact on Earth's surface.
Examples of Landforms:
Catastrophists identified specific landforms that they attributed to catastrophic events:
- Hanging valleys: Tributary valleys that end abruptly at higher elevations than the main valley.
- Kettle lakes: Circular depressions left by melting glaciers.
- Giant glacial erratics: Boulders of unusual size and composition transported by glaciers.
Criticism and Decline:
The catastrophic school of thought was challenged by later geologists who advocated for gradualism, the idea that landscapes are shaped by slow, continuous processes over long periods.
Criticisms of catastrophism included:
- Lack of evidence: Many catastrophic landforms could be explained by gradual processes.
- Geological timescale: The geological record does not support the frequency of catastrophic events proposed by catastrophists.
- Erosion and weathering: Gradual erosion and weathering can produce landforms that resemble those attributed to catastrophic events.
By the mid-19th century, gradualism became the dominant paradigm in geomorphology, although the influence of catastrophism can still be seen in some modern studies of rapid geomorphic processes.
