Detailed explanation-1: -The theory of catastrophism is the idea that Earth’s surface and landscape can largely be explained by sudden, short-lived, and violent events such as cataclysmic earthquakes, floods, and volcanic eruptions.

Detailed explanation-2: -Uniformitarianism suggests that the geological features of Earth were created in slow incremental changes such as erosion. In contrast, catastrophism states that the Earth has largely been sculpted by sudden, short-lived, violent events. So, this is the key difference between uniformitarianism and catastrophism.

Detailed explanation-3: -Today, we hold uniformitarianism to be true and know that great disasters such as earthquakes, asteroids, volcanoes, and floods are also part of the regular cycle of the earth.
