GEOLOGY

Detailed explanation-1: -Catastrophism states that natural history has been punctuated by catastrophic events that altered that way life developed and rocks were deposited.

Detailed explanation-2: -Catastrophism suggested the features seen on the surface of Earth, such as mountains, were formed by large, abrupt changes-or catastrophes. When discussing past climates, opponents to uniformitarianism may speak of no-analog changes.

Detailed explanation-3: -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-4: -Catastrophism holds that every so often a major destructive event or catastrophe will dramatically reshape the earth’s surface. Gradualism, on the other hand, argues that changes to the earth’s surface occur very slowly, over a long period of time.
