catastrophism

The geologist explained the principle of catastrophism to the students.

Definition

1. Noun:
   • Geological theory: "catastrophism" is the theory that the Earth's geological features have been shaped primarily by sudden, short-lived, violent events, such as floods, volcanic eruptions, or asteroid impacts, rather than by slow, gradual processes.
   • Historical context: In the history of science, "catastrophism" was a dominant view before the 19th century, often linked to biblical accounts of the Great Flood, and it contrasts with uniformitarianism.

Usage Examples

• Noun:
  • The scientist argued that catastrophism could explain the rapid formation of the Grand Canyon. (The theory that sudden violent events shaped the landscape.)
  • Many early geologists adhered to catastrophism, believing that Earth's history was marked by global disasters. (A historical geological perspective.)

Advanced Usage

• "Catastrophism in modern science": A revived form of catastrophism, sometimes called "neo-catastrophism," acknowledges that rare, catastrophic events (like asteroid impacts) have played a significant role in Earth's history, especially in mass extinctions.
  • The discovery of the Chicxulub crater revived interest in catastrophism as an explanation for the dinosaurs' extinction. (A modern application of the theory.)
