Key Concepts

Gradualism

Gradualism is the concept that geological and biological changes occur through slow, continuous, and cumulative processes over extended periods. In geology, this idea suggests that the earth's features—such as mountains, valleys, and other landforms—are primarily the result of long-term, steady processes like erosion, weathering, and sedimentation, rather than sudden, dramatic events. This approach aligns closely with the principle of uniformitarianism, which posits that the same natural processes observable today have operated in the past.

Catastrophism

Catastrophism is the idea that the earth's landscape and geological record have been significantly shaped by sudden, short-lived, and violent events, such as massive volcanic eruptions, meteor impacts, or floods. This theory emphasizes that catastrophic events, although rare, can produce rapid and dramatic changes that leave distinct marks on the geological record. It contrasts with gradualism by focusing on the role of abrupt, large-scale events in shaping the earth.
