Catastrophism, a theory of the Earth’s development posited by the naturalist Georges Cuvier, proposed that Earth’s history was the result of frequent geological catastrophes.

Why does the principle of lateral continuity work?

The principle of lateral continuity states that layers of sediment initially extend laterally in all directions; in other words, they are laterally continuous. As a result, rocks that are otherwise similar, but are now separated by a valley or other erosional feature, can be assumed to be originally continuous.

What is gradualism in geology?

Gradualism in biology and geology refers most broadly to a theory that changes of organic life and of the Earth itself occur through gradual increments, and often that transitions between different states are more or less continual and slow rather than periodic and rapid.

What are Actualistic studies?

Actualistic studies are used in which behavior can be tied to diagnostic material remains, regardless of the cultural setting. These studies range from observing modern trash-disposal patterns to examining how one group of hunters differs from another in consuming its prey.

What is Actualistic research?

Actualistic Study en 8751. added by archaeologs Detailed observation of the actual use of archaeological artifacts, ecofacts, and features, used to produce general analogies for archaeological interpretation.

What is Ethnoarchaeology How does it help the study of history?

Ethnoarchaeology is the ethnographic study of peoples for archaeological reasons, usually through the study of the material remains of a society (see David & Kramer 2001). Ethnoarchaeology aids archaeologists in reconstructing ancient lifeways by studying the material and non-material traditions of modern societies.
