Quaternary Geology

Quaternary geology refers to the study of Earth's geological and environmental changes during the Quaternary period, which spans the last 2.6 million years, characterized by significant climatic fluctuations and the development of modern ecosystems. Climate change in this context encompasses the natural and anthropogenic alterations in climate patterns that have occurred during this period, influencing biodiversity, glacial dynamics, and sea-level rise.

Key Terms

Quaternary Period
The most recent geological time period, spanning the last 2.6 million years.

Example: The Quaternary period includes the last Ice Age.

Glacial Period
A time during which glaciers cover significant portions of the Earth.

Example: The last glacial period ended about 11,700 years ago.

Interglacial Period
A warmer period between glacial periods.

Example: The current Holocene epoch is an interglacial period.

Paleoclimate
The climate of the Earth in the geological past.

Example: Paleoclimate studies help us understand ancient weather patterns.

Ice Core

Example: Ice cores provide valuable climate data over thousands of years.

Sediment Analysis
The study of sediment layers to understand past environments.

Example: Sediment analysis reveals information about ancient ecosystems.
