Quaternary (Atmospheric Chemistry)

The period of Earth's history from about 2 million years ago to the present; also, the rocks and deposits of that age.

Quaternary (Earthquake)

The geologic time period comprising about the last 1.65 million years.

Quaternary (Geologic)

The most recent Period of the Cenozoic Era. Encompasses the time interval of 1.6 million years ago through today.

Quaternary (Natural Hazards)

The geologic time period comprising about the last 1.65 million years.

Quaternary (Paleontology)

The second period of the Cenozoic era, spanning the time between 1.8 million years ago and the present. It contains two epochs: the Pleistocene and the Holocene. It is named after the Latin word "quatern" (four at a time).

Quaternary (Physical Geography)

Geologic period that occurred roughly 1.6 million years ago to today. During much of this period continental glaciers in the Northern Hemisphere covered large regions of land surface in the high and mid-latitudes. Homo sapiens appear about 200,000 years BP (before present) and become the first species to alter the Earth's environment on a large-scale.

Quaternary (Speleological)

The youngest geological period, extending from the end of the Tertiary 1.6 million years ago to the present. Divided into Pleistocene, and Holocene which is the last 10,000 years. A time of great ice ages with widely fluctuating climates and sea levels.
Geology.

Quaternary (Volcano)

Period of geologic time from about 2 million years ago until the present. It contains the Pleistocene (2 million - 8,000) and Holocene (8,000 - present) epochs.
