Quaternary geology is the branch of geology that study developments from 2.58 million years ago to the present. [ 1 ] [ 2 ] In particular, Quaternary geology study the process and deposits that developed during the Quaternary , a period characterized by glacial - interglacial cycles.
Quaternary science is the subfield of geology which studies the Quaternary Period commonly known as the ice age. The Quaternary Period is a time period that started around 2.58 million years ago and continues today. [1] [2] This period is divided into two epochs – the Pleistocene Epoch and the Holocene Epoch.
The Quaternary (/ k w ə ˈ t ɜːr n ə r i, ˈ k w ɒ t ər n ɛr i / kwə-TUR-nə-ree, KWOT-ər-nerr-ee) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS), as well as the current and most recent of the twelve periods of the Phanerozoic eon.

An example is the Pleistocene Epoch of the Quaternary Period. erosion The displacement of solids (sediment, soil, rock and other particles) usually by the agents of currents such as wind, water, or ice by downward or down-slope movement in response to gravity or by living organisms (in the case of bioerosion). erratic
Most alluvium is Quaternary in age and is often referred to as "cover" because these sediments obscure the underlying bedrock. Most sedimentary material that fills a basin ("basin fill") that is not lithified is typically lumped together as "alluvial". [9] Alluvium of Pliocene age occurs, for example, in parts of Idaho. [10]
With four elements, quaternary phases are more complex. The number of isomers of a ternary compound provide a distinction between inorganic and organic chemistry: "In inorganic chemistry one or, at most, only a few compounds composed of any two or three elements were known, whereas in organic chemistry the situation was very different." [2]
The participants self-reported their coffee-drinking habits, meaning results may be inaccurate, and the researchers didn't consider long-term consumption patterns. MORE: Good news for coffee ...
Quaternary is a term used in organic chemistry to classify various types of compounds (e. g. amines and ammonium salts). [ 1 ] Red highlighted central atoms in various groups of chemical compounds.
