Timeline of glaciation. There have been five or six major ice ages in the history of Earth over the past 3 billion years. The Late Cenozoic Ice Age began 34 million years ago, its latest phase being the Quaternary glaciation, in progress since 2.58 million years ago. Within ice ages, there exist periods of more severe glacial conditions and ...
The Pleistocene (/ ˈplaɪstəˌsiːn, - stoʊ -/ PLY-stə-seen, -stoh-; [5][6] often referred to colloquially as the Ice Age) is the geological epoch that lasted from c. 2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.
There have been three major glaciations during the Phanerozoic (the past 540 million years), including the Andean/Saharan (recorded in rocks of South America and Africa), the Karoo (named for rocks in southern Africa), and the Cenozoic glaciations.
The timeline of glaciation covers ice ages specifically, which tend to have their own names for phases, often with different names used for different parts of the world. The names for earlier periods and events come from geology and paleontology.
Pleistocene Epoch, earlier and major of the two epochs of the Quaternary Period of Earth’s history, an epoch during which a succession of glacial and interglacial climatic cycles occurred. It ended 11,700 years ago. It was preceded by the Pliocene Epoch and followed by the Holocene Epoch.
11 Μαρ 2015 · There have been at least five significant ice ages in Earth’s history, with approximately a dozen epochs of glacial expansion occurring in the past 1 million years.
24 Νοε 2023 · Describe the nature of temperature changes that led up to each of these glacial periods, and how the temperature changed in the immediate post-glacial period. The current interglacial (Holocene) is marked with an H. Identify the previous five interglacial periods. Exercise answers are provided Appendix 2.
