The Pleistocene (/ ˈ p l aɪ s t ə ˌ s iː n,-s t oʊ-/ PLY-stə-seen, -stoh-; [4] [5] 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.
The Quaternary glaciation, also known as the Pleistocene glaciation, is an alternating series of glacial and interglacial periods during the Quaternary period that began 2.58 Ma (million years ago) and is ongoing.
The Early Pleistocene is an unofficial sub-epoch in the international geologic timescale in chronostratigraphy, representing the earliest division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently estimated to span the time between 2.580 ± 0.005 Ma (million years ago) and 0.773 ± 0.005 Ma.
The Quaternary Period is a geologic time period that can be separated into two epochs, the Pleistocene ("most recent") Epoch, generally defined as beginning about 2.58 million years ago, and the Holocene ("wholly modern") Epoch, which began about 11,700 years ago. [5] [6] The study of Quaternary science began in the late eighteenth century in ...
The Late Pleistocene is an unofficial age in the international geologic timescale in chronostratigraphy, also known as the Upper Pleistocene from a stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c ...
But, if it feels like one just appeared out of nowhere, you might be wondering what causes them in the first place. The reality is that we don’t always know why skin tags form, ...
"An asteroid this size impacts Earth on average every few thousand years and could cause severe damage to a local region," the European Space Agency said. An asteroid could hit Earth in 2032, NASA ...
The Pleistocene extends from to 11,700 years before present. [10] The modern continents were essentially at their present positions during the Pleistocene , the plates upon which they sit probably having moved no more than 100 kilometres (62 mi) relative to each other since the beginning of the period.
