A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. [1]
Glacial history of Minnesota; Glacial period – Interval of time within an ice age that is marked by colder temperatures and glacier advances; Ice age – Period of long-term reduction in temperature of Earth's surface and atmosphere; Last Glacial Period – Period of major glaciations of the Northern Hemisphere (115,000–12,000 years ago)
Last Glacial Period, the most recent glacial period (115,000 to 11,700 years ago) Penultimate Glacial Period, the glacial period that occurred before the Last Glacial Period; Late Cenozoic Ice Age, the geologic period of the last 33.9 million years; Little Ice Age, a period of relative cold in certain regions from roughly 1450–1480
A chronology of climatic events of importance for the Last Glacial Period, about the last 120,000 years The Last Glacial Period caused a much lower global sea level.. The Last Glacial Period (LGP), also known as the Last glacial cycle, occurred from the end of the Last Interglacial to the beginning of the Holocene, c. 115,000 – c. 11,700 years ago, and thus corresponds to most of the ...
This climatic history is implied by the types of fossil plants and animals and by the characteristics of sediments preserved in the stratigraphic record. [46] There are, however, widespread glacial deposits, recording several major periods of ancient glaciation in various parts of the geologic record.
Violet: The extent of the Alpine ice sheet in the Würm glaciation. Blue: The extent in earlier ice ages. The Würm glaciation or Würm stage (German: Würm-Kaltzeit or Würm-Glazial, colloquially often also Würmeiszeit or Würmzeit; cf. ice age), usually referred to in the literature as the Würm [1] (often spelled "Wurm"), was the last glacial period in the Alpine region.
It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. [4] The Holocene and the preceding Pleistocene [5] together form the Quaternary period. The Holocene is an interglacial period within the ongoing glacial cycles of the Quaternary, and is equivalent to Marine Isotope Stage 1.
In contrast, the rest of the glacial period was so cold that the dominant plant in the area was a small, cold-adapted flower called Dryas octopetala. [3] Thus, the cold period which preceded this interstadial is known as the Oldest Dryas, and the two subsequent cold periods as the Older and Younger Dryas. [3]
