Quaternary Geomorphology

 

 The Quaternary is the most recent geological period of time in Earth’s history, spanning the last two million years and extending up to the present day. The Quaternary period is subdivided into the Pleistocene  (“Ice Age”) and the Holocene (present warm interval) epochs, with the Pleistocene spanning most of the Quaternary and the Holocene covering the past 10 000 years. The Quaternary period is characterized by a series of large-scale environmental changes that have profoundly affected and shaped both landscapes and life on Earth. One of the most distinctive features of the Quaternary has been the periodic build-up of major continental ice sheets and mountain ice caps in many parts of the world during long lasting glacial stages, divided by warm episodes (interglacials) of shorter duration, when temperatures were similar to or higher than today. During long periods of these climatic cycles, perhaps 8/10th of the time, temperatures were cool or cold. The number of Quaternary interglacial-glacial cycles is probably in the order of 30-50. There have been shifts in the frequency of climate oscillations and amplitude of temperatures and glaciations through the Quaternary.
