  2. Glacial motion - Wikipedia

    en.wikipedia.org/wiki/Glacial_motion

    Glacial lakes have been rapidly forming on the surface of the debris-covered glaciers in this region during the last few decades. USGS researchers have found a strong correlation between increasing temperatures and glacial retreat in this region. Glacial motion is the motion of glaciers, which can be likened to rivers of ice. It has played an ...

  3. Glacial period - Wikipedia

    en.wikipedia.org/wiki/Glacial_period

    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]

  4. Subglacial stream - Wikipedia

    en.wikipedia.org/wiki/Subglacial_stream

    Glacial motion can also cause changes in subglacial stream systems, and there are feedbacks present between the two. [7] As subglacial water pressure increases, the speed of glacial sliding increases. The glacier encounters bumps in the bedrock as it slides: as a result, cavities are created between the ice and the bed. [7]

  5. Timeline of glaciation - Wikipedia

    en.wikipedia.org/wiki/Timeline_of_glaciation

    Within ice ages, there exist periods of more severe glacial conditions and more temperate conditions, referred to as glacial periods and interglacial periods, respectively. The Earth is currently in such an interglacial period of the Quaternary glaciation, with the Last Glacial Period of the Quaternary having ended approximately 11,700 years ago.

  6. Glacial stream - Wikipedia

    en.wikipedia.org/wiki/Glacial_stream

    A glacier stream is a channelized area that is formed by a glacier in which liquid water accumulates and flows. [1] Glacial streams are also commonly referred to as "glacier stream" or/and "glacial meltwater stream". The movement of the water is influenced and directed by gravity and the melting of ice. [1]

    Last Glacial Period, not to be confused with the Last Glacial Maximum or Late Glacial Maximum below. (The following events also fall into this period.) 48,000–28,000: Mousterian Pluvial wet in North Africa 26,500–19,000: Last Glacial Maximum, what is often meant in popular usage by "Last Ice Age" 16,000–13,000

  8. Glaciology - Wikipedia

    en.wikipedia.org/wiki/Glaciology

    Movement (of ice) in a constant direction. Fracture Brittle failure (breaking of ice) under the stress raised when movement is too rapid to be accommodated by creep. It happens, for example, as the central part of a glacier moves faster than the edges. Glacial landform Collective name for the morphologic structures in/on/under/around a glacier ...

    They also showed Mars' precession had a period of about 51 kyr, obliquity had a period of about 120 kyr, and eccentricity had a period ranging between 95 and 99 kyr. In 2003, Head, Mustard, Kreslavsky, Milliken, and Marchant proposed Mars was in an interglacial period for the past 400 kyr, and in a glacial period between 400 and 2100 kyr, due ...
