  2. Terminal moraine - Wikipedia

    en.wikipedia.org/wiki/Terminal_moraine

    There is a glacier-fed lake in addition to the formation of a small channel heading in the southeast direction. During glacial retreat, meltwater flows in the opposite direction of the retreat, causing braided streams and channels to form. A terminal moraine creates a barrier helping to trap water in a newly-formed glacial lake.

  3. Moraine - Wikipedia

    en.wikipedia.org/wiki/Moraine

    Lateral moraines are those formed at the side of the ice flow, and terminal moraines are those formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet).

  4. Fluvioglacial landform - Wikipedia

    en.wikipedia.org/wiki/Fluvioglacial_landform

    Lateral Moraine: moraine in upper Engadin left by retreating glacier Lateral moraines are ridges of sediment deposited alongside the glacier running parallel to the long axis of the glacier. These sediments are typically deposited on top of the ice ( supraglacial till) at the margin of the glacier and as such do not experience the same amount ...

  5. Glacial landform - Wikipedia

    en.wikipedia.org/wiki/Glacial_landform

    Moraine: Built up mound of glacial till along a spot on the glacier. Feature can be terminal (at the end of a glacier, showing how far the glacier extended), lateral (along the sides of a glacier), or medial (formed by the merger of lateral moraines from contributory glaciers). Types: Pulju, Rogen, Sevetti, terminal, Veiki

  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]

  7. Glacier - Wikipedia

    en.wikipedia.org/wiki/Glacier

    Glaciers erode terrain through two principal processes: plucking and abrasion. [57] As glaciers flow over bedrock, they soften and lift blocks of rock into the ice. This process, called plucking, is caused by subglacial water that penetrates fractures in the bedrock and subsequently freezes and expands. [58]

  8. Glacial series - Wikipedia

    en.wikipedia.org/wiki/Glacial_series

    In the Alps the remaining flank moraines were usually formed during the Little Ice Age in medieval times. They lie several metres higher than the present glacier surface and extend far beyond the present glacier snouts. Medial moraines are formed when the lateral moraines of two glaciers are combined when they flow together.

  9. Till - Wikipedia

    en.wikipedia.org/wiki/Till

    Till is deposited as the terminal moraine, along the lateral and medial moraines and in the ground moraine of a glacier, and moraine is often conflated with till in older writings. [16] Till may also be deposited as drumlins and flutes, though some drumlins consist of a core of stratified sediments with only a cover of till. [17]
