Glacier - Deposition

Deposition

  • Lodgement till is identical to ground moraine. It is material that is smeared on to the valley floor when its weight becomes too great to be moved by the glacier.

  • Ablation till is a combination of englacial and supraglacial moraine. It is released as a stationary glacier begins to melt and material is dropped in situ.
  • Dumping is when a glacier moves material to its outermost or lowermost end and dumps it.
  • Deformation flow is the change of shape of the rock and land due to the glacier.
