Depositional

• drumlin

  hit obstacle cant be eroded, deposition under glacier builds up behind obstacle

  moves over mound, drags excess deposition over other side

  cause tear drop shape
• erratics

  large boulder, diff rock type to surrounding rock - broken off by weathering + erosion, transported + deposited by glacier when lost energy
• What are lateral moraines?

  Moraines deposited on the sides of a glacier that leave a ridge when the ice melts.
• What are medial moraines?

  Moraines formed when two lateral moraines meet in the middle of a glacier.
• What are ground moraines?

  Moraines that are found underneath a glacier and consist of only sorted material.
• What are recessional moraines?

  Moraines formed at the end of a glacier.
• What are terminal moraines?

  Moraines found at the snout of a glacier on the valley floor.
• till plains

  unsorted material formed through erosion and weathering

  
  

  ice sheet detaches from glacier + melts, till on top/within glacier deposited on valley floor
