- Depositional landforms
- LATERAL
- A mound of till on the side of a glacier (close to valley walls) - parallel to the direction of glacier flow
- Rock and debris falling from valley sides - frost shattering of rock wall
- Mer du Glace - France
- 1-50m high, as long as the glacier
- MEDIAL
- The junction between 2 glaciers - formed by the union of lateral moraines when 2 glaciers join together
- Material builds up where 2 glaciers meet to form a new glacier
- Material / debris of rocks and dirt is pushed into the one thin line
- PUSH
- Assorted debris that has been pushed up by a glacier as it moves forwards
- Till is deposited and pushed up from past glacial advances
- Several hundred m high, 100km long
- TERMINAL
- The line marking the furthest point of the glacier
- Ridges of till; material is thrust up through the glacier, as the glacier decelerates and melts
- The snout needs to remain stagnant to form till
- When the glacier stops and melts it deposits the materials across the floor
- Cromer Ridge, Norfolk
- RECESSIONAL
- A ridge of debris representing a stationary phase during a stagnant stage
- Found across the Valley floor - not along it
- Hight is dependant on how long the glacier is stagnant
- LATERAL
