Lateral moraine – material derived from freeze-thaw weathering of valley sides and which is carried at the sides of a glacier.
Medial moraine – found in the centre of a glacier and results from two lateral moraines joining together.
Ground moraine is material dragged underneath a glacier.
Terminal moraine – marks the maximum advance of a glacier. It is the rock material deposited at the snout of a glacier.
Recessional moraines – these form behind and parallel to the terminal moraine. They mark stages in the retreat of a glacier when it remained stationary for long enough for a ridge of material to develop.
What is this? How did it get to be like this? How would you describe it ? How is it formed ? Why is the bed rock a different colour than the boulder? What has this got to do with glaciation? What processes have occurred?
Most deposition occurs around the _______end which forms the drumlin’s ______ end. The rest of the _______ that is deposited is then moulded into shape by the moving ice to form the _______ end _________.
