Landforms of glacial deposition L.O. To be able to explain the formation of drumlins.  To understand what boulder clay and erratics are and understand how they are formed.
What is this? How would you describe it ? How is it formed ? What has this got to do with glaciation?
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?
Erratics Erratics are large b___________ carried by the ice and d__________ in an area of d___________ rock.
Drumlins Drumlins are smooth elongated m----- of material formed p-r--l-l to the d-r-c-i-n of ice movement.  They are typically about 30 – 40m high and 300 – 400m long They often consist of stones and c--- and are thought to result from the --ad carried by a ------- becoming too heavy and being deposited.
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 _________. blunt tapered Boulder clay downstream upstream
upstream downstream Blunt end Tapered end
