Recap: Glacial Landforms

•Glaciers have played an important role in the shaping of landscapes in the middle and high latitudes and in alpine environments. Their ability to erode soil and rock, transport sediment, and deposit sediment is extraordinary. During the last glacial period more than 50 million square kilometers of land surface were geomorphically influenced by the presence of glaciers.

Identify Glacial Landforms on the Map

of Ben Nevis!Task 1

Just spend SOME time (maybe 15min) trying to identify landforms on the map. Just try to find a cirque, an arête, and the main glacier’s

trough.

Ben Nevis

Where on the map of Ben Nevis was this

picture taken?Task 2

Where on the map was this picture taken? Choose from the following possibilities:

• 15 71• 16 70• 17 73(coordinate grid systems refer to the left-bottom corner of the grid square)
