1. Figure 8 is an aerial photograph of a periglacial landscape in northern Canada.

Figure 8

Note: There are thousands of small, medium and large scale lakes in this region. This image was taken in early summer and much of the ice has yet to thaw. Local relief and other aspects of geomorphology determine the rate at which ice melts.

Using Figure 8 and your own knowledge, assess the relative importance of factors leading to the development of this landscape.
