Answer 1
There exist river valleys, both the main and a tributary valley. A glacier occupies former river valleys. Both the main and tributary valleys are occupied by the glacier. Since the rate of glacial erosion is determined by the size of the valley and amount of glacier, there will be more erosion on the main valley compared with the tributary valley. The main valley is therefore deepened and widened faster than the tributary valley. When the glacier melts, it exposes a deep, U-shaped glacial valley, with the smaller tributary valley suspended high up the valley side. The suspended tributary valley forms a hanging valley.
Answer 2
-Ice collects in the main valley and tributary valley.
-Glacial erosion through plucking/abrasion/nivation occurs in both the main valley and tributary valley.
-The main valley is eroded more than the tributary valley.
-The main valley is widened by lateral erosion and deepened by vertical erosion forming a glacial trough/ u-shaped valley.
-Ice melts and the tributary valley lies at a higher level than the main valley.
-The tributary forms the hanging valley.
