Answer:
(1)The climatic snow line is the boundary between a snow-covered and snow-free surface. The actual snow line may adjust seasonally, and be either significantly higher in elevation, or lower. The permanent snow line is the level above which snow will lie all year.
(2) a valley which has been cut across by a deeper valley or cliff.Hanging valleys are formed as a result of the erosion effects of glaciation. The valleys are thought to have been formed by two different glacier flows that interact with each other. A glacier with the relatively small amount of material flows into the main glacier with the more glacial material.
