Answer:
e. To create valleys, glaciers have to be constantly advancing.
Explanation:
Although glaciers look like massive, solid blocks of ice, they actually move in a very slow manner, which is difficult to detect by the naked eye. The pressure that the glacier receives from the weight of the ice causes it to deform. As these changes occur, the melt water at the bottom of the glacier allows it to slide. It is this movement that allows for the formation of glaciers, as glaciers have to be constantly advancing in order to form valleys.
