Wooden stakes were placed in a glacier in a straight line as represented by A-A' in the diagram. The same stakes were observed later in the positions represented by B-B'. The pattern of movement of the stakes provides evidence that

glacial ice does not move

glacial ice is melting faster than it accumulates

the glacier is moving faster in the center than on the sides

friction is less along the sides of the glacier than in the center
