Question

The figure below shows a cross-section through the Nisqually Glacier. The cross-section is projected onto a grid that shows the depth of the glacier and the horizontal distance along the surface of the glacier. The cross section also shows where a borehole (black solid line) was drilled vertically through the thickest part of the Nisqually Glacier to help measure how far and how fast the glacier is flowing down its valley. The borehole was surveyed two months later. The new position of the borehole after two months is shown by the dashed line. Examine the diagram above and then answer the questions that follow. AH answers should show work and include units. Examine the diagram above and then answer the question that follow. All answers should show work and include units. How thick is the Nisqually glacier? How far in total did the top of the glacier move in the two month period? Give your answer in meters.

Explanation / Answer
