How do the materials and design of Maya Lin's Disappearing Bodies of Water: Arctic Ice relate to its theme?

What will be an ideal response?

Answer: The ideal answer should include:
1. Its elevation on the granite pole suspends the marble ice layers over space, so it visually floats on air as though on water.
2. Its height above the floor and jagged, unsupported projections appear fragile and easily broken with any contact, although it is actually made of marble.
3. Although the multiple layers of the object represent different states of the ice in different time frames, the recessions also replicate the appearance of ice shelves as the edge of the Arctic landmass would actually appear if seen from the water.
