Like enormous icebergs, mountains "float" on the underlying material (water for icebergs, the lithosphere for mountains). Which of the following is also true of both icebergs and mountains?
a. In both, tall, massive peaks correspond to broad, shallow roots.
b. In both, the underlying lithospheric material is free to flow and deform under the weight.
c. In both, the underlying material supports the mass through mechanical strength.
d. In both, a point of equilibrium has been reached between the displaced mass and the submerged mass.
e. In both, phase changes take place at approximately 373 kelvin.
Answer: D
