Explain the concept of isostatic rebound, and cite evidence for rebound that has occurred since
the end of the Pleistocene. What will be an ideal response?
Isostatic rebound is the vertical recovery of continental crust to its former elevation after the
melting of an ice sheet. Driven by adjustments in the upper mantle, the recovery is slower than
the disappearance of the ice. Evidence for isostatic rebound includes Scandinavian docks, which
were stranded above sea level as that landmass rose. There is also uplift of the Great Lakes
region.
