Question

Quizplus · Accepted Answer

Glacial rebound and a superplume are both forms of epeirogeny, which refers to the vertical movement of the Earth's crust. Glacial rebound occurs when ice sheets melt, reducing the pressure on the Earth's crust and allowing it to rise. A superplume, a massive upwelling of magma, can also cause the crust to rise. Both processes are related to the vertical movement rather than the processes described by the other options.
