Question

Quizplus · Accepted Answer

Decompression melting occurs at mid-ocean ridges, where tectonic plates diverge and magma rises to form new oceanic crust. It also occurs at hotspots, where mantle plumes rise to the Earth's surface and melt due to decreased pressure. Subduction zones do not typically experience decompression melting because the descending plate is being compressed and heated, causing partial melting through other processes.
