Magnesium oxide is the second-most abundant compound in this region. Convection in this region, which includes the asthenosphere, causes seafloor spreading, and it is believed to be the site of plumes that cause (*) volcanic hotspots. This region, which lies under the Moho discontinuity, makes up eighty-four percent of the Earth's volume. For 10 points, name this plastic solid region of the inner Earth below the crust.
Magnesium oxide is the second-most abundant compound in this region.
