deep earth
Far below surface
Deep earth refers to the regions far beneath the planet's surface—the mantle, outer core, and inner core that lie beyond the relatively thin crust.
The term appears in geology and planetary science: Deep earth processes drive plate tectonics.
It can also evoke burial or hidden depths: secrets buried in the deep earth.
