Most of it is building the continental crust beneath our feet.
About 40% of Earth's surface is currently occupied by continental crust.

Subduction generally happens when ocean crust meets continental crust.
Here, the continental crust is weakened, and the magma can break through to the surface.
There is little evidence of continental crust prior to 3.5 Ga.
Today, most places are flat because that is the stable stage of the continental crust.
Such elements are relatively abundant in continental crust, but scarce in the mantle.

We're taught in Geology 101 that continental crust is buoyant and can't descend into the mantle,” Ingalls said.
Continental crust is produced and(far less often) destroyed mostly by plate tectonic processes, especially at convergent plate boundaries.
