Question

all of the very thin crust (oceanic and continental) that makes up the entire surface of earth is which of these?
lithosphere
lower mantle
inner core

Explanation:

The lithosphere consists of the Earth's crust (oceanic and continental) and the uppermost rigid part of the mantle. The lower mantle is beneath the upper mantle and not the crust. The inner core is the solid innermost layer, far below the crust. So the thin crust (oceanic and continental) making up Earth’s surface is part of the lithosphere.

Answer:

lithosphere
