Question

on which layer of the earth will the tectonic plates be found? the lithosphere the inner core the lower mantle

Explanation:

Tectonic plates are part of the Earth's rigid outer shell. The lithosphere includes the crust and the uppermost, rigid part of the mantle. The inner core is the solid innermost layer of the Earth, and the lower mantle is a more ductile layer beneath the upper mantle. Since tectonic plates move and interact, they must be in a rigid layer.

Answer:

the lithosphere
