into which layer of the earth do plate boundaries extend? outer core lithosphere lower mantle asthenosphere
Answer
Brief Explanations:
Plate boundaries are located within the lithosphere. The lithosphere is divided into tectonic plates that move relative to each other. The outer core is a liquid - metallic layer far below. The lower mantle is more ductile and not where plate boundaries are. The asthenosphere is a semi - fluid layer beneath the lithosphere that allows the lithospheric plates to move, but plate boundaries are in the lithosphere itself.
Answer:
lithosphere
