Question

the layer of the earth that is composed of large plates that interlock and move over time is the
○ upper mantle
○ asthenosphere
○ outer core
○ ionosphere

Explanation:

The lithosphere is the rigid outer layer of the Earth, composed of the crust and the uppermost part of the mantle. It is divided into large tectonic plates that interlock and move over the more fluid asthenosphere. The outer core is a liquid layer, the asthenosphere is semi - fluid (not composed of large plates in the same rigid sense as the lithosphere), and the upper mantle (as a general term without specifying the lithospheric part) doesn't have the plate - like structure described.

Answer:

lithosphere
