Question

which of the earths layers is broken into slabs called plates? lithosphere inner core outer core mesosphere

Explanation:

The lithosphere is the rigid outer layer of the Earth. It is divided into tectonic plates. These plates "float" on the more ductile asthenosphere. The inner core is the solid innermost layer of the Earth. The outer core is a liquid layer. The mesosphere is a part of the mantle below the asthenosphere. So the layer broken into plates (tectonic plates) is the lithosphere.

Answer:

Lithosphere
