The Mohororvicic (Moho) discontinuity separates ?

Correct option is D

The correct answer is (d) Earth’s Crust and the mantle.
· The Mohorovicic discontinuity, or Moho, is primarily known for marking the boundary between the Earth's lithosphere (which includes the crust and uppermost mantle) and the asthenosphere (a partially molten and ductile region in the upper mantle).
· The lithosphere is rigid and brittle, while the asthenosphere beneath it is more ductile and capable of gradual flow.
· The crust is the outermost solid layer of Earth, consisting of both continental and oceanic crusts.
· The inner core is a solid sphere of iron and nickel at the center of the Earth, beneath the mantle and outer core.
· The mantle is the layer beneath the crust extending to about 2,900 kilometers (1,800 miles) deep.
