Question

The earths crust is part of which sphere

Answer 1

The correct answer that would best complete the given statement above would be LITHOSPHERE. The Earth's crust is part of the lithosphere. The lithosphere is the sphere that includes the land part of the earth. It is the outer, solid, rocky crust covering the Earth. 

Answer 2

Lithosphere (‘litho’ for land). It is made of the crust and the top layer of the mantle. The lithosphere is broken into large pieces (tectonic plates). Its surface is characterized by various landform features. The lithosphere is divided into the crust (is made of loose soil and rocks), the mantle, the outer core, and the inner core.
