Here's a breakdown:

* Lithosphere: This is the rigid outermost layer of the Earth, composed of the crust and the uppermost part of the mantle. It's what we stand on, where mountains rise, and where rocks are found.

* Crust: This is the thin outer layer of the Earth, made up of different types of rock like granite, basalt, and sedimentary rock.

* Upper Mantle: This layer is primarily composed of solid rock but behaves more like a very viscous fluid over long periods.

So, the lithosphere, encompassing the crust and the uppermost mantle, is the part of the Earth that's rocky, inorganic, and primarily composed of different minerals.
