Here's a breakdown:

* Lithosphere: This is the rigid outermost layer of Earth, consisting of the crust and the uppermost part of the mantle.

* Crust: The crust is the outermost layer of Earth, composed of relatively low-density rocks. It's divided into two types:

* Oceanic crust: Thinner and denser, made up primarily of basalt.

* Continental crust: Thicker and less dense, composed mostly of granite.

So, while the lithosphere includes both the crust and the uppermost mantle, the crust is the topmost layer.
