Here's a breakdown:

* Crust: The thin, outermost layer of the Earth, composed of various rocks. It's further divided into oceanic crust (thinner, denser, and younger) and continental crust (thicker, less dense, and older).

* Upper Mantle: The layer beneath the crust, composed of solid rock but capable of flowing over extremely long periods.

The lithosphere is broken into large pieces called tectonic plates, which float on the semi-molten layer beneath called the asthenosphere. These plates interact with each other, causing earthquakes, volcanic eruptions, and the formation of mountains and ocean basins.

Location: The lithosphere is located right beneath the surface of the Earth, encompassing the crust and a small portion of the upper mantle.

It's important to note that the lithosphere is not a continuous layer. It is broken up into numerous tectonic plates, which move and interact with each other.
