If you are using the term 'upper crust' euphemistically and not to refer to bread or pies, then the upper crust is made of aristocrats. If you mean the upper part of the earth's crust, then it is made of the lightest elements from which the planet is made (silicon, aluminum etc).
The Asthenosphere is part of the Mantle of the Earth
Tectonic plates are formed from the lithosphere which is the solid brittle portion of the upper mantle and the crust so tectonic plates are part of both the crust and the upper brittle mantle.

lithenosphere
The lithosphere is made up of the crust and the upper part of the mantle. What do these layers of the lithosphere have in common? How are they different?

its made of a mantle, inner core, outter core and crust.......and a magnetic field. The interior is made up of the # crust # lithosphere (part of crust & upper mantle) # upper mantle # asthenosphere (more liquid-like part of mantle) # lower mantle # outer core (liquid ball) # inner core (solid ball) ...is what im pretty sure of
the lithosphere
The rigid layer that is the upper mantle and crust is called the lithosphere.
The solid portion of the upper mantle which behaves as a brittle solid is known as the lithospheric mantle. This part of the upper mantle along with the crust forms tectonic plates.
