According to plate tectonic theory and observations of seismic waves, the upper mantle is solid and more dense than the crust. At greater depth, the rigidity abruptly decreases and it becomes very flexible, but not liquid.
The upper mantle is less rigid because the pressure is lower
dirt and rigid rocks
The lithosphere is composed of the crust and uppermost mantle. Combined, they form the lithospheric plates.
Actually, the uppermost mantle is part of the lithosphere. The lithosphere consists of the crust and attached uppermost rigid mantle.
Lithosphere
The rigid layer that is the upper mantle and crust is called the lithosphere.
It is made up of the top, rigid layer of the mantle and the crust
Lithosphere
No. A tectonic plate is a segment of the rigid rocky outer shell of the Earth composed of the crust and the brittle uppermost mantle.
The upper mantle is less rigid because the pressure is lower

That would be the Lithosphere. :D
It's called the lithosphere.
