The Earth does not have a "rigid" outer covering, it has an atmosphere.
Below the atmosphere is the crust which is made of tectonic plates. However there plates are NOT rigid and to describe them as such would be incorrect, they deform and fold.
The Earth's outermost sphere is the Lithosphere. It's the rigid outermost shell of the Earth.
Yes, the cool and rigid shell is the asthenosphere.
The lithosphere is the rigid outermost shell of a rocky planet. On Earth, it comprises the crust and the portion of the upper mantle
The Earth's outermost sphere is the Lithosphere. It's the rigid outermost shell of the Earth.
The asthenosphere is the weaker, hotter zone beneath the lithosphere that allows for the motion of Earth's rigid outer shell. Its semi-fluid properties enable the lithospheric plates to move and interact with each other.

the atmosphere
Yes. Well, more or less rigid.
The Earth's outermost sphere is the Lithosphere. It's the rigid outermost shell of the Earth.
The rigid shell or case of protozoans and rotifers is called a lorica. It provides protection and support for these microorganisms.
Yes. Well, more or less rigid.
Yes, the cool and rigid shell is the asthenosphere.
