Answer:
The rigid, solid layer of the upper mantle that is connected to the crust is called Lithosphere.
Explanation:
The different layers of Earth are crust, mantle and core. Crust is the thin outer portion of the planet. Mantle is the thick, dense layer of rock underneath the crust, which is solid near the top and partially melted beneath the surface. The lithosphere includes the crust and outer rigid portion of the mantle while the partially melted portion of the mantle is called the asthenosphere.
The atmosphere of earth is a gaseous layer which surrounds the earth and protects the life on earth. The five layers of atmosphere are troposphere, stratosphere, mesosphere, thermosphere and exosphere, where mesosphere is the third highest layer of the atmosphere.
