Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the rigid layer of the Earth’s surface made up of the crust and upper mantle called?
A
asthenosphere
B
lithosphere
C
mesosphere
D
continental crust
Explanation: 

Detailed explanation-1: -The lithosphere is the solid, outer part of Earth, extending to a depth of about 100 kilometers (62 miles). The lithosphere includes both the crust and the brittle upper portion of the mantle. The lithosphere is both the coolest and the most rigid of Earth’s layers.

Detailed explanation-2: -The lithosphere is the rocky outer part of Earth. It is made up of the brittle crust and the top part of the upper mantle. The lithosphere is the coolest and most rigid part of Earth.

Detailed explanation-3: -The mantle lies below the crust and is up to 2900 km thick. It consists of hot, dense, iron and magnesium-rich solid rock. The crust and the upper part of the mantle make up the lithosphere, which is broken into plates, both large and small.

Detailed explanation-4: -The crust of the Earth is called as lithosphere. This layer is composed of the mantle and the crust. Most part of the Earth’s crust is covered by the oceans.

Detailed explanation-5: -The lithosphere (litho:rock; sphere:layer) is the strong, upper 100 km of the Earth. The lithosphere is the tectonic plate we talk about in plate tectonics. The asthenosphere (a:without; stheno:strength) is the weak and easily deformed layer of the Earth that acts as a “lubricant” for the tectonic plates to slide over.
