True or False:Earth’s crust is one solid piece.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The outermost layer of the Earth is called as crust. It is not in one piece but fragmented. Each fragment is called as a plate.

Detailed explanation-2: -Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.

Detailed explanation-3: -The crust of the Earth is broken into many pieces called plates. The plates “float” on the soft, plastic mantle which is located below the crust. These plates usually move along smoothly but sometimes they stick and build up pressure. The pressure builds and the rock bends until it snaps.

Detailed explanation-4: -The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. There are two types of crust; oceanic and continental. Oceanic crust is denser and thinner and mainly composed of basalt.

Detailed explanation-5: -The lithosphere is the solid, outer part of Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
