Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A deep well or mine shaft goes through which layer or layers of Earth?
A
crust only
B
mantle only
C
crust and mantle
D
mantle and core
Explanation: 

Detailed explanation-1: -Even the deepest coal mines and water wells, though, barely scratch the surface of what lies beneath Earth’s outer layer, called the crust. Below the crust lies the mantle, which is semi-solid and consists of rock and magma that moves about. Below the mantle, you’ll find Earth’s core, which is made up of two parts.

Detailed explanation-2: -Beneath the oceans, the crust varies little in thickness, generally extending only to about 5 km. The thickness of the crust beneath continents is much more variable but averages about 30 km; under large mountain ranges, such as the Alps or the Sierra Nevada, however, the base of the crust can be as deep as 100 km.

Detailed explanation-3: -The mantle lies between Earth’s dense, super-heated core and its thin outer layer, the crust.

Detailed explanation-4: -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-5: -The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere.
