Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Earth is made of different layers that have varying characteristics. Which is the thickest layer?
A
the mantle
B
the inner core
C
the outer core
D
the crust
Explanation: 

Detailed explanation-1: -The mantle is the mostly solid bulk of Earth’s interior. The mantle lies between Earth’s dense, superheated core and its thin outer layer, the crust. The mantle is about 2, 900 kilometers (1, 802 miles) thick, and makes up a whopping 84 percent of Earth’s total volume.

Detailed explanation-2: -Mantle is the thickest layer of earth at  2900km.

Detailed explanation-3: -Mantle-2, 900 km thick. Outer Core-2, 200 km thick. Inner Core-1, 230 to 1, 530 km thick.

Detailed explanation-4: -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-5: -The Earth’s crust is the outer layer of the Earth and is about 5 to 25 miles thick depending on its location. It is the thinnest layer, only about 3-5 miles thick under the oceans which is called the oceanic crust.
