Which is the thickest layer of the earth?
A) Crust
B) Mantle
C) Outer Core
D) Inner Core
Correct Answer:
B) Mantle
Explanation:
The mantle is the thickest layer of the Earth, extending from just beneath the Earth’s crust to a depth of about 2,900 kilometers (1,800 miles) below the Earth’s surface. It makes up a significant portion of the Earth’s volume and consists of semi-solid rock that flows over geological timescales. The other layers, including the crust (option A), outer core (option C), and inner core (option D), are thinner layers beneath the mantle.
