Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 1 i.e.Crust (outermost)-mantle-core (innermost)

  • The correct sequence of layers of Earth from the outside of the planet to the inside is Crust (outermost)-mantle-core (innermost).
  • Crust: The outermost layer, where we live. The crust is the thinnest layer, varying from about 5 kilometers in thickness in the oceanic crust to about 30-70 kilometers in the continental crust.
  • Mantle: The thickest layer of the Earth, making up 68% of the total mass of the earth. The upper part of the mantle is known as the asthenosphere.
  • Outer core: A liquid layer located beneath the mantle.
  • Inner core: The deepest layer and the center of the Earth lies inside the inner core.
