Question

Mantle of the earth crust is ?

• A. A layer with the composition of semi-solid mineral matter
• B. A layer with the composition of fluid mineral matter
• C. A layer with the composition of semi-fluid mineral matter
• D. A layer with the composition of gaseous mineral matter

Hint:

Crust = solid, Mantle = semi-fluid, Outer core = liquid, Inner core = solid.

Answer 1

The Correct Option is C

1. Semi-solid mineral matter: closer to describing the rigid upper lithosphere, not the mantle overall.
2. Fluid mineral matter: this describes the liquid outer core, not the mantle.
3. Semi-fluid mineral matter: the mantle behaves as a viscous, semi-fluid layer that flows slowly, enabling plate movement.
4. Gaseous mineral matter: no part of the solid Earth exists in gaseous form.

The correct answer is A layer with the composition of semi-fluid mineral matter.
