Question
Select the false statement.
- The asthenosphere present below the lithosphere.
- The asthenosphere is mechanically strong.
- Outer core comprises of nickel, iron in liquid state.
- Gutenberg Discontinuity lies between the mantle and the outer core.
Hint:
Asthenosphere is not mechanically strong
The correct answer is: The asthenosphere is mechanically strong.
- The asthenosphere present below the lithosphere.
- Outer core comprises of nickel, iron in liquid state.
- Gutenberg discontinuity lies between the mantle and the outer core.
- But asthenosphere is the weak and easily deformed layer of the Earth that acts as a “lubricant” for the tectonic plates to slide over.
- So, the correct option is b.
