Read the following statements carefully about interior of the Earth:
1. Asthenosphere is considered as source region of Mid-Oceanic Ridge Basalt.
2. Lower Mantle of the Earth’s surface is involved in plate tectonic movement and isostatic adjustments.
3. Oxygen is the most abundant element in the Earth’s crust.
Choose the correct answer using codes given below:
ANSWER: (C)
Asthenosphere is the highly viscous, mechanically weak and ductility deforming region of the upper mantle of the Earth. It lies below the lithosphere, at depths between approximately 80 and 200 km below the surface. It is upper portion of Mantle. It is considered the source region of mid-ocean ridge basalt. Crust and asthenosphere together make up Lithosphere. Asthenosphere is involved in plate tectonic movement and isostatic adjustments.
