Where is the asthenosphere located?
A) in the inner core
B) in the outer atmosphere
C) in a plastic region in the crust
D) in a plastic region in the mantle
Asthenosphere
The semi-fluid layer of the Earth located below the lithosphere, allowing for plate tectonic movement.
Inner Core
The Earth's innermost layer, composed mainly of iron and nickel, solid due to extremely high pressure despite its high temperature.
Outer Atmosphere
The outermost layer of Earth's atmosphere, extending beyond the mesosphere, primarily composed of extremely low densities of hydrogen, helium, and other lighter gases.

Final Answer :
D
Explanation :
The asthenosphere is located in a plastic region in the mantle, specifically in the upper part of the mantle below the lithosphere. This layer is partially molten and has a reduced strength, allowing for the movement of tectonic plates.
