Which term describes a section of Earht's structure below moving continents as parts of large plates?

Answer 1

"Asthenosphere" describes a section of Earth's structure below moving continents as parts of large plates.

Answer: Option C

Explanation:

The asthenosphere denoted as the upper mantle of a very sticky, mechanically weak and flexible area in the earth. It is located below the surface of the lithosphere at depths of about 80 and 200 km (in terms of miles, 50 and 120). The boundary is commonly called the lithospheric LAB - asthenosphere.

The asthenosphere is nearly solid, though some of its regions could be molten below mid-ocean ridges for an instance. The lower asthenosphere boundary isn't well defined. The asthenosphere's thickness depends primarily on the temperature.
