A breaks-rather-than-flows asthenosphere, and a solid outer core.

Answer 1

Answer:

Option A is correct.

Explanation:

The lithosphere is the outer shell of the earth. It is composed of the crust and a portion of the upper mantle. It's broken into pieces that are known as tectonic plates. All solid-core planets possess a lithosphere.

The Asthenosphere is located right below the lithosphere, is highly viscous and even molten at some regions. Both the lithosphere and asthenosphere play crucial roles in the movement of the tectonic plates.

The solid inner core should not be confused with the outer molten core. The solid core is the innermost layer of earth. It is believed to be composed of an iron-nickel alloy with other elements. It has an estimated radius of 1221 km, and its temperature is believed to be of 5700K.
