Question

Earth's layering based on compositional VS mechanical properties, general composition of crust, mantle, core:

A. Compositional: Crust, Mantle, Core; Mechanical: Lithosphere, Asthenosphere, Mesosphere
B. Compositional: Mesosphere, Asthenosphere, Lithosphere; Mechanical: Crust, Mantle, Core
C. Compositional: Core, Mantle, Crust; Mechanical: Asthenosphere, Lithosphere, Mesosphere
D. Compositional: Crust, Core, Mantle; Mechanical: Lithosphere, Mesosphere, Asthenosphere

Answer 1

The layers based on compositional vs. mechanical properties of the Earth are Crust, Mantle, Core for composition and Lithosphere, Asthenosphere, Mesosphere for mechanical properties.

Step-by-step explanation:

The layers found inside Earth are divided by composition into the core, mantle, and crust, and by mechanical properties into the lithosphere and asthenosphere.

The correct answer is A. Compositional: Crust, Mantle, Core; Mechanical: Lithosphere, Asthenosphere, Mesosphere.

The Earth's crust is the outermost layer and is composed mainly of silicon oxide and aluminum oxide. The mantle is the layer beneath the crust and is predominantly ultramafic in composition, consisting of more iron, magnesium, and less aluminum and silicon than the crust. The core is the innermost layer and is primarily made up of iron and nickel.
