Evelyn is making a model of Earth to show how the physical layers correspond to the compositional layers. Which of the following should Evelyn show in her model? The physical layers exactly match the compositional layers.-A

The crust is the only compositional layer not included in the physical layers. -B

The physical layers of the inner core and outer core form a single compositional layer. -C

The physical layer of the asthenosphere includes the compositional layer of the crust.-D
on a test need it asap.
I'll report u if u don't give the answer and just want the points.

B

Explanation:

asthenosphere and convection

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
