What happens when heat from inside earth is transferred to its surface? a: warmer material is pushed to the crust b: more dense material is pushed to the outer core c: less dense material is pushed to the outer core

Option (A) is the correct answer.

Explanation:

Heat from inside the surface is transferred to its surface through conduction. As in conduction, there is transfer of heat from hotter substance to colder substance when placed together.

Therefore, less dense material rises towards the surface by the process of convection and more denser (colder) material remains inside the Earth.

Thus, we can conclude that warmer material is pushed to the crust.

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
