Answer:
In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions. Materials made of metal are common electrical conductors.
Explanation:
Electric conductivity is the movement of electrically charged particles. All metals conduct electricity to a certain extent, but certain metals are more highly conductive. The most highly conductive metals are silver, copper, and gold. Copper, for example, is highly conductive and commonly used in metal wiring.
Answer:
c. when large cracks open in the Earth's crust swallowing structures and people
Explanation:
Earthquakes is one of the natural events common is most areas of the earth leading to destruction of lives and properties. It varies from magnitude to level of impact which could range from mild, medium and heavy impact.
<em>The actual destruction of the properties is not the vibration that occurs during earthquakes but rather the opening of the earth crust leading to failure of structures found within that area. For example, building crashes etc.</em>
The answer is: lithosphere
Earth's crust, called the lithosphere, consists of 15 to 20 moving tectonic plates
Comets are cosmic snowballs of frozen gases, rock and dirt that orbit the Sun. once frozen, they're the dimensions of a small city. when a comet's orbit brings it about to the Sun, it heats up and spews dirt and gases into an enormous glowing head larger than most planets.
Hope it helps!<3
