Earth Structure MCQ Test: The earth is made up of different layers, with each have a composition that makes it unique from the others. Did you know that the inner core is mostly made of liquid too hot that it melts iron? Each layer is a spherical shell that holds something different from the other, and as one goes deeper, the hotter it becomes. Take up this quiz and get to review what you know about the earth`s layer.

Why do most earthquakes take place at tectonic plate boundaries?
• A.

The rock in the interior of a tectonic plate is stronger, so it does not deform.

• B.

Earthquakes take place where energy is transferred to rock by the motion of tectonic plates.

• C.

Earthquakes can only occur at places where magma can reach the surface and transfer energy to rocks.

• D.

Earthquakes take place where a cold front meets a warm front.
