How are earthquakes related to the Earth’s moving plate tectonics?
A
The boundaries between the plates grind against each other, producing most earthquakes.
B
Earthquakes occur in the lithosphere, because this is where moving plate tectonics are located.
C
The ocean ridges are the asthenosphere spreading centers, creating new oceanic crust and earthquakes.
D
The movement of the plate tectonics and magma pushing up through the cracks in the plates cause earthquakes.
