Movements of tectonic plates causes collision. As these plates collide, some parts of it gets stuck while the rest of it keeps going.
Now, lets start with the basics. The outermost layer of Earth's lithosphere is composed of tectonic plates. In essence, each continent may be situated on one or two plates.
These plates movegradually because of the movement under the surface. The plate's edges arecalled plate boundaries.
Afterwards, faults appear. Faults are fractures where the crust has moved. Earthquakes happen as a result of this event.
So, Earthquakes are the sudden shaking of Earth's crust caused by released energy? And, what are the effects?
Basically, yeah! Im glad you got THAT figured out.
