Earthquakes

By Charlie Gribble

What are Earthquakes?????

A sudden and violent shaking of the ground, sometimes causing great destruction. Or a Sesmic wave released beneath earth.

How and where they happen?

Earthquakes happen near plate boundaries and most major earthquakes happen near the pacific ocean.
