   Earthquake begins in the Earth's crust when stress has built up and suddenly the rocky layers rupture and then rebound. Earthquakes may be caused by moving plate boundaries. It is when there are convergent, divergent or transforms plate boundaries. In a convergent plate boundary, two plates will approach each other. The denser plate will then sub duct. Friction is produced and the ground shakes, depending on the strength of the quake, causing an earthquake. Shockwaves are radiated around the area, creating tremors. In a divergent plate boundary, two plates will move away from each other, causing the ground to sink, forming rift valleys. This will also cause earthquakes due to the sinking of land.
