Why does the earth get earth quakes?

Answer 1

The earth's crust is divided up into big chunks, and these chunks are essentially what we live on today. in between the chunks, where one meets another, there are lines running through the ground. These are called fault lines. Now, because the mantle is just molten lava, the crust just moves along as it pleases. When two chunks float around and rub up against one another, this causes vibrations on the fault lines. This also causes the ground to move and shake, what we call an earthquake
