Earthquakes (Ariana)
Earthquakes are caused when tension is relesed from the earths crust and upper mantle. this tension is due to friction between what scientists believe are large "plates" floating on magma on the earths serface.sometimes earthquakes happen when rocks in earths crust bend and break this causes shock waves to travel on the earths serface, resulting in widespread destruction!
