eartquakes
as plates get caught together pressure builds up and then suddenly releases it causes an earthquake
the shockwaves are called seismic waves
seismic waves are measured with a seismometer
the size of the earthquake is measured in the Moment Magnitude Scale
olny happens at plate boundaries
structure of the earth
natural disasters
tsunami = really big wave
earthquake = ground shakes
volcano erupting = lava, rocks and ash come spewing out of the volcano
hurricane = massive storm with really fast winds
tornado = really fast winds
forest fire = everythings on fire
