science earthquakes and layers

are vibrations of the earth’s crust caused by movement at plate boundaries and major fault lines.

• earthquakes

• tsunamis

• meteors

• typhoons

Where two plates meet

• tectonic plates

• plate boundaries

• fault lines

• conservative

the Earth’s crust is made of sections called (it is like a jigsaw puzzle)

it occurs with minor tremors (low magnitude). It happens before the main quake

an earthquake of less intensity that follows the main quake
