move close to each other
CONVERGENT BOUNDARIES
slide past each other

deepest part of the ocean
TRENCHES
How many meters does a Philippine trench deep
10,540
happens when the external forces stretch the lithosphere
DEEP FISSURE
fracture zone that forms a transform plate
TRANSFORM FAULT
this is when earthquakes send waves through earth
