divergent boundary

they make mid ocean ridges

Divergent boundary is a linear feture that exist between two tectoic plates that are moving away from eachother divergent boundary makes sea floor.

Convergent boundary real life example is 

convergent boundary

 Convergent boundary is an    actively deforming region where two or more tectioic       plate or fragments the convergent boundary makes volcanoes they destorye the seafloor

Plate Tectonics real life example is

 A theory explaning the strucer of the earth's crust and many associated.

 the plate boundary's make volcanos. they make deep ocean trenches
