They don't form anything, when they meet they simply apply stress and strain upon each other until it becomes to stressful on them and one slips over or under the other and causes an earthquake.
The plates are moving towards each other and they collide.
Transform boundary is when the plates are sliding past each other: ↑ ↓; Divergent is when plates are sliding away from each other: ← →; and convergent is when plates are sliding towards each other: → ←. Those are the three main plate boundaries.
Transform. Transform boundaries are when two plates are moving horizontally past each other, neither destroying or creating crust. Just moving, minding their own business.
earth quake
Plates that move toasted each other are detractive plates meeting at a destructive margin. If a continental and an oceanic plate move towards each other, earthquakes and volcanoes occur, this is called a subduction margin, but if the plates are both continental then fold mountains form this is a collision margin
rift zone
the plates are moving away from each other.
it causes earthquakes!
They slide past each other horizontally.
A transform boundary is made when tectonic plates slide past each other.
earthquakes
transform boundary
oceanic/contintal
convergent
Plates either move towards each other (convergent plates), away from each other (divergent plates) or slide next to each other (transform plates).
convergent
that is the transform boundaries
