trench
Each of the plates may be oceanic or continental. That gives three possibilities:oceanic - oceanicoceanic - continentalcontinental - continental.
mountains can be created
Volcanoes and earthquakes
A trench and a island arc
Divergent boundaries.
They do if at least one of the plates is oceanic. If they are both continental, then a mountain range will form.
Convergent.
An example of convergent plate boundaries on earth is the Himalayas. :)
convergent boundaries collide but divergent boundaries move away from each other.
a mountain forms
Convergent Boundaries
The Convergent Boundaries are classifid according to the compass direction of movement of the plates.
