Divergent is a type of a plate boundary.
In divergent boundaries, earthquakes occur, where two plates are being pushed away from each other. Therefore, hot magma rising under the crust pushes itself towards the surface of the earth and pressure caused by this, is enough to push the plates away from each other and causes a giant tremor under the earth. This produces a local earthquake and these are constantly cause along the Mid-Atlantic Ridge.
Convergent is a type of a plate boundary.
In convergent boundaries, the oceanic plate is subducted under either continental plate or another oceanic plate. Those power builds up and eventually, the plate on the top suddenly moves. This movement causes the earthquake. The longer plate is stuck, more powerful the earthquake is while the plate breaks free. This earthquake is caused a lot, under Southern British Columbic.
Again, transform fault is another type of a plate boundary.
In transform fault boundaries, two plates moving really fast towards each other get stuck. The power builds up until one plate abruptly and unexpectedly move. When this happens the transform fault boundary earthquake occurs. This type of earthquake occurs a lot along the San Andreas Fault in California.
Almost all the volcanoes on land are placed near convergent plate boundaries. Some of the most powerful volcanoes erupt where a plate is being subducted under another plate. Magma that is formed in a subduction area is sticky and thick
