A Divergent plate boundary is when to plate move away form each other.While all that is happening the plates have so much stress that the plates start to pull and stretch rocks apart.Volcanoes and earthquakes along the oceanic ridge start to spread and form.The mid-atlantic ridge,east pacific rise and the East African Great Rift Valley is where it happens the most

Convergent plate boundarie is when two landforms collide together and form a mountain.The stress on the plates is because of the landforms clashing together and subduction happens.The subduction causes the magma to come up out of the mountain and makes a volcano.Deep trenches are often formed where tectonic plates are being subducted and earthquakes are mostly common.Here is some locations where it happens the Andes Mountain Range of western South America Cascade Mountain Range the Nazca Plate is subducting beneath the South American plate.

A Transform plate boundary is places where plates slide sideways past each other.As the plates are grinding past each other rocks start to break and earthquakes happen.Lithosphere is neither created nor destroyed.Many transform boundaries are found on the sea floor, where they connect segments of mid-ocean ridges.Here is a place where it mostly happens California's San Andreas fault on the seafloor.
