divergent boundaries
This is where two plates move away from each other. Molten rock from the mantle erupts along the opening, forming new crust.
occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle.
convergent boundaries
oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate solidifying into granite the rock that makes up the continents.
When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges

Tremor
They also occur along the seafloor and cause it to move And if the quake is powerful enough, it can trigger waves that travel across the ocean.
