Movements of tectonic plates against each other usually causing a jarring motion which causes an earthquake.

where plasma occur on the earth
no, they most likely occur wherever strong updrafts occur.
Volcanoes usually occur on a major tectonic plate boundaries. Most occur near the edges of a plate, some occur in the middle of the plate.

Upwellings
Upwellings in the oceans are associated with the bringing of very nutrient-rich waters to the surface. Those nutrients are the base of a food chain that includes fish. Areas of upwelling are usually extremely prolific fisheries.
Not per-Se, but plates pulling apart AND plates being overridden do cause magma upwellings.
how does upwelling bring fish and nutrients to the surface
The hot spots in the oceanic crust are caused by upwellings of hotter material (known as mantle plumes) in the mantle below the crust.
