It's because the plates push up and up to make... drumroll please...
drumroll a volcano!
Along the tectonic plate boundaries.
along plate boundaries
transform and divergent
Earthquakes are likely to occur along tectonic plate boundaries where there is movement and stress in the Earth's crust. Volcanoes are likely to occur at convergent plate boundaries, divergent plate boundaries, and hotspots where magma from the Earth's mantle reaches the surface.
Shield volcanoes may occur far from any plate boundaries.
Volcanoes do not occur randomly over Earth's surface. They occur along the located mark of plate boundaries.
mhmmm (: its rarer though..
Most earthquakes occur on plate boundaries such as Japan and Chile and most volcanoes occur in diverging plate boundaries like Dallol and Iceland and the Pacific Ring of Fire like Ecuador and Indonesia
they are formed along the crustal movements of the earth.
Volcanoes
Volcanoes typically occur at two different types of plate boundaries. These two plate boundaries are: the diverging plate boundary where plates separate, and the converging plate boundaries where one plate is beneath another one at subduction zones.
Volcanoes at divergent plate boundaries often occur along mid-ocean ridges, where tectonic plates are moving apart. As the plates separate, magma rises to the surface, creating underwater volcanic activity. These volcanic eruptions contribute to the formation of new oceanic crust.
