Where do earthquakes and volcanos occur?

Answer 1

Volcanoes tend to form at convergent tectonic plate boundaries where subduction is occurring (such as the western coast of South America) and at divergent plate boundaries where two tectonic plates are moving apart (e.g. the Mid-Atlantic-Ridge and Iceland).

Earthquakes also occur at convergent boundaries and in fact these tend to cause the strongest earthquakes. Earthquakes also occur at transform boundaries (such as the San Andreas fault) however these do not tend to cause the formation of volcanoes.

So to find volcanoes and large earthquakes you should be looking at convergent plate boundaries where subduction is occurring.

Answer 2

mostly at the ring of fire

but volcanos and that occur around the tetonic plates

Answer 3

they occur over plate boundaries when 2 plates clash and one sinks and one rises

Answer 4

Under ground but they effect on ground
