Why singapore has no valcanoes.
The reason why singapore has no valcanoes is because it does not sit in the pacific ring of fire. The pacific ring of fire is where all the valcanoes are. The pacific ring of fire goes around the pacific ocean...hence the name.

A popular way of classifying magmatic volcanoes is by their frequency of eruption, with those that erupt regularly called active,those that have erupted in historical times but are now quiet called dormant,and those that have not erupted in historical times called extinct.However te dormant and extinct volcanos are no use to the scientist because they only study active volcanos
Info
A volcano is an opening,in the earths or planets surface or crust,which allows hot,molten rock,ash,gases to escape from below the surface. Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a period of time.
Volcanoes are generally found where tectonic plates are pulled apart or come together.
Volcanoes can be caused by "mantle plumes". These so-called "hotspots" , for example at Hawaii, can occur far from plate boundaries. Hotspot volcanoes are also found elsewhere in the solar system, especially on rocky planets and moons.
