Volcanoes at spreading plate boundaries such as the Mid-Atlantic Ridge are non-explosive in nature. This is due to the fact that they are fed by very hot Basalt lava, which is very fluid in nature. This fluid quality means that they do not readily trap dissolved gasses to explosive levels, which is what makes certain types of volcanoes explosive in nature. The gasses are readily able to and easily escape from the magma once the pressure seal is broken and do not cause the popped champagne cork effect.

Why is it important for us to know about volcanoes?

Why do volcanoes erupt by boundaries the most?

Volcanoes often erupt at boundaries because this is where tectonic plates interact, causing intense heat and pressure to build up beneath the Earth's surface. This leads to the melting of rock and the formation of magma, which can eventually erupt as lava and volcanic ash through the volcano's vent.


Is Shield volcanoes found along subduction zones?

Cone volcanoes which are likely to erupt explosively are found at subduction zones. Spreading zones (constructive plate boundaries) and hot spots produce quieter volcanoes because their lava is thinner. The ones at hot spots are shield volcanoes.


Do earthquakes explode like volcanoes?

No, earthquakes and volcanoes are different geological events. Earthquakes are caused by the movement of tectonic plates beneath the Earth's surface, while volcanoes erupt due to magma or gas buildup beneath the Earth's crust. While both can cause destruction, earthquakes do not explode like volcanoes.
