The Four Main Types of Volcanoes Volcanoes vary in size and structure, depending on how they’re formed. Most volcanoes types fall into four main groups: Shield Volcanoes Shield volcanoes are built slowly, from low-viscosity lava that spreads far and quick. The lava eventually dries to form a...

Volcanoes are further classified by their shapes, their composition and their eruption patterns. The three main types are stratovolcanoes, shield volcanoes and scoria cones. Stratovolcanoes have steep upward slopes with a small crater at the top. Shield volcanoes are slightly sloped hills. Scoria con...

Many volcanoes have several vents –a main one, and secondary ones that branch off the main vent. The volcano’s main vent goes all the way down to the layer of magma in between the Earth’s crust and mantle. The Earth has three layers – the crust at the very top, then the mantle...
