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...
