Where are volcanoes found?
Volcanoes can be found all over the world but most are concentrated along plate boundaries. The majority of the world’s active volcanoes are located along convergent plate boundaries, especially around the Pacific Ocean. Most active U.S. volcanoes are located in Alaska or in the Cascade Range of Washington, Oregon and California. Volcanoes form from magma generated by the melting of plates descending into subduction zones. • Why are there volcanoes in Hawaii? The state of Hawaii is made up almost exclusively of volcanoes yet it is not located along a plate boundary. Hawaii is located above a hot spot in the mantle. Magma rising from the hot spot forms a line of volcanoes (Hawaiian island chain) as the overlying plate passes over the hot spot. How do Hawaiian and Cascade (& Alaska) volcanoes differ? Hawaiian volcanoes differ from Alaskan and Cascade volcanoes in their shape and style of eruption. Hawaiian volcanoes have broad gently sloping sides built up from lava produced during relat

Volcanoes happen all over the globe. Alaska, Iceland, Mexico, and Sweden: these are some of the places volcanoes are also found. Volcanoes are also found in weak places. The Ring of Fire is one of the major places to find volcanoes and they are also found around the edges of plates. When the plates make a divergent boundary, the plates make a crack, then the mantle s magma makes it s way through the crack. After there is enough pressure the magma is pushed through the top of the crack and then the magma is called lava.
