Volcano Notes

1)What is the difference between lava and magma?? 2)What are the three places volcanoes are found? 3)What is pyroclastic debris? 4)What are the three types of volcanoes? 5)At which type(s) of boundary does each volcano form?

 Land or underwater feature that forms when magma reaches Earth’s surface

Lava = inside the Earth = on top of the Earth

The molten mixture of rock-forming substances, gases, and water that is inside the Earth

 Liquid magma that reaches the surface

Convergent boundary Divergent boundary Hot Spot

 Convergent boundaries  Divergent boundaries  Hot spots

 The result of an unusually hot area in Earth’s interior that forms volcanoes when melted rock is forced upward and breaks through the crust

“Pyro”= fire “clastic” = broken into little pieces

a fast-moving current of hot gas and rock

Stratovolcano

Mauna Loa, Hawaii (Big Island) Broad with a low, gentle slope Forms when very fluid (low viscosity) lava flows outward from the summit Found at divergent boundaries and hot spots

Capulin Volcano, New Mexico Small, loosely packed volcano Can be very steep but will erode over time At convergent boundary, divergent boundaries, or hot spots

Mt. Fuji, Japan Steep and wide The most deadly eruptions Form from layers of alternating lava flows, pyroclastic flows, and other debris Most common at convergent boundaries

1)What is the difference between lava and magma?? 2)What are the three places volcanoes are found? 3)What is pyroclastic debris? 4)What are the three types of volcanoes? 5)At which type(s) of boundary does each volcano form?
