Volcanoes-place where magma reaches the surface of Earth

CRUST: the solid top layer of the earth, including the continents and the land under the oceans MANTLE: the liquid layer of the earth below the crust MAGMA: hot molten (liquid) rock below the earth’s surface LAVA: hot molten rock that flows from a volcano PLATES: large chunks of the earth’s crust that “float” on top of the mantle VENT: the opening through which volcanic material comes out CRATER: a large hole formed by the explosion or collapse of a volcanic vent LAVA LAKE: a pool of molten lava contained in a vent or crater HOTSPOT: area in the earth’s crust where magma rises and pushes through the surface

Magma • Forms wherever temperature & pressure are high enough to melt rock, i. e. the asthenosphere, plate boundaries • Less dense than solid rock near it, so moves upward through fractures • When magma reaches the surface it is called lava.

What determines the type of eruption? • Gases in Magma – Water vapor, carbon dioxide, hydrogen, sulfur – Amount of gas determines type of eruption – Large amount of gas = explosive eruption • Silica Content – Mafic: low silica, lava runs smooth, quickly – Felsic: high silica, lava runs more slowly, explosive, viscous (thick)

SHIELD VOLCANOES • Mafic lava =Low silica level • Low viscosity lava (thin) • High or low levels of gas • Flattened mound that resembles a warrior’s shield

MAUNA LOA, HAWAII Surtsey, Finland Piton de la Fournaise

COMPOSITE VOLCANOES Felsic lava = High in silica High viscosity lava (thick) High levels of gas/Highly explosive Cone shaped formed by layers of lava and volcanic fragments (ash, tephra)

Mt. Fuji, Japan MT. RAINIER, WASHINGTO N Mt. St. Helens, Washington

CINDERCONES Low silica lava High levels of gas Small - less than 300 m high “Fire-fountain” eruptions Made from a pile of rock pieces called tephra
