Volcano

A shield volcano is an alternating volcano. Ex. explosive or quiet

Quiet eruption, basaltic lava, layers, silica-poor

tephra falling into layers, andesitic lava, alternating explosions, silica-rich, silica-poor

falling tephra, steep-walled, loosely packed, granitic lava, explosive explosions, silica-rich

Hot spots slide under another plate and are underneath the ground

opening in Earth that erupts gases, ash, & lava

hot, melted rock material beneath Earth's surface

molten rock that flows from volcanoes onto Earth's surface

steep-walled depression around a volcano's neck

[blank_start]Hot spot[blank_end] is an unusually hot area between Earth's mantle & core that forms volcanoes when melted rock is forced upward & breaks through crust

A [blank_start]vent[blank_end] is an opening where magma is forced up & flows out onto Earth's surface as lava, forming a volcano

bits of rock or solidified lava dropped from the air during an explosive volcanic eruption

High amount of gas/silica-rich/BIG explosion

Low amount of gas/silica-poor/small explosion
