composite
cinder cone
shield
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
volcano
vent
crater
hot, melted rock material beneath Earth's surface
magma
lava
hot spot

A 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
