Yellow | | is molten rock that sometimes forms beneath the surface of the Earth |
Cascade Range | | is a chain of volcanic islands or mountains formed by plate tectonics as an oceanic tectonic plate subducts under another tectonic plate and produces magma. |
Supervolcano | | is an area of frequent earthquakes and volcanic eruptions encircling the basin of the Pacific Ocean |
Dacite | | is the result of a sudden release of energy in the Earth's crust that creates seismic waves |
dormant | | The month we are in |
Volcanic cones | | is an opening, or rupture, in a planet's surface or crust, which allows hot, molten rock, ash, and gases to escape from below the surface |
aftershock | | is an active volcano in the Hawaiʻian Islands |
Pumice | | is the solid outermost shell of a rocky planet |
epicenter | | are waves that travel through the Earth, most often as the result of a tectonic earthquake, sometimes from an explosion. |
March | | two plates move apart from each other and the space that this creates is filled with new crustal material sourced from molten magma that forms below |
Easter | | refers to heat sources within the planet |
Andesite | | is a roughly circular mound-shaped protrusion resulting from the slow eruption of felsic lava (usually rhyolite and/or dacite) from a volcano |
Lava | | What vocanoes do |

lithosphere | | Color of a school bus |
Tephra | | built by slow eruptions of highly viscous lavas |
Goodwin | | result from eruptions that erupt mostly small pieces of scoria and pyroclastics (both resemble cinders, hence the name of this volcano type) that build up around the vent. |

Coach Gates | | so named for their broad, shield-like profiles, are formed by the eruption of low-viscosity lavas that can flow a great distance from a vent, but not generally explode catastrophically |
maroon | | is another Greek term from Seism - "the shakes" and Graphos - "I draw |
Volcanology | | occur where two plates slide towards each other commonly forming either a subduction zone (if one plate moves underneath the other) or a continental collision (if the two plates contain continental crust). |
Richter | | is a planar rock fracture, which shows evidence of relative movement |
