Pahoehoe to Mineral: 25 terms
Pahoehoe: Hawaiian term for a smooth, rope-like lava flow
Seismic Wave: Mechanical waves of energy that move through the earth at different speeds
Tephra: Different sizes of volcanic material that get released from a volcano
Shield Volcano: Volcano formed from mafic magma that has a broad and fairly flat shape
P-wave: Fastest wave that will arrive first in an earthquake and can move through liquids, solids, and gasses
Strato / Composite Volcano: Volcano formed from andesitic magma that forms from oceanic and continental plates colliding1. Reverse Fault: A fault where the area above the plane of the fault has moved downward
Convergent: Boundary where two plates move together
Epicenter: Point on the earth's surface directly above where the earthquake formed
Alfred Wegener: German scientist who discovered continents fit together like puzzle pieces but had no evidence to support his idea
Normal Fault: A fault where the area above the plane of the fault has moved upward
Focus: Point inside the earth where the earthquake formed
Strike Slip Fault: A fault where two areas slide past one another
Isochrone: A line drawn on a map where all points on it represent the same time
Surface wave: Slow mechanical wave that reaches the surface of the earth
Divergent: Boundary where two plates move apart
Batholith: Largest igneous structure formed inside the earth
gneous rock: Formed by the cooling and crystallization of magma or lava
Intrusive: Formed inside the earth
Dike: Igneous structure that runs perpendicular to surrounding rock around it
Extrusive: Formed on the surface of the earth
Laccolith: Dome-shaped igneous structure
Intrusion: Igneous minerals forced between other layers of rock
Phenocrysts: Larger crystals surrounded by smaller grains/crystals in a rock
Sill: Igneous structure that runs parallel to surrounding rock around it
Mineral: Naturally occurring, inorganic, solid, crystalline substance that has a specific chemical composition
