Word Up!
Huge pieces of crust and rigid upper mantle that fit together at their edges to cover Earth's surface.
Tectonic Plates
***Back and Forth***
Name the 3 types of convergent boundaries.
Oceanic-Oceanic
Oceanic-Continental
Continental-Continental
The numerical rating system that measures the energy of the largest seismic waves. It ranges from 1 to 10. 10 being the most severe.
The Richter Scale
*** Back and Forth***
Name the 3 types of Magma/Lava.
Andesitic
Basaltic
Rhyolitic
The size of seismic waves
Amplitude
Boundaries where 2 tectonic plates move apart.
Divergent
The Transfer of thermal energy by the movement of heated material from one place to another.
Convection
This type of wave is the most destructive because it causes the most movement of the ground.
Surface
This is the largest type of volcano.
Shield
A large ocean wave generated by vertical motions of the seafloor during an earthquake
Tsunami
Boundaries where 2 tectonic plates move toward each other.
Convergent
The theory that explains how new oceanic crust is formed at ocean ridges, slowly moving away from ocean ridges and destroyed at deep-sea trenches.
Sea Floor Spreading
The point of failure where earthquake waves originate.
Focus
***Back and Forth***
Name the 3 types of volcanoes
Cinder Cone
Composite
Shield
Unusually hot regions of Earth's mantle where high-temperature plumes of magma rise to the surface.
Hot Spots
The vibrations of the ground producing an earthquake
Seismic Waves
Another name for the Circum-Pacific Belt.
The Pacific Ring of Fire
This area includes Mt. Etna and Mt. Vesuvius.
The Mediterranean Belt
This forms when layers of solidified lava accumulates to form a mountain.
A Volcano
A long crack in Earth's crust.
Fissures
Measure of energy released during an earthquake
Magnitude
The German Meteorologist that developed the theory of Plate Tectonics in 1912.
Alfred Wegener
The result of the movement of crust and release of energy.
An Earthquake
This type of Magma/Lava erupts nonviolently.
Basaltic
An opening in Earth's crust through which lava erupts and flows out onto the surface.
Vent
