VOLQUAKE
100
The accepted theory that the outermost layer of earth consists of rigid plates that are in constant motion relative to each other.
What is plate tectonics
100
the sudden motion of earth as rocks break along the extensive surface within earth
What is an earthquake
100
a vent or fissure on earths crust
What is a volcano
100
the geographic point on earths surface directly above the focus.
What is an epicenter
100
is when a boundary created between two plates are moving away from each other
What is divergent
200
plates that move in relation to each other
What is lithospheric plates
200
the sudden release of energy as rocks rupture causing intense vibrations
What is seismic waves
200
a naturally occuring molten rock material generated within earth
What is magma
200
the source of abundant rising magma that forms volcanoes
What is Hot Spot
200
when two plates move alongside each other
What is transform
300
where do geologists claim that volcanoes are most commonly found
What is along the edges of certain continents
300
the vibrations that are inicially felt, and then the vibrations considered the "aftershock"
What is P-waves and S-waves
300
the cycle of hotter magma rising from the upper mantle, as the cooler magma falls onto the lower mantle.
What is Mantle Convection Current
300
scientists use this to predict earthquakes
What is seismic waves
300
tectonics comes from a greek word meaning
What is builder
400
the area that was created when convergence took place in the pacific ocean
What is Ring of Fire
400
the computer or paper record of seismic waves
What is seismogram
400
the point throught where the magma exits the volcano
What is the vent
400
when formations returns to its original state after a rupture took place
What is elastic rebound
400
The gradual movement of the continents across the earth's surface
What is continental drift
500
Results of plate tectonic movement
What is mountain ranges, islands, and mid-ocean ridges.
500
waves that can travel through solid
What is shear/secondary waves
500
what are the positive products of a volcanic eruption
What is valuable natural resources (soil fertility, etc)
500
Interaction of magma and what solution creates minerals that act like cement holding the earth together
What is water
500
the reason for plate tectonics or why the earths plates move
What is mantle convection
