200
A measure of earthquake magnitude
What is Richter Scale
200
consists of fragments of pulverized rock, minerals and volcanic glass, created during volcanic eruptions,

form when runny lava escapes through a fissure and flows a long way.
What is Composite volcanoes
200
A measure of earthquake magnitude
What is Richter Scale
200
a hard, unreactive, colorless compound that occurs as the mineral quartz and as a principal constituent of sandstone and other rocks.
What is Silica
300
the probable building damage, and number of people that are expected to be hurt or killed if a likely earthquake were to occur.
What is Earthquake Risk
300
hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this.
What is Magma
300
a broad, domed volcano with gently sloping sides, characteristic of the eruption of fluid, basaltic lava
What is Shield Volcano
300
fastest-moving type of seismic wave-causes push-pull motion
What is Primary Wave
300
the relatively thick part of the earth's crust that forms the large landmasses. It is generally older and more complex than the oceanic crust.
What is Continental Crust

a twelve-point scale for expressing the local intensity of an earthquake.
What is Mercalli Scale
400
a broad, domed volcano with gently sloping sides, characteristic of the eruption of fluid, basaltic lava
What is a Shield Volcano
400
a small area or region with a relatively hot temperature in comparison to its surroundings.
What is a Hot Spot
400
causes particles in the ground to move side to side and up and down at right angles
What is Secondary Wave
400
the center of interest or activity
What is focus
500
the center of interest or activity
What is Focus
500
form when runny lava escapes through a fissure and flows a long way.
What is Composite volcanoes
500
a dense, destructive mass of very hot ash, lava fragments, and gases ejected explosively from a volcano and typically flowing downslope at great speed.
What is Pyroclastic Flow
500
a twelve-point scale for expressing the local intensity of an earthquake.
What is Mercalli Scale
500
Dissolved amounts of viscosity that determines the explosiveness of magma
