100

Vibrations caused by the rupture and sudden movement of rocks along a break or a crack in Earth's crust.

What is earthquake?

100

A scale that measures magnitude.

What is Richter Magnitude Scale?

100

Also known as a P-Wave, it is a type of seismic wave which causes particles in the ground to move in a push-pull motion similar to a coiled spring. These waves arrive first to a seismometer.

What is Primary Wave?

100
A volcano is a vent in Earth's crust through which molten rock flows.
What is volcano?
100
Why is ash beneficial to plants?
Ash is beneficial to plants because it contains minerals that the plants take in.
200

The location on Earth's surface directly above an earthquake's focus.

What is Epicenter?

200

Measures the total amount of energy released by an earthquake.

What is Moment Magnitude Scale?

200

Also known as a S-Wave, it is a type of seismic wave that causes particles to move at right angles relative to the direction the wave travels. These waves arrive second to a seismometer.

What is Secondary Wave?

200
The thickness of lava.
What is viscosity?
200
What type of flow moves at speeds of more than 100km/hr and have temperatures of 2000 degrees Celsius.
Pyroclastic Flows
300
A location inside Earth where seismic waves originate and rocks first move along a fault and from which seismic waves originate.
What is focus?
300
Evaluated the damage that results from the shaking of the earthquake.
What is Modified Mercalli Scale?
300

A type of seismic wave that causes particles in the ground to move up and down in a rolling motion.

What is Surface Wave?

300
Lava is magma that erupts onto Earth's surface. Magma is molten rock stored beneath Earth's surface.
What is lava and magma?
300
What is the most explosive volcano eruption?
The most explosive (and awesome) volcano eruption is the plinian eruption.
400

A crack or fracture in Earth's lithosphere along which one block of rock moves toward, away from or past another.

What is fault?

400
An instrument that measures and records ground motion and can be used to determine the distance seismic waves travel.
What is seismometer?
400

A seismometer is an instrument that measures and records ground motion and can be used to determine the dstance seismic waves travel. A seismogram is a graphical illustration of seismic waves.

What is Seismometer and Seismogram?

400
A hot spot is a location where volcanoes form far from plate boundaries.
What is hot spot?
400
What is the world's most active volcano?
The world's most active volcano is Kilauea in Hawaii.
500

Strike slip fault, normal fault, and reverse fault.

What is the three faults?

500
Richter Magnitude Scale, Moment Magnitude Scale, and Modified Mercalli Scale.
What is the three scales?
500

A seismic wave is energy that travels as vibrations on and in Earth.

What is seismic wave?

500
Shield Volcano, Composite Volcano, and Cinder Cone Volcano.
What are the three types of volcanoes?
500
Name the volcano that is in the United States that sent 250 cubic miles of material into the air. This volcano has also been vacant for 640,000 years.
The Yellowstone Supervolcano
