The three types of stress on rocks.
What are tension, shearing, and compression?
100
The point within the Earth where the earthquake originates.
What is the focus?
100
The three types of seismic waves.
What are P waves, S waves, and Surface waves?
100
The four types of volcanoes
What are composite, cinder cone, shield, and lava dome?
100
This forms when magma cools and solidifies beneath the surface.
What are intrusions?
200
A fracture or zone of fractures between two blocks of rock.
What is a fault?
200
The point on earth's surface directly above the focus.
What is the epicenter?
200
An instrument that measures and records details of Earthquakes.
What is a seismograph?
200
This volcano has large symmetrical cones and explosive eruptions.
What is a composite volcano?
200
This is a powerful series of waves generated by an earthquake or landslide under the ocean.
What is a tsunami?
300
A quick movement along a fault line results in this.
What is an earthquake?
300
This scale measures the strength or magnitude of an earthquake from 1-10.
What is the Richter scale?
300
This is the fastest seismic wave.
What is a P wave?
300
This volcano resembles a warrior's shield. It is the largest volcano and its eruptions are not explosive.
What is a shield volcano?
300
Where 90% of the earth's volcanoes and earthquakes occur in the Pacific ocean.
What is the Ring of Fire?
400
The three main types of faults.
What are normal, reverse, and strike-slip?
400
This scale measures the intensity or severity of an earthquake from 1-12. It also describes what you might see and feel during an earthquake.
What is the Mercalli Scale?
400
This type of seismic wave results in most of the damage and destruction during an earthquake.
What is surface wave?
400
This type of volcano has small cones with steep sides. It is build over a short period of time.
What is a cinder cone volcano?
400
The two places where earthquakes are most likely to occur.
What are plate boundaries and fault lines?
500
The pent-up pressure of an earthquake is released as energy that radiates out in the form of ______________.
What are seismic waves?
500
Scientists measure this location by a method of triangulation. The _______________ is where three seismographs intersect.
What is the epicenter?
500
This is the second wave to arrive at a seismic station.
What is an S wave?
500
This volcano has lava too thick to flow a great distance. The thick lava piles up around the vent.
What is a lava dome volcano?
500
The three places where volcanoes occur.
What is convergent boundaries, divergent boundaries, and hot spots?
