100
A movement or trembling of the ground that is caused by a sudden release of energy when rocks along a fault move.
What is an Earthquake
100
The point on Earth’s surface directly above an earthquake starting point, or focus.
What is the epicenter
100
An instrument that records vibrations in the ground.
What is an seismograph
100
Liquid rock produced under Earth’s surface
What is magma
100
A vent or fissure in Earth’s surface through which magma and gases are expelled.
What is volcano
200
The sudden return of elastically deformed rock to its undeformed shape.
What is elastic rebound
200
A compression wave that causes particles on a rock to move in a back and forth direction.
What is a P wave
200
A tracing of earthquake motion that is recorded by a seismograph.
What is a seismogram
200
Any activity that includes the movement of magma toward or onto Earth’s surface.
What is volcanism
200
Magma that flows onto Earth’s surface, the rock that forms when lava cools and solidifies.
What is lava
300
The location within Earth along a fault which the first motion of an earthquake occurs.
What is the focus
300
A shear wave that causes particles of rock to move in a side to side direction.
What is a S wave
300
A measure of the strength of an earthquake
What is magnitude
300
A volcanically active area of Earth’s surface, commonly far from a tectonic plate boundary.
What is a hot spot
300
Describes magma or igneous rock that is rich in magnesium and iron and that is generally dark in color.
What is mafic
400
In geology, a seismic wave that travels through the body of a medium.
What is a body wave
400
An area on the Earth’s surface where no direct seismic waves from a particular earthquake can be detected.
What is shadow zone
400
A giant ocean wave that forms after a volcanic eruption, submarine earthquake, or landslide.
What is a tsunami
400
The three different types of volcanoes.
What are shield, cinder cone, and composite volcanoes
400
Fragments of rock that form during a volcanic eruption.
What is pyroclastic material
500
Using the following vocabulary; focus, epicenter, fault, and seismic waves, draw and label the anatomy of an earthquake.
What is me
500
An area along a fault where relatively few earthquakes have occurred recently but where strong earthquakes are known to have occurred in the past.
What is seismic gap
500
Body waves come in two forms; S waves and P waves, draw a diagram on how each waves moves through the earth's surface.
What is me
500
3 different types of lava flows.
What Pahoehoe, Aa, and Blocky
500
A large, circular depression that forms when the magma chamber below a volcano partially empties and causes the ground above to sink.
