It’s all your fault!
What is the fracture zone between stationary and moving rocks?
What is a fault?
What is the study of earthquakes?
What is seismology?
What is dormant?
This is lava that solidifies in water almost instantly, forming rounded structures.
What is pillow lava?
This is the most abundant element in the earth’s crust.
What is oxygen?
What type of fold occurs when rocks buckle up to form an arch-like structure?
What is anticline?
What is geology?
This type of mountain forms when molten rock erupts from a hole in the earth’s crust.
What is volcanic?
This is hardened lava with a surface that is either smooth or ropy.
What is magma?
What is the type of fault that occurs when rocks along one side of a fault move horizontally along the fault.
What is a strike-slip fault?
This instrument is used to record the vibrations caused by an earthquake?
What is a seismograph?
This kind of volcano consists primarily of erupted volcanic ash and rock fragments held loosely together.
What is a cinder-cone volcano?
This is solid ejecta that is larger than 2mm but less than 64 mm in diameter.
What is lapilli?
What is ingneous intrusion?
What major type of fault occurs when rocks on one side of the fault are shoved over the rocks on the other side?
What is a thrust fault?
An earthquake caused by sudden movements of rock beneath the earth’s surface is called this.
What is a tectonic earthquake?
The strength of a volcanic eruption is measured using a scale called what?
What is the Volcanic Explosivity Index (VEI)?
This is large, irregularly shaped lump made of lava that hardened before being thrown out of the volcano.
What is volcanic block?
The plastic rock on which the tectonic plates float is called the what?
What is the athenosphere?
What is the idea that rocks on either side of a fault spring to a position of little or no stress after an earthquake?
What is the elastic rebound theory?
The idea that rapid movement of tectonic plates during the Flood is responsible for most of the Earth’s features is called what?
This kind of volcano is formed partly by explosive eruptions of ash and rock fragments and partly by mild lava forms.
What is a composite volcano?
This type of ejecta is hardened lava that forms rough, jagged rocks with a crumbly texture.
What is aa?
A mass of underground volcanic rock that is similar to a laccolith but much larger is called what?
What is batholith?
