Earthquakes
These are smaller earthquakes that follow larger earthquakes.
What is an aftershock?
This type of volcano is said to be inactive but could erupt again.
What is a Dormant Volcano?
This kind of mountain forms when molten rock erupts from a hole in the earth’s crust.
What is a Volcanic Mountain?
This is the study of the earth.
What is Geology?
This is molten rock beneath the surface of the earth.
What is Magma?
This is the study of earthquakes.
What is seismology?
This type of volcano will probably never erupt again.
What is an Extinct Volcano?
This type of mountain appears to have formed by edges of two adjacent tectonic plates pushing together.
What is a Folded Mountain?
This is the most abundant element in the earths crust.
What is oxygen?
These are the fastest type of earthquake waves.
What are Primary of P Waves?
This instrument is used to record vibrations caused by an earthquake.
What is a Seismograph?
This type of volcano consist primarily of erupted volcanic ash and rock fragments held loosely together.
What is a Cinder-Cone Volcano?
This is the point on the earth’s surface directly above where an earthquake begins.
What is Epicenter?
This is the earth’s outer layer which is made of solid rock.
What is Crust?
This is the middle of the earth’s 3 main layers.
What is Mantle?
This is the point deep in the earth where an earthquake begins.
What is Hypocenter?
This type of volcano is formed partly by explosive eruptions of ash and rock fragments and partly by mild lava flows.

This area contains about 80% of the world’s earthquakes.
What is the Circum-Pacific Belt?
This is the central portion of the earth.
What is Core?
This earthquake zone stretches from southern Europe to Indonesia.
What is the Alpide Belt?
This theory is the idea that rocks on either side of a fault spring into a position of little or no stress after an earthquake.
What is Elastic Rebound?
This is the channel in a volcano through which gases, ash, and molten rock are ejected from the earth’s interior.
What is a Vent?
This scale is used to measure the damage from an earthquake.
What is Modified Mercalli Scale?
This is the boundary line between the crust and the mantle.
What is Mohorovicic Discontinuity or Moho?
This type of earthquakes make up 85% of all earthquakes.
What are Shallow-Focus earthquakes?
