What is the science in which earthquakes are studied called?
What is seismology
100
A vent or fissure in the Earth’s surface through which magma and gases are expelled is called a(n)
What is volcano
100
When you talk about the viscosity of lava, you are talking about
What is how the lava flows.
100
Most active volcanoes form
What is where tectonic plates collide.
100
A benefit to society of volcano research is that it allows scientists
What is to better predict when eruptions will occur.
200
What do seismologists use to determine when an earthquake started?
What is a Seismogram
200
Where are volcanoes most likely to form?
What is along plate boundaries
200
Cool, stiff lava that forms jumbled heaps of sharp chunks near the vent is called
What is blocky lava
200
The depression created when the roof of a magma chamber collapses is called a
What is caldera
200
One of the active volcanoes on the island of Hawaii is named Kilauea. If Kilauea is a shield volcano, which of the following would be a reasonable inference? A. Kilauea formed from repeated eruptions of low viscosity lava. B. Kilauea formed from repeated moderately explosive eruptions of pyroclastic material. C. Kilauea is primarily made up of alternating layers of lava and pyroclastic material. D. Kilauea has formed a cinder cone through repeated eruptions of high viscosity lava.
What is A. Kilauea formed from repeated eruptions of low viscosity lava.

What causes the ground to move during an earthquake
What is elastic rebound
300
Molten rock deep underground often gathers in a
What is magma chamber
300
Which type of pyroclastic material gets its name from a word that means “little stones”?
What is lapilli
300
The volcanoes of Hawaii and other places far from tectonic plate boundaries are known as
What is a hot spot
300
Which of the following describes the relationship between plate movement and volcanoes? A. About 80% of active volcanoes on land form where plates collide, and about 15% form where plates separate. B. Plate tectonic movement and the resultant convergent and divergent boundaries allow magma to reach the surface and form volcanoes. C. The Ring of Fire contains almost 75% of active volcanoes on land. D. All of the above.
What is all of the above.
400
The greatest earthquake damage happens at the
What is epicenter
400
Lava that is very runny probably
What is has a low silica content.
400
Pyroclastic material forms when
What is magma explodes into the air and hardens.
400
a funnel-shaped pit
What is a crater

When magma builds up beneath a volcano, a large amount of pressure is created. What form does this pressure take? A. kinetic energy B. chemical energy C. potential energy D. explosive energy
What is potential energy
500
Earthquake waves that cause the ground to move up and down, much like ocean waves move water particles, are known as
What is surface waves
500
If the water content of magma is high,
What is an explosive eruption
500
Which category of volcano is most likely to erupt in the near future?
What is an active volcano
500
A tiltmeter is an instrument that measures
What are changes in a volcano’s slope.
500
In which of the following situations would there be the greatest amount of kinetic energy? A. just prior to eruption, when great pressure has built up inside a volcano B. during an explosive eruption in which pyroclastic material is blown high into the atmosphere C. just after an explosive eruption, when most of the debris has settled back to the ground D. long after an explosive eruption, when the volcanic debris has cooled and erosion of these deposits has started taking place
What is during an explosive eruption in which pyroclastic material is blown high into the atmosphere
