100
Most volcanoes occur in linear patterns.
What is the global distribution of volcanoes?
100
Tectonic plates move about this distance every year.
What is two centimeters?
100
The fracture in rock along which rock masses move relative to one another parallel to the fracture.
What is a fault?
100
In the rock cycle, this is the process magma goes through to change from liquid rock to a solid igneous rock.
What is cooling?
100
The theory that the Earth's crust and mantle are broken into massive pieces that travel in different directions and different speeds over the Earth's surface.
What is Plate Tectonics?
200
Of these locations, where would you least expect to see volcanic activity: Ring of Fire, California, Michigan, Iceland
What is Michigan?
200
The supercontinent that existed 250 million years ago.
What is Pangea?
200
The sudden release of slowly accumulated strain in crust, causing seismic waves to pass through the crust, possible causing damage on the surface of the Earth.
What are earthquakes?
200
Plate movement at a mid ocean ridge.
What are diverging oceanic plates?
200
Nearly 80% of earthquakes happen in this area.
What is the Ring of Fire - (Area ringing the Pacific Ocean)?
300
These are the result of volcanic eruptions onto mountainsides covered with ice and snow.
What are Lahars?
300
The cause of volcanoes that are not located near a plate boundry.
What is a hot spot?
300
The point within the Earth where a rupture first occurs to cause an earthquake.
What is the focus?
300
Which of the following do volcanoes NOT contribute to the water cycle: --Volcanoes emit water vapor into the atmosphere. --Groundwater circulates within volcanoes and becomes heated. -- All of the oxygen in the air we breathe originally comes from volcanoes.
What is all the oxygen we breathe originally comes from volcanoes?
300
Up and down rolling motion you would feel on the ground during an earthquake.
What are surface waves?
400
This volcanic hazard can affect communities hundreds of kilometers away from the site of a volcano.
What are Ash Flows?
400
The accepted primary mechanism for sea floor spreading.
What are convection currents in the mantle?
400
The point directly above the focus on the Earth's surface. This point is determined by studying data from at least 3 seismic data collection centers.
What is the epicenter?
400
The cause of Mount Everest growing taller each year.
What are colliding continental plates?
400
Large waves caused by underwater earthquakes or volcanic eruptions.
What is a Tsunami?
500
Which of the following would increase the speed of the flow of magma: An increase in viscosity an increase in silica content An increase in temperature of the magma
What is an increase in the temperature of the magma?
500
The outermost layer of the Earth consisting of the crust and upper mantle.
What is the lithosphere?
500
A measure of the amplitude of seismic waves. A one point increase is equal to a 10 times increase in intensity on this scale.
What is the Richter Scale?
500
There are two earthquakes. One measures 7.0 on the Richter Scale and the other 9.0. The amplitude of the second earthquake is how many times larger that the first?
What is 100?
500
The best two teacher in the world! (get this wrong and you WILL repeat 8th grade next year!)
Do you really have to ask the question!
