Wild Card
100
This type of volcano is named for its relatively flat and round shape.
What is a shield volcano?
100
This is the study of earthquakes.
What is Seismology?
100
Ocean floor spreading is caused by this type of plate boundary.
What is divergent?
100
Earth's crust "floats" on top of this "taffy-like" layer?
What is the mantle.
100
Before lava reaches earth's surface, it is referred to as this.
What is magma?
200
This phrase describes the series of volcanoes that exist around the Pacific Plate boundaries.
What is the Ring of Fire?
200
These vibrations are the first to be felt during an earthquake.
What are p-waves?
200
This boundary can be described as two plates sliding past on and other.
What is transform.
200
Earth's outer core is in this state of matter.
What is liquid?
200
Unlike magnitude, this is a measure of how much destruction an earthquake causes.
What is intensity?
300
This type of volcanic eruption tends to be relatively slow and gentle.
What is an effusive eruption?
300
This term refers to added supports given to walls or roofs.
What are trusses?
300
This is the term for when ocean crust goes under continental crust at convergent boundaries.
What is subduction?
300
Earth's magnetism is a result of the earth's core being made up of primarily these two elements.
What is Iron and Nickel?
300
The circulation of hot particles rising, cooling, and falling is known as this.
What is a convection current?
400
This term refers to a volcano that is currently inactive but could erupt some time in the future.
What is dormant?
400
This type of wave does not travel through liquid, which allowed scientists to determine that the earth's core was partially liquid.
What is an s-wave?
400
Scientists believe that that at one time all 7 continents were connected in this one Super-Continent.
What is Pangaea?
400
This is the term for the rigid outer part of the earth, consisting of the crust and upper mantle.
What is the lithosphere?
400
Unlike most volcanoes that form over plate boundaries, the Hawaiian islands were formed by these mid-plate features.
What are hot spots?
500
This volcanic hazard can be described as a mudflow or debris flow composed of a slurry of pyroclastic material, rocky debris, and water.
What is lahar?
500
This scale measures the magnitude of an Earthquake.
What is the Richter scale?
500
This German researcher is credited with the theory of Continental Drift.
Who is Alfred Wegener?
500
Convection in this upper layer of earth's mantle, causes tectonic plates to move and shift.
What is the asthenosphere?
500
This volcano erupted in 1991 in the Philippines causing widespread damage but less than 500 deaths thanks to an evacuation.
