The theory that parts of the Earth's crust slowly drift atop a liquid core.
What is continental drift?
100
The remnants of deceased organisms.
What are fossils?
100
The unit in which severity of earthquakes is measured.
What is magnitude?
100
Convergent, divergent, and transform.
What are the different types of plate boundaries?
100
Molten rock above the earth’s surface
What is lava?
200
Look-alike animal and plant fossils, and similar rock formations, are found on different continents.
What is evidence for the theory of continental drift?
200
Sedimentary, metamorphic, and igneous.
What are the different types of rock?
200
The tool used to measure the severity of an earthquake.
What is a seismograph?
200
The San Andreas fault is an example of one.
What is a transform boundary?
200
The sound of a volcano
What is Psh (or something along the lines of it)?
300
Alfred Wegener, a geophysicist and meteorologist.
Who is responsible for the theory of continental drift?
300
Marble is an example of this type of rock.
What is metamorphic rock
300
The point on the earth’s surface where the earthquake starts.
What is the epicenter?
300
Inner Core, Outer Core, Mantle, and Crust, in that order.
What is the organization of Earth’s layers from most to least dense (or inner to outer)?
300
Molten rock under the earth’s surface
What is magma?
400
It was a supercontinent that existed due to continental drift during the late Paleozoic and early Mesozoic eras.
What is Pangea
400
It is an igneous rock.
What is andesite, basalt, obsidian, pumice, rhyolite, scoria, tuff, etc.
400
The point under the surface of the earth where the earthquake starts.
What is the focus?
400
A geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another.
What is subduction?
400
A vent in the earth’s crust from which gasses and and molten rock erupt.
What is a volcano?
500
The Mesosaurus, which is an ancient organism, long extinct.
What is one fossil that has been proven to point to evidence of continental drift?
500
Rocks from Argentina are identical to rocks found in South Africa.
What is a piece of evidence for continental drift?
500
The magnitude in which the majority of buildings destroyed extend to 250 km radius from the epicenter.
What is a 7 on the Richter scale?
500
It occurs in the Asthenosphere, which is below the lithosphere, and has low resistance to plastic flow.
Where do convection currents occur?
500
The three main types of volcanoes
What are Shield, strato-composite, and cinder cone volcanoes?
