What is Pangea?
Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that
the oceanic crust is melting.
the denser oceanic crust is subducting under the less dense oceanic crust
volcanic islands are forming.
the tectonic plates are moving away from each other.
Where would sea floor spreading most likely occur?
At convergent boundaries (oceanic vs. oceanic)
At convergent boundaries (oceanic vs. continental)
At divergent plate boundaries (oceanic vs. oceanic)
At transform plate boundaries

What was the major flaw in Wegener's theory of continental drift?
What is the correct order (starting from the surface) of Earth’s layers?
crust, outer core, inner core, mantle
mantle, outer core, inner core, crust
crust, mantle, outer core, inner core

The youngest rocks on the ocean floor are located ____.
near continents
at mid-ocean ridges
far from mid-ocean ridges
near Asia
___________ is the hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations.
Continental drift
Sea-floor spreading
Plate tectonics
Mid-ocean range
What technology did scientists use in the mid-1900s to map the mid-ocean ridge?
satellites
deep-sea diving
submarines
sonar

The mesosaurus is an example of which type of evidence?
matching fossil
matching land formation
climate change
memorial movement
Which of the following was not used by Wegener as evidence of continental drift?
Evidences of glacial scratches continents found near the equator
Fossils that were found on different continents
Magnetic reversals on the seafloor
The fit of the continents
What did we learn from the ring of fire activity?
What evidence did Wegener use to support his theory?
Continents and fossils fitting together/matching-up like puzzle pieces
glacier scars and other climate evidence from temperature
mountain ranges and rocks line up across continents
all of the above
Wegener found fossils of land reptiles on two different continents. This was important because
Land reptiles are often found all over the world, showing that they can survive in most climates
Land reptiles cannot swim, so the continents must have been connected for them to get across
Land reptiles are never moved around the Earth by humans, so they must have travels to these continents by themselves
Land reptiles fossilized much better than other animal species
Wegener observed scratches from glaciers in Africa and India where it is currently too hot for glaciers to form. This is considered...
Fossil Evidence
Rock Formation Evidence
Climate Evidence
Objective Evidence
Wegener found fossils of ancient ferns on Antarctica, this shows
That some ferns can survive temperatures well below freezing
That humans put ferns on Antarctica millions of years ago
That Antarctica drifted from a warmer climate where plants could grow
That fossils can be formed in cold climates
The area around the pacific plate where boundaries form is called...
death ring
fire zone
ring of fire
zone of fire
The Hawaiian island chain is formed from a hot spot. As a result:
What is the significance of magnetic patterns on the seafloor?
What happens as an oceanic plate converges with a continental plate?
The oceanic plate is subducted beneath the continental plate
Why does an oceanic plate subduct under a continental plate?
From the ring of fire activity we learned volcanoes' and earthquakes usually occur where?
Plate boundary formed above a rising convection current in the mantle
Formed above a sinking convection current in the mantle.
Convergent /Subduction zone
What drives the convection currents in the mantle?
Heat transfer and differences in density
