The observation that the continents fit together like puzzle pieces, and may once have been connected, led Alfred Wegener to propose a theory called
continental plowing.
continental drift.
wandering continents.
shape matching of continents.
Which of the following supported Wegener's theory?
Matching fossil plant remains found on two different continents.
Matching reptile remains found on two different continents.
Nearly identical sedimentary rock types of the same age in widely separated locations.
All of the above.
Scientists found that the continents were moving apart from each other due to magma rising out of mid-ocean ridges, and they called this
seafloor spreading.
seafloor rising.
changing seafloor.
underwater volcanoes.
Wegener's old theory, called seafloor spreading, was found to be too simplistic because it did not explain how the continents would move. It was replaced by a theory called
plate tectonics.
crustal forces.
paleomagnetism.
weather forces.
Plate margins are places where a lot of tectonic activity occur. Earthquakes occur, for example, along convergent margins, where plates are
moving apart.
sliding past each other.
colliding.
Which of the following best describes the location of the mantle?
Above the crust.
Between the crust and the lithosphere.
Between the crust and the core.
Beneath the core.
Which of the following plate interactions is most likely to form a mountain range?
A transform boundary between ocean plates.
A transform boundary between continental plates.
A convergent boundary between continental plates.
A subduction zone between a continental plate and an ocean plate.
The boundary at which crust is continually added is a
subduction zone.
transform boundary.
divergent boundary.
convergent boundary.
Subduction is when
earthquakes occur along a transform boundary.
new crust is formed.
one plate slides under another.
new islands are formed.
The mid-ocean ridge occurs along a
convergent boundary where new crust is formed.
transform boundary where crust is subducted.
divergent boundary where seafloor spreading takes place.
divergent boundary where subduction takes place.
When two continental plates pull apart a _________________ forms.
subduction zone
mountain range
earthquake
rift valley
Oceanic crust is _____________ than continental crust.
less dense
more dense
less hot
more hot
Continental crust is ________________ than oceanic crust.
hotter
colder

thinner
A place where an unusually hot part of the mangle rises through the crust causing volcanic activity is called a
divergent boundary.
hotspot.
convergent boundary.
transform boundary.
A map of global earthquakes and volcanoes tells you
where the edges of the continents are.
where the Earth is the hottest.
nothing; it is random.
where the plate boundaries are.
Which type of plate boundary does not cause volcanoes?
Convergent
Transform
Divergent
Which of the following occurs because of convection currents?
Tectonic plates move.
The mantle increases in size.
Pressure in the crust increases.
Pressure in the crust decreases.
