Alfred Wegener’s idea of continental drift was not complete because he didn’t know...
that the continents moved.
that the continents looked like puzzle pieces.
how the continents moved.
about Pangaea.
Which type of plate boundary is pictured?
transform boundary
divergent boundary
convergent boundary
tectonic plates
What process is happening at Z?
Pangaea
magnetic reversal
sea-floor spreading
subduction
Why does oceanic crust subduct under continental crust when the two converge?
Oceanic crust subducts under continental crusts because they have the same density.
Oceanic crust subducts under continental crusts because oceanic crust is more dense than continental crust.
Oceanic crust subducts under continental crusts because oceanic crust is less dense than continental crust.
Oceanic crust does not subduct under continental crust.
What ocean floor feature occurs at X?
a. an island
a. a trench
a. the mid-ocean ridge
a. an underwater cave

. Which type of plate boundary is pictured above?
transform boundary
divergent boundary
convergent boundary
tectonic plates
According to the theory of plate tectonics, on which layer of Earth do plates float?
asthenosphere / mantle
lithosphere / crust
crust
core
The moving plates of Earth's lithosphere cause all of the following except
earthquakes.
volcanoes.
hurricanes.
mountains.
The giant continent which was composed of all the land on Earth was called
Pangaea.
Panthalassa.
Gondwana.
Laurasia.
A collision between two pieces of continental crust at a convergent boundary produces a
mid-ocean ridge.
deep-ocean trench.
rift valley.
mountain range.
The geological theory that states that pieces of Earth's lithosphere are in constant, slow motion is the theory of
subduction.
plate tectonics.
deep-ocean trenches.
sea-floor spreading.
Earthquakes and volcanoes are primarily found
at the mid-ocean ridge.
in California
along plate boundaries.
along the equator.
How does fossil evidence support Wegener’s hypothesis of continental drift?
Similar fossils found on far apart landmasses suggest that the continents were once a single land mass.
Fossil evidence suggests that the continents have always been in their current positions.
No similarities exist between fossils on different continents.
Plant and animal fossils show evidence of changes in earth’s polarity.
Geological processes (like water or lava flowing) CAN change Earth's surface.
True
False
Which of the following is the correct definition for Lithosphere?
the rigid outer part of the Earth, consisting of the crust and upper mantle
the outermost region of the planet's atmosphere
the Earth's layer of silicate rock between the crust and outer core
the soft layer of the mantle on which tectonic plates move
What is the soft layer of the mantle on which the tectonic plates move?
Asthenosphere
Mesosphere
Lithosphere
Hydrospere
