What is this a picture of?
plate tectonics
continental drift

Scientists think that the continents once formed a giant landmass that broke apart, and then slowly drifted apart. What is the name given to this hypothesis?
sea-floor Spreading
plate tectonics
continental drift
Pangaea
Most geologist think that the movement of Earth's tectonic plates is caused by
the rotation of the Earth.
the Earth's magnetic field.
subduction.
convection currents.
Ocean crust is made of _______ and is _______ dense than continental crust.
basalt, less
basalt, more
granite, less
granite, more
Most tectonic plates have both oceanic and continental crust. How are they different?
Oceanic is thinner and less dense than continental.
Continental is thinner than more dense than oceanic.
Continental is thicker and less dense than oceanic.
Oceanic is thicker and more dense than continental.
Earthquakes are most common around plate boundaries.
True
False
Fossil records support continental drift.
True
False
Evidence of continental drift includes:
plants and animals match
the shape of the continents
the oceans are close together
rocks match
Ridges are the sites where plates move
together
apart
When plates collide we get ________.
crumbles
volcanos
trenches
mountain ranges
Tectonic plates consist of
continental crust
mesospheric crust
both continental and oceanic crust
oceanic crust
The region where two lithospheric plates meet
Continental Drift
Plate tectonics
Plate Boundaries
Pangaea was an ancient supercontinent made up of...
America, Greenland, and Europe
Antarctica, India, and America
all of Earth’s continents
South Africa, India, Australia, and South America
Why did no one believe Wegener's thoery that the continents were once together?
He could not explain HOW the continents moved
He didn't have evidence
His data was wrong
He didn't use the right technology to gather data
The movement of the tectonic plates is caused by
the rotation of the Earth
convection currents in the Asthenosphere
the gravity of the iron-nickel core
the Moho discontinuity
Which layer of the Earth consists of tectonic plates?
asthenosphere
mantle
mesosphere
lithosphere
Tectonic plates “float” on
the lithosphere
the mantle
the ocean
the asthenosphere
Which layer of Earth flows slowly and causes the crust to move?
Crust
Mantle
Inner Core
Outer core
When tectonic plates slide against each other causing the earth to move.
Subduction means.....
one plate goes under another plate
two plates slide past each other
two plate collide and form folded mountains
Sea-floor spreading explains how.....
new crust is created at a divergent boundary
volcanoes are formed on continents
deep sea trenches are formed
An opening on the Earth's crust through which hot molten rock flows out from deep inside the Earth.
Volcano
Fault line
Fold
Crater
What do we call an area where more then two plates interact in different ways
plate boundary zones
hot spots
convergent boundaries
subduction
Solid, outer layer and is made of both the oceanic and continental crust.
Hydrosphere
Core
Mantle
Crust
Hot fluid or semi-fluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.
Convection Current
Lithosphere
Core
Magma
The thick part of the earth's crust that forms the large landmasses. It is generally older and more complex than the oceanic crust.
Oceanic Crust
Continental Crust
Magma
Inner Core
In the region where two continental plates collide, what geological feature MOST often forms?
an ocean
a volcano
a river valley
a mountain chain
Crustal plates that pull apart from one another MOST likely form
volcanic island arcs
strike-slip faults
oceanic trenches
rift zones
Which of these tectonic plate boundaries is most likely to form a volcano.
a continental plate colliding with a continental plate
an oceanic plate sliding past a continental plate
a continental plate sliding past a continental plate
an oceanic plate colliding into a continental plate
Which statement best describes why fossils of the same land-dwelling species have been discovered in both South America and Africa?
The organism migrated to two continents
The organisms were separated by the formation of new mountain ranges
The organisms became extinct due to climate change on these continents
These organisms once lived on one large landmass that later split into two continents
What landform would most likely form at this plate boundary? Choose 2 correct answers.
mountains
volcanoes
trenches
mid-ocean ridges
This type of crust is thick, less dense, and made mostly of granite.
continental crust
oceanic crust
convergent boundary
divergent boundary
This type of crust is dense, thin, and made of basalt.
continental crust
oceanic crust
convergent boundary
divergent boundary
Match the following words with their definitions.
CORE
center made of Iron & Nickel
CRUST
part of the Earth we walk on
ASTHENOSPHERE
contains thick liquid, plates move here

The San Andreas Fault in California is a...
Convergent Plate Boundary
Divergent Plate Boundary
Transform Plate Boundary
The San Andreas fault in California is a transform fault. Students were asked to make maps predicting which way land would most likely move over thousands of years. Which one is correct?
