Tectonic plates consist of
continental crust
mesospheric crust
both continental and oceanic crust
oceanic crust
The idea that the continents were once part of a single landmass that broke apart and
moved is
Continental Drift
Tectonic Plates
Transform
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
Tectonic plates “float” on
the lithosphere
the mantle
the ocean
the asthenosphere
The fact that similar fossils are found on both sides of the ocean is evidence of
magnetic reversal
global positioning
continental drift
oceanic drift
Who is the scientist who proposed Continental Drift Theory?
Alfred Wegener named his single supercontinent ____________, which means "all Earth" in ancient Greek.
Pandora
Gandowandaland
Pangea
Percia
What type of fossils were noticed by Wegener to be found on two different continents?
Most geologists 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.
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
outer core, inner core, crust, mantle
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.
Hot Spot
Fault line
Fold
Crater
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
