What evidence was NOT used by Wegener as proof of continental drift?
land features
erosion
climate
fossils
What is a plate boundary where both plates move away from each other?
divergent
plate
convergent
transform
Any trace of an ancient organism that has been preserved in rock is called a
landform
continent
fossil
landmass
According to Wegener's theory of continental drift,
Earth's surface is made up of seven major landmasses
the continents do not drift
Earth is slowly cooling and shrinking
the continents were once joined together in a single landmass and have slowly moved.
What is Pangea?
the name of a German scientist
the name of a supercontinent that existed millions of years ago
another name for continental drift
the name of an ancient fossil
What are breaks in Earth's crust where rocks have slipped past each other?
sea floor spreading
subduction
plates
faults
What is the process that continually adds new crust to the ocean floor along both sides of the mid-ocean ridge?
subduction
continental drift
convergent
sea floor spreading
What is a plate boundary where two plates move toward each other?
transform
convergent
divergent
What is a plate boundary where two plates slip past each other moving in opposite directions?
transform
convergent
divergent
What type of landform is at C?
mid-ocean ridge
continental crust
deep ocean trench
sea floor spread
In sea floor spreading, molten material rises from the mantle and erupts
along the edge of the continents
along the mid-ocean ridges
in deep ocean trenches
at the North and South pole
Identify the landform labeled A
mid-ocean ridge
deep ocean trench
sea floor spread
What is the process by which the ocean floor sinks beneath a deep ocean trench and back into the mantle?
continental drift
mid-ocean ridge
faults
subduction
What is Wegener's idea that continents are slowly moving over Earth's surface called?
divergence
faults
plates
continental drift
Most geologists think that the movement of Earth's plates is caused by
conduction
earthquakes
convection currents in the mantle
Earth's magnetic field
What are the places of Earth's crust that carry the continents and oceans?
sea floor spreading
continental drift
plates
faults
The geological theory that states that pieces of Earth's plates are in constant, slow motion, driven by convection currents is the theory of
subduction
plate tectonics
deep ocean trenches
sea floor spreading

When one tectonic plate sinks under another, this is called...
Convegent
Divergent
Subduction
Transform
Hotspots are volcanoes that form...
at convergent plate boundaries.
at divergent plate boundaries.
at transform plate boundaries.
in the middle of a tectonic plate.
Hotspots form because...
magma is pushed to the surface at a plate boundary.
a mantle plume weakens Earth's crust.
water is pushed up to Earth's surface
a mantle plume strengthens Earth's crust.
