Total questions: 37
Worksheet time: 23mins
Why did scientist reject Wegener's idea of continental drift?
it did not provide a force to cause plate motion
they thought it was a fairytale
his idea didn't account for gravity
Wegener's idea had nothing wrong with it
How were mid-ocean ridges discovered?
a satellite
submarine
surveys of the ocean floor done by a ship
divers
Why are magnetic patterns important evidence for plate tectonics?
the patterns show the waves' movement
it proves that new ocean floor moves away from the center of an ocean ridge
magnetic patterns do not support plate tectonics
What what the name of the supercontinent formed 250 million years ago?
Pangaea
Laurasia
Gondwanda
Neverland
The hypothesis that says Earth continents once made up an ancient supercontinent and have been slowly floating apart ever since is called ?
Plate Tectonics
Natural Selection
Continental Drift
Relativity

close to an ocean ridge
far away from an ocean ridge
ocean trenches
ocean rifts
During seafloor spreading, molten material rises up rom the mantle...
along the continents
deep ocean trenches
at the mid ocean ridges
at north and south poles
Which of the following is where one plate slides under another plate?
submarine
subduction zone
divergence zone
lower zone
Most volcanoes and earthquakes occur?
along tectonic plate boundaries
in the Arctic
along the coast
in the ocean
The Theory of _______ ________ states that the Earh's crust and upper mantle are broken into sections that are in constant, slow motion.
Seafloor Spreading
Continental Drift
Divergent Boundaries
Plate Tectonics
This type of plate boundary forms when two continents collide. It is responsible for the formation of the Himalayan Mountains and the Alps. Lots of earthquakes, but no volcanoes go with these very high mountains.
Convergent Boundary
Divergent Boundary
Rift Valley
Transform Boundary

Convergent
Divergent
Subduction
Transform
Transform
