Convergent plate boundaries --> <--
100
List one type of land form that occurs at a divergent plate boundary.
Mid-ocean ridge
100
What is the outermost layer of the Earth? *DAILY DOUBLE*
Crust
100
What is continental drift?
The idea that the continents used to fit together in one landmass that drifted apart over time.
100
Would evidence from seismic waves be direct or indirect evidence?
indirect
200
What type of plate boundary is associated with shearing force? *DAILY DOUBLE*
transform boundary
200
List one type of land-form that occurs at a transform plate boundary.
Fault
200
What is the thickest layer of the Earth?
Mantle
200
Who is the scientist who first proposed continental drift?
Alfred Wegener
200
Would evidence from rock samples be direct or indirect evidence? Why?
direct because you can observe them directly.
300
What type of plate boundary is associated with tensional force?
Divergent Boundary
300
List three types of land forms that occur at a convergent plate boundary.
Mountains, volcanoes, trench/subduction zone
300
Which layer of the Earth has convection currents that drive plate tectonics?
Mantle/ asentosphere
300
What was Alfred Wegener's missing piece of evidence for continental drift? *DAILY DOUBLE*
He did not have a way that the continents moved.
300
Where is the youngest oceanic crust located?
at a mid ocean-ridge
400
What type of force is associated with a transform boundary?
Shearing force
400
When two continental plates come together, what type of land form does this create?
mountains
400
Which layer is made of liquid Iron and Nickel
Outer Core
400
Why are signs of climate change evidence that the continents moved?
As the continent moved to a different spot on Earth, the climate changed based on how close the the equator and poles it was.
400
Where is the oldest oceanic crust located? *DAILY DOUBLE*
subduction zone
500
What type of force is associated with a divergent boundary?
Tensional force
500
When two oceanic plates come together, what type of land form does this create? *DAILY DOUBLE*
trench/subduction zone
500
Which layer is under the most pressure?
Inner core
500
What are 4 pieces of evidence of continental drift?
same fossils between continents, climate change, same geological features (ex-mountains) between continents, shape of continents look like fitting puzzle pieces.
500
What are three pieces of evidence that support seafloor spreading?
Magma coming through the surface, magnetic stripes, drilled rock samples
