What is plate motion
What is the plate boundary called when plates come together
Convergent Boundaries
Who came up with the Continental drift theory
Alfred Wegner
When two continental plates come together what land formation form
Mountains
What is one piece of evidence that supports plate Theory
Fossil Record
What is earths layer called that includes the upper mantle and crust
Lithosphere
What is the plate boundary called when the plates seperate
Divergent Boundary
Who was the scientist that supported Alfred Wegners Theory
Harry Hess
When two ocean plates come together what land formation forms
Possible volcanic activity
What is another piece of evidence that supports plate Theory
Geographic columns
What is the lower mantle called
asthenosphere
What is the plate boundary called when the plates slide.
Transform Boundary
What theory Supported Alfred Wegners theory and who came up with it
Seafloor Spreading, Harry Hess
What is the other land formation occurs when two ocean plates comes together
Trenches
What is another piece of evidence that supports plate Theory,
-What can be used to measure plate movement
GPS Tracking
What is the outer core made of
nickle and iron
Describe what happens when an ocean plate meets a continental plate
The ocean plate goes under the continental plate due to the ocean plate being more dense.
Describe The full concept of Plate Theory
The plates were once all together called Pangea, they then began to separate become Eurasia and Gondwanaland, then further separated to how they are today
What land formation occurs at subduction zones, where do these zones occur
Volcanoes
What is another piece of evidence that supports plate Theory,
-What can be used to measure plate movement
GIS Tracking
What is the inner core made of?
Is it a solid or Liquid
Solid, Iron
How do plates move, draw the CORRECT model, and describe the motion
TBD
Describe the concept of seafloor spreading, what are these spots called.
The convection currents crack open the crust allowing lava to come magma, causing new rock to form, pushing the plates apart. These spots are called Hot Spots.
What is the land formation called, where you can see the separation of the plates
a Fault line
Describe How geographic columns support the theory of plate movements.
Continents that were once together, will have geographic (rock ) layers that pair up with one another.
the Layers tell us the history of the earths rocky layer.
The further down the layer the older it is.
Describe their differences and layers they can travel through and why.
P waves: can travel through the crust, mantle, outer core and inner core
S wave: mantle and crust
