Between the Mantle and Core at 2900km
Where are the boundaries the same for the major chemical compositions of the Earth and the major physical states of the Earth?
Major physical states (because these are the layers that are actually involved in the tectonic movement.)
Which is better to explain tectonic movement, the major chemical compositions of the earth or the major physical states?
Crust, Moho, Mantel, Core
List the layers of the major chemical compositions of the earth from the surface to the middle.
Lithosphere, Asthenosphere, Deep Mantle, Outer Core, Inner Core
List the layers of the major physical states of the earth from the surface to the middle.
Divergent, Convergent, Transform
List the three main types of plate boundaries.
a new sea floor is formed
What happens when a divergent plate boundary is under water?
Ocean-Ocean, Ocean-Continent, Continent-Continent
Name the three sub-types of Convergent Plate Boundaries.
Convergent Boundary
At which of the three main boundary types would one find a "subduction zone"?
Compression
What type of stress would be expected at a Convergent Boundary?
Tension
What type of stress would be expected at a Divergent Boundary?
Shear
What type of stress would be expected at a Transform Boundary?
Mid-Atlantic Ridge
Where would you expect to find oceanic spreading ridge?
East African Plate
Where would you expect to find Continental Rift?
South Pacific
Where would you expect to find Ocean-Ocean Convergence?
Himalayas
Where would you expect to find Continent-Continent Convergence?
Western South American Plate
Where would you expect to find Oceanic-Continent Convergence?
San Andreas Fault
Where would you expect to find Transform Faulting?
The East Coast of North America
Where would you expect to find a Passive Margin?
Hawaii and Yellowstone National Park
Where would you expect to find magmatism that is not associated with a plate margin ("Hot Spot")?
subduction
At a plate boundary undergoing ocean-continent convergence the resulting process is....
