Plate tectonics
Sea-floor spreading
Continental Drift
Earth Layers
Boundaries
100
this is a block of lithosphere that consists of the crust and the rigid, outermost part of the mantle
What is a Tectonic Plate
100
underwater water mountains can be created due to this action
What is Uplift
100
name this large landmass that was once together, but then separated due to plate tectonics
What is Pangea
100
this is the thickest layer of the earth
What is the Mantle
100
this is the boundry formed by the collison of two lithospheric plates
What is Convergent Boundary
200
Sea floor spreading takes place at this ridges
What is mid-ocean ridges
200
this is the hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations
What is continental drift
200
this layer is mostly the crust and is located in the upper mantle
What is Lithosphere
200
this is the boundry between two tectonic plates that are moving away from eachother
What is Divergent Boundary
300
this is the bending of rock layers due to stress
What is Folding
300
this causes a plate to be forced upward, while the other plate is forced downward
What is Subduction
300
this is the thin and solid outermost layer of the Earth above the mantle
What is Crust
300
what is the boundry between tectonic plates that are sliding past each other horizontally
What is Transform Boundary
400
this is a break in a body of rock along which one block slides relative to another
What is Fault
400
This also can be created due to sea-floor spreading
What is under water volcanoes
400
This crust weighs less than the oceanic crust
What is Continental crust
400
this is the central part of the Earth below the mantle
What is the Core
400
this boundary can cause rift valleys
What is divergent boundary
500
this is the thinking of regions of the Earth's crust to lower elevations
What is Subsidence
500
this pushes upward out the cracks of the ocean as the sea-floor spreads apart
What is magma
500
Who created the Continental Drift Theory ?
Who is Alfred Wegener
500
this is the soft layer of the mantle on which the tectonic plates move
What is the Asthenosphere
500
**BONUS** Name some things that can be created from convergent boundaries
*Earthquakes *Volcanoes *Ocean Trenches *Subduction zone *Plate is consumed
