100
Who was first to propose the theory of continental drift?
Who is Alfred Wegener
100
The place where two plates move apart.
What is a divergent boundary?
100
The place where two continental plates come together or collide.
What is a convergent boundary?
100
The plate boundary where two plates slide against each other in opposing direction.
What is a transform boundary?
100
When two plates collide and the more dense plate dives underneath the less dense plate.
What is subduction?
200
Explains the formation, movement, and subduction of Earth's plates.
What is the Theory of Plate Tectonics?
200
This is a geographic effect of a divergent boundary on land.
What is a rift valley or canyon?
200
The geographic effect of convergent boundaries
What are mountain ranges and mountains?
200
A geologic effect of transform boundaries.
What are earthquakes?
200
This plate subducts when an oceanic plate collides with a continental plate
What is an oceanic plate?
300
Oceanic and continental plates are found in this layer of the earth.
What is the lithosphere?
300
Divergent boundaries do occur on land, but most occur here.
What is the mid-ocean ridge?
300
The reason that two plates carrying continental crust don't subduct.
What is density?
300
The reason earthquakes occur at transform boundaries.
What is the release of extreme pressure?
300
A geographic feature created by oceanic - continental subduction.
What is on-shore volcanic mountains and deep ocean trenches.
400
The crust and lithosphere float on the hot, soliquid material of this layer.
What is the asthenosphere?
400
The process by which new crust forms along the mid-ocean ridge.
What is sea-floor spreading?
400
Another geographic or geologic effect of two continental plates colliding
What are uplifted plateaus and rock deformation?
400
Subduction will occur when two plates carrying oceanic crust meet here.
Where is a trench?
500
The three pieces of evidence that Wegener used to support his theory of continental drift.
What is landform evidence, climate evidence, and fossil evidence?
500
An example of a geographic effect of divergent boundaries, found in East Africa.
What is The Great Rift Valley?
500
The geographic feature that began to form when the continental plate carrying India slammed into Asia.
What are the Himalayas?
500
A major contributing factor to the seismic activity in California.
What is the San Andreas Fault
500
Another name for boundaries where subduction occurs
