Introduction to Science and Geology
100
This is another name for a divergent boundary.
What is a mid-ocean ridge?
100
Most convergent boundaries are this type.
What are subduction zones?
100
The best studied transform boundary on Earth.
What is the San Andreas Fault?
100
Plates are composed of this.
What is lithosphere?
100
A tentative idea that explains observed phenomena.
What is hypothesis?
200
The theory that explains the magnetic reversals as seen as mirror images across the divergent boundaries.
What is paleomagnetism?
200
Most convergent boundaries are located around this major area of the Earth's surface.
What is the Pacific Ocean or the Ring of Fire?
200
This type of stress is associated with transform motion.
What is shear stress?
200
The largest earthquakes occur here.
What are subduction zones?
200
A well tested and accepted explanation that answers a posed question.
What is theory?
300
This is created at divergent boundaries.
What is new lithosphere?
300
The chain of volcanoes that occurs above an ocean-ocean convergent margin.
What is volcanic island arc?
300
These are called conservative boundaries because of this.
What is lithosphere is neither created nor destroyed at these boundaries?
300
The rate at which plates move on the Earth's surface.
What is 1-10 cm/yr?
300
This line of thought can be summarized by the statement "the present is the key to the past."
What is uniformitarianism?
400
This type of stress is associated with divergent boundaries.
What is tensional stress?
400
The only current example of a continent-continent collision zone.
What is the Himalayas?
400
A transform boundary where a stream is offset to the right on the opposite side of the fault is called this.
What is right lateral motion?
400
The rise of warm material and the sinking of cool material describes this idea.
What is convection?
400
4.6 billion years
What is the commonly accepted age of the Earth?
500
This type of faulting is associated with divergent boundaries.
What is normal faulting?
500
The deepest earthquakes occur at convergent boundaries because of this.
What is lithosphere is found deepest at this type of plate boundary?
500
What do transform boundaries transform?
What is motion between two other plate boundaries?
500
This explains why the Earth is neither shrinking or expanding.
What is equal rates of creation and destruction of lithosphere?
500
The idea that Earth's landscape has been formed by periodic rapid violent events.
What is catastrophism?
