Plate Tectonics And Earthquakes Flashcards
Liquid layer of earth core
Outer core
Outermost layer of earth
Lithosphere
Fault cause of tension
Normal
Fault cause compression
Reverse
Reverse fault where does the hanging wall move relative to the footwall?
Upward
Normal fault, hang wall move to footwall
Downward
Force to sharp mts
Tension
Area where tectonic plates meet
Boundary
When tectonic plates collide
Convergent
Plates separate
Divergent
Plates slide past
Transform
NOT evidence for continental drift
Oceanic plate theory
1st continent
Pangea
Where does sea floor spreading take place
Mid ocean ridges
Measure movement of tectonic plates
Global Positioning System
Hardens to form new rock at mid ocean ridges
Magma
Measure density of earth layers
Seismograph
Evidence for continental drift
Fossils
Evidence for sea floor spreading
Magnetic reversal
