100
The theory that the continents started as one supercontinent
What is continental drift
100
The theory that proposes that earth's outer shell slowly, but continuously moves
What is plate tectonics
100
The consequences of divergent boundaries
What is oceanic ridges, seafloor spreading, and continental rifts
100
The permanent magnetization acquired by rock that can be used to determine the location of magnetic poles
What is paleomagnetism
100
This occurs in the mantle and is the basic driving force for plate movement
What is convection
200
The man that proposed continental drift
What is Alfred Wegener
200
The number of major plates
What is seven
200
The consequences of convergent boundaries (3)
What is oceanic-continental, oceanic-oceanic, and continental-continental
200
Deep-focus earthquakes create ocean trenches
What is earthquake patterns
200
Downward arm of convective flow in the mantle
What is slab-pull
300
The name of the supercontinent
What is Pangea
300
The number of minor plates
What is six
300
When the plates grind past each other without destroying the lithosphere
What is transform fault boundaries
300
Scientists have found seafloor sediment that helps to confirm the plate tectonic theory.
What is ocean drilling
300
Causes oceanic lithosphere to slide down the sides of oceanic ridges
What is ridge-push
400
Continental drift
What is a theory that was proposed in 1915
400
The earth's outer shell or mantle
What is lithosphere
400
When the plates split and matter comes upward
What is divergent boundaries
400
Volcanoes create islands
What is hot spots
400
The unequal distribution of heat within in the Earth causes the thermal convection in the mantle that drives plate motion
What is mantle convection
500
The four pieces of evidences Wegener had to support his proposal
What is continental puzzle, matching fossils, rocks types & structures, and ancient climates
500
The three types of boundaries
What is divergent, convergent, and transform fault
500
When the plates come together and push matter downward
What is convergent boundaries
500
Evidence for plate tectonics (4)
What is paleomagnetism, earthquake patterns, ocean drilling, and hot spots
500
Causes of plate motion (3)
What is slab-pull, ridge-push, and mantle convection
