Continental Drift
What is the theory that the continents where moving?
100
Sea Floor Spreading
What discovery led to the introduction of plate tectonics?
100
Fault
What is a break in the Earth's crust called caused by stress?
100
Metamorphic Rock
What is the type of rock that changes form due to heat and pressure
200
convection
How is heat transferred through Earth's interior?
200
Pagaea
What was Alfred Wegener's super continent called?
200
the old rock pushed away from the ridge as new rock is created
What happens to the old rock in sea floor spreading?
200
Seismic Waves
What type of energy is released during an Earthquake?
200
Igneous Rock
What is the type of rock that is made from cooled molten rock?
300
same- upper mantle different - lithosphere is brittle rock, asthenosphere is molten rock
How are the lithosphere and asthenosphere the same? different?
300
Climate, fossils, landforms
What are the three evidences that Wegner used to support his theory?
300
a slow movement of the lithospheric plates ontop of the asthenosphere.
What is the definition of plate tectonics?
300
Epicenter - location on Earth's crust Focus- point in Earth's interior where rock breaks
What is the epicenter and the focus?
300
Sedimentary Rock
What type of rock is made from eroded pieces of Earth compacted together?
400
Seismic Waves
What do scientists use to study Earth's interior?
400
Harry Hess
How made the idea of continental drift come alive again thirty years after Wegner's death?
400
Subduction
What is is called when the oceanic crust goes underneath the continental crust?
400
Primary Waves, Secondary Waves, Surface waves
What are the three types of seismic waves in the order or arrival?
400
Rock Cycle
What is the series of processes that make, recycle, and destroy rock?
500
Crust (Oceanic and Continental Crust), Upper Mantle (Lithosphere and Asthenosphere), Lower Mantle, Upper Core, Inner Core
What are the layers and sub-layers of Earth's Interior?
500
Volcano
What is a weak spot in Earth's crust where molten material rises to the surface?
500
Convergent (comes together), Divergent (pulls away), Transform (slips past)
What are the three types of plate boundaries?
500
compression, tension, and shearing
What are the three types of deformation (stress)?
