Contiental Drift
What plate boundary happens when the plates move away from each other
What is a divergent boundary?
This is the underlaying (weak) soft liquid flowing layer which allows the earth's plates to move. Asthenosphere or Lithosphere
What is the Asthenosphere?
This type of plate boundary involves two plates moving apart from one another.
What is a divergent boundary?
These features are produced on earth when two continents collide and force land upward
What are mountains or volcanoes
These features form as new crust rises to the surface from volcanoes-also called the ring of fire
What are mid-ocean ridges?
This is the rigid upper layer of the earth which includes the earth's crust and upper most mantle.
Lithosphere or Asthenosphere
What is the lithosphere?
This type of plate boundary involves two plates moving toward each other.
What is a convergent boundary?
The name of the magma that spews out of the volcanoes crater and onto land
lava
When a force pulls down on another object
gravity
This is the name of the Tectonic Plate that we are standing on
North American Plate
This type of plate boundary involves one plate sliding past another plate.
What is a transform boundary?
These natural disasters occur when a sudden movement and violent shaking occurs along transform boundaries.
What are earthquakes?
These are the two types of evidence that were initially used to support the Theory of Continental Drift.
What are continents fitting together like puzzle pieces, fossil evidence, coal in Antarctica, volcanoes or mid Ocean Ridge?
What is the theory of the movement of large slabs of land
Plate tectonics
This is the average distance the earth's plates move per year.
What is 10 cm
This is the term for one plate being forced underneath another plate.
What is Subduction?
What is the name of the reptile that supposedly would have to swim 5,000 miles
What is Messosaurus
The liquid inside the inner core of the volcano is called what as it begins to bubble
magma
These are the two types of crust found on earth based on their densities and thicknesses? (Hint: Think land and water)
What is continental crust (less dense, but thicker) and oceanic crust (more dense, but thinner)?
This is the term for the fracture or crack in the earth's surface created when one plate suddenly slides past another plate.
What is a fault?
These two features form in the ocean when one oceanic plate is forced below another oceanic plate (Subduction)- One Big place in the Pacific Ocean
What are trenches and volcanic islands?
