Plate Tectonics/Continents
The supercontinent that existed 250 million years ago.
What is Pangea?
The boundary between two plates moving together.
What is a convergent boundary?
The boundary between two plates moving apart.
What is a divergent boundary?
The boundary between two plates moving past each other.
What is a transform boundary?
This is the transfer of energy inside the mantle.
What are convection currents?
German scientist that proposed all continents were once part of a supercontinent.
Who is Alfred Wegener?
Mountain ranges are formed what type of boundary.
What are continental to continental convergent boundaries?
This is formed when divergent plates underneath the ocean move apart.
What is a mid-ocean ridge?
This is an active earthquake area due to a transform boundary.
What is a fault?
This is the innermost layer of the earth.
What is the inner core?
This hypothesis that suggests that continents are in constant motion.
What is the theory of Continental Drift?
This happens when a continental and oceanic plate converge.
What is subduction?
The process by which new ocean crust forms along a mid-ocean ridge.
What is sea-floor spreading?
These events can occur at transform boundaries.
What are earthquakes and faults?
The layer of molten iron and nickel that surrounds the inner core.
What is the outer core?
The Ring of Fire generally has these landforms in common.
What are volcanoes, rift valleys, and deep sea trenches?
This is formed at a subduction zone.
What is a trench?
These natural events could occur at a divergent boundary.

What are sea-floor spreading, earthquakes, and mid-ocean ridges?
The San Andreas Fault is caused by this type of boundary.
What is a continental to continental transform boundary?
This is the rigid layer consisting of the crust and uppermost part of the mantle.
What is the lithosphere?
These geological features not associated with boundaries but with plate movement formed Hawaiian Islands and the Bahamas.
(Hawaii, Phillipines, Bahamas)
What are hot spot volcanoes?
Caused by the Indian and Eurasian plates colliding.
(Convergent Boundary)
What are the Himalayan Mountains?
The North American Plate and the Eurasian Plate have formed this landform under the ocean.
What is the Mid-Atlantic Ridge?
This is where most transform boundaries are found.
Where is under the ocean?
The soft layer of the mantle on which the pieces of lithosphere slowly float.
What is the asthenosphere.
