Continental Drift

QuestionAnswer
What is the type of tectonic plate boundary involving a collision? convergent boundary
What is the type of tectonic plate boundary that sometimes has a subduction zone? convergent boundary
The San Andreas fualt is an example of what type of boundary? transform boundary
What is the type of fault where the hanging wall moves down? normal fualt
Mid-ocean ridges are found at what type of boundaries? divergent
What do fossils on seperate continents indicate? the continents were once connected
What causes the movement of tectonic plates? convection current
Which layer is divided into tectonic plates? lithosphere
What type/s of crust make up the North American plate? continental and oceanic
What is the name of the ancient supercontinent that contained all of the landmasses? Pangaea
What is the name of the ancient sea thta surrounded the ancient landmass? Pathalassa
What are the names of the two continents that the supercontinent broke into? Luarasia and Gondwang
What is the name for the process of hot material rising nad cool material sinking? convection current
Two tectonic plates slide past one another horizontally at what boundary? transform
Two tectonic plates move away from one another at what boundary? divergent
What type of fualt is it where the haging wall moves up? reverse
Deep ocean trenches are formed at what type of boundary? convergent
What process creates new oceanic lithosphere? sea spreading
What are underwater mountainchains called? mid-ocean ridges
What is the theory that Earth's lithosphere moves around called? plate tectonics
What is the surface along which rock breaks and moves called? fualt
Identify the three types of fualts. normal, reverse, strike-slip
What is an ocean trench? underwater canyons where the oceanic crust bends downwards. in a pricess taking millions of years, parts of the ocean floor sinks back into the mantle at deep-ocean trenches
What is a subduction zone? the process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle again
What is sea-floor spreading? it adds more crust to the ocean floor while older peices of rick move outward from either side of the ridge.
What is a mid-ocean ridge? they form long chains of mountains that rise up from the ocean floor
What is a convergent boundary? plates that come together or converge
What is a divergent boundary? plates that move apart or diverge from each other
What is a transform boundary? plates that slip past each other
