Tectonic Plate Vocabulary
Plate Tectonics
How and Why questions
World Examples Of The Three Boundaries
100
A large Slab of rock made up of mostly continental and oceanic lithosphere
What is a Tectonic plate?
100
a type of boundary that moves away from each other
What is a Divergent Boundary
100
The Divergent Plate Boundary is moving away from each other while the Transform boundary is sliding past each other, and the Convergent boundary is colliding.
How do the different plate boundaries behave?
100
The San Andreas Fault is on a plate that is sliding past another boundary
What is a World example of a Transform Boundary
200
the rigid outer part of the earth, consisting of the crust and upper mantle.
What is Lithosphere
200
A type of boundary that slides past each other
What is a Transform boundary
200
A divergent boundary consists of Mid Ocean Ridges, Rift Valleys, and Earthquakes. A convergent boundary has Subduction,Trenches, Volcanos, Volcanic Arcs, Volcanic Island Arcs, and Earthquakes. Last of all transform boundaries just have earthquakes
What features form along these boundaries?
200
Juan de Fuca
World example of convergent boundary
300
the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.
What is Asthenosphere
300
type of boundary that collides and creates trenches
What is convergent boundary
300
This feature is formed by subduction, when to plates converge the older denser plate is pushed under the lighter one deep into the mantle causing the sea floor to bend in a V shape or a trench
How does a trench form?
300
Andes Mountains
What is a real world example of a divergent boundary
400
thin part of the earth's crust that underlies the ocean basins
What is oceanic crust
400
Mountain system formed by plate tectonics
What is a Mid ocean ridge?
400
This feature is formed when the uplifting of the ocean floor occurs when convection currents rise from the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary
How does a mid ocean ridge form?
500
thick part of earths crust, its older than oceanic crust
What is continental crust
500
When to plates collide
What is a earthquake
500
This feature is formed on a divergent boundary and when it spreads it create a spreading apart of the surface
How does a Rift Valley form?
