Theory that states Earth's crust and upper mantle are broken into sections, which move around on a special layer of the mantle
|
Plate Tectonics
|
|
|
Area where an oceanic plate goes down into the mantle
|
subduction zone
|
|
|
Plate boundary that occurs when two plates slide past one another
|
Transform Boundary
|
|
|
Place where two plates move together
|
Convergent boundary
|

|
|
The youngest rocks in the ocean floor are located at mid-ocean ______.
|
ridges
|
|
|
The _____ are forming where the Indo-Australian plate collides into the Eurasian plate.
|
Himalayas
|
|
|
What happens to warmer material in a convection current?
|
warmer material rises
|
|
|
How was the Andes Mountain Range formed?
|
The Andes were formed at the convergent boundary of an oceanic plate and a continetal plate.
|
|
|
How were the islands of Japan formed?
|
two oceanic plates collided
|
|
|
What causes new material to form at a mid-ocean ridge on the ocean floor?
|
Hot, less dense material below Earth's crust is forced upward at the mid-ocean ridges. Then it turns and flows sideways, carrying the seafllor away from the ridge in both directions.
|
|
|
Most divergent boundaries are located ________
|
where two oceanic plates are dividing
|
|
|
New oceanic crust is created at divergent boundaries at a rate of about ______.
|
5 cm per year
|
|
|
When two plates converge, which plate can slide into the mantle?
|
only the oceanic crust can slide into the mantle.
|
|
|
This is formed when a continental and continental plate converge.
|
mountain range
|
|
|
This is formed when an oceanic and oceanic plate converge.
|
island arc
|
|
|
This is formed when a continental and oceanic plate converge.
|
volcanic arc
|
|
|
The location where new sea floor is being formed_____
|
oceanic ridges
|
|
|
Based on the plate tectonics theory, the age of the oceanic crust should _____
|
get older as we move away from the oceanic ridges
|
|
|
New sea floor is continually being created along _____
|
divergent boundaries
|
|
|
Old sea floor is being destroyed continually along ____
