Plate boundaries Flashcards
Chain of volcanoes that develop parallel to the trench
Volcanic island arc
a break or a fracture in the earth’s crust
Fault
Consequences: Volcanoes, Trench
Oceanic will subduct
Examples:
Chile Trench and Andes Mountain
Oceanic - Continental
force exerted in a certain area
Stress
Destructive: melting or destroying of the lithosphere
Convergent
due to underwater disturbance
tsunami
Types of Convergent Plate Boundary
Oceanic-Continental
Ocean-ocean
Continental-continental
What process is called when 2 tectonic plates collide towards each other, one plate eventually slides beneath the other.
Subduction
The himalayan mountain range of India was formed at the _____
Convergent boundary
Constructive: Creation of a new atmosphere due to the rising and cooling of hot mantle
Consequence: Mid-Ocean ridges, Rift valleys
Divergent
The East African Rift is an example of a _____
Rift Valley
Convergent
stress: ?
fault: ?
Stress: Compression, Fault: Reverse
One plate is oceanic, there are large volcanoes found in lines that outline the subduction zone. Earthquakes also happen in these zones.
Oceanic-continental
When two plates collide, they have a density lower than the mantle which prevent subduction (submersion of plates under each other) so they create mountains.
Continental-continental
Consequence : Earthquakes and Active fault lines
Shallow Earthquakes = less than 70km
Deep Earthquakes = more than 70km
Conservative: Nothing is created nor destroyed
Horizontal
Transform Fault
One of the plates (oceanic crust and Lithospheric mantle) is pushed, or subducted, under the other that mixes with the overlying mantle, and the addition of water to the hot mantle lowers the crust’s melting point that leads to the formation of magma.
Ocean-ocean
Seafloor spreading is located at
Divergent plate boundary
Transform Fault/ Transform Boundary
stress: ?
fault: ?
Stress: Shear, Fault: Strike-slip
Consequences : Tsunamis, Trenches
Older plate will be the one to subduct
Examples:
Mariana Trench
oceanic-oceanic
Types of plate boundaries
Transform
Convergent
Divergent
Consequences: Mountain, Mountain Ranges
No Subduction Occurs
Crust Buckles upward
Example:
Himalayas
Continental- Continental
depression in the seafloor produced by the subduction process
Trench
An example of transform fault boundary
San Andreas Fault
Divergent
stress: ?
fault: ?
Stress: Tension, Fault: Normal
