PLATE BOUNDARIES Flashcards
Most active Volcanoes around the world are located ________ . It is where the subduction or sinking process occur
near the plate boundaries.
________ - A series of mountains or hills ranged in a line and connected by high ground. (Example: Sierra Madre)
Mountain Range
_________ a series of mountain ranges with similarity in structure (Example: Appalachians Mt. in N. America)
Mountain Belt -
A ________ is formed due to the oozing up of materials along divergent plate boundary.
mid ocean ridge
Mountain ranges and oceanic ridges are both located ______
near the plate boundary
Most earthquake epicenters are located near the plate boundary where most crustal movements are felt. They are highly concentrated in a region called as the _________ where Philippines is also situated.
“pacific ring of fire”
- hotter part will rise while the colder part sinks (uneven heating)
- An area within the fluid where warm material is rising in the center and cold materials is sinking at the edges
If the material is less dense, it will rise. If the material is denser it will sink
Convection Cell
________ move due to the convection of the mantle. (the lithospheric plate is not a one big plate, there are plate boundaries that exist)
Lithospheric plates
A ________ is where two or more plates meet.
plate boundary
is formed when two plates move away from each other.
DIVERGENT PLATE BOUNDARY
When two plates move away from each
other, it can form:
❏ New ocean floor
❏ mid -oceanic ridges
❏ Rift valleys
occurs when two plates move toward each other and form either a subduction zone or an orogenic belt.
CONVERGENT PLATE BOUNDARY
if one plate moves underneath the other.
SUBDUCTION ZONE
If the two plates simply collide or compress. A region of deformed rocks.
OROGENIC BELT
three kinds of convergence:
❖Oceanic-oceanic collision
❖Oceanic-continental collision
❖Continental-continental collision
