Science Flashcards
Point where an earthquake ruptures and rocks break is the _____ or the _____.
focus or hypocenter
Origin point of the earthquake UNDERGROUND.
focus
Origin point of the earthquake above the focus, and is on the SURFACE.
epicenter
____ is one of the consequences of crustal plate movement.
Earthquake
Region that borders the pacific ocean and is frequented by volcanism-related geological activities.
Pacific Ring of Fire
Areas within a tectonic plate where magma is abundant.
Hot Spots
Places where earthquakes often occur along _______ or _____.
Limited zones or belts`
On the edge of the Pacific Plate lie a string of ______ volcanoes.
452
A mass of land that rises more than 600m the surrounding land.
Mountain
Formation process of mountains and mountain ranges.
Orogenesis
What plate boundary movement is called when the plates move like this:
→←
Convergent boundaries
What plate boundary movement is called when the plates move like this:
↑↓
Transform fault boundaries
What plate boundary movement is called when the plates move like this:
←→
Divergent boundaries
It refers to plates that separate and move apart in opposite directions forming new lithosphere.
Divergent boundaries
Formed when two plates move towards each other.
Convergent boundaries
Plates slide and slip past each other.
Transform fault boundaries
In convergent boundaries, what is formed if one plate MOVES UNDERNEATH the other?
Subduction zone
In convergent boundaries, what is formed if the two COLLIDE and COMPRESS?
Orogenic belt
A region of deformed rocks.
Orogenic belt
What is the speed of the movement of tectonic plates?
2.5 cm per year
4 Driving Forces of Plate Movement
Hint:
MC
SP
SP
RP
Mantle Convection
Slab Pull
Slab Push
Ridge Push
(Driving Forces of Plate Movement)
Definition: Convection currents drive the plates away form each other.
Mantle Convection
(Driving Forces of Plate Movement)
Definition: When a subducting plate sinks into the hot mantle, and the plates attached to the slab is pulled in as well.
Slab Pull
(Driving Forces of Plate Movement)
Definition: Occurs between 2 colliding plates, one is subducting underneath the other plate.
Slab Subduction
(Driving Forces of Plate Movement)
Definition: Happens when the lithosphere is pushed by the asthenosphere because of convection current of from the mantle.
Ridge Push
