Plate Boundarires Flashcards
What are tectonic plate boundaries?
Tectonic plate boundaries are the edges where two tectonic plates meet.
Name the three main types of tectonic plate boundaries.
Divergent, convergent, and transform boundaries.
True or False: Divergent boundaries occur where plates move away from each other.
True
Fill in the blank: Convergent boundaries are characterized by plates moving __________.
toward each other
Which type of boundary is associated with the creation of mountain ranges?
Convergent boundaries
Identify the type of plate boundary that causes earthquakes due to sliding past one another.
Transform boundaries
What is the San Andreas Fault an example of?
A transform boundary
True or False: Subduction occurs at divergent boundaries.
False
What is created when an oceanic plate subducts beneath a continental plate?
A volcanic arc
Multiple choice: Which of the following is NOT a type of tectonic plate boundary? A) Divergent B) Convergent C) Static D) Transform
C) Static
Fill in the blank: The Himalayas were formed by the collision of the __________ and __________ plates.
Indian, Eurasian
What type of boundary is associated with the formation of new oceanic crust?
Divergent boundaries
True or False: Transform boundaries can create new land.
False
What is the primary result of tectonic activity at convergent boundaries?
Earthquakes and volcanic activity
What is the term for the process where one tectonic plate moves under another?
Subduction
Multiple choice: Which type of boundary is the Mid-Atlantic Ridge? A) Convergent B) Divergent C) Transform D) None of the above
B) Divergent
Fill in the blank: At a __________ boundary, two plates slide past each other horizontally.
transform
What type of tectonic activity is most common at divergent boundaries?
Seafloor spreading
True or False: All tectonic plate boundaries are associated with volcanic activity.
False
What is the Ring of Fire?
A region of high seismic and volcanic activity surrounding the Pacific Ocean.
What occurs when two continental plates collide?
They create mountain ranges, as neither plate subducts.
Multiple choice: Which process is primarily responsible for the movement of tectonic plates? A) Erosion B) Convection C) Weathering D) Sedimentation
B) Convection
Fill in the blank: Oceanic plates are generally __________ than continental plates.
denser
What happens at a transform boundary?
Plates grind past each other, causing earthquakes.
True or False: Divergent boundaries can occur on land as well as under the ocean.
True
What is one potential hazard associated with transform boundaries?
Earthquakes
