1st Quarter, Lesson 5: Plate Boundaries Flashcards
What is Plate Boundary?
A boundary between 2 or more plates
What are the different types of Plate Boundaries?
Divergent
Convergent
Transform
What is Divergent?
These are boundaries moving away from one another. The magma goes up, causing two landforms to separate.
How are rocks pulled apart in Divergent?
Tension Stress
This causes Seafloor spreading.
Divergent
What can Divergent cause?
Rift Valleys, Ridges, Fissure Volcanoes
Two Tectonic Plates moving towards one another.
Convergent
Two plates are collided due to ______
Compression Stress
What are the 3 types of Convergent?
Oceanic-Continental
Oceanic-Oceanic
Continental-Continental
What is Oceanic-Continental?
It overrides the oceanic plates (mountain ranges)
This depends on the age of the crust.
Oceanic-Oceanic
Continental-Continental
This is where two continents are faced head on and create the highest mountain ranges.
What is the transform fault boundary?
It is where it moves in opposite directions. Shear Stress. Causes Earthquakes.
This is where the rock is pushed in two opposite directions but doesn’t destroy crust.
Transform
