What causes the movement of the plates?
The Earth's convection current
Which direction do the arrows point in convergent boundaries?
Towards each other
What direction do the arrows point
away from each other
What direction do the arrows point in a transform boundary?
parallel to each other
What was the name of the supercontinent?
Pangea
How many plate boundaries types exist?
3
What feature is formed with continental to continental convergent boundaries?
Folded mountains.
What feature is created when two continental plates move away from each other?
Rift Valley
What feature is created with a transform boundary?
A fault line
Glacier Scaring was a key piece of evidence that Alfred Wegener proposed for the movement of the plates. True or False
True
Which type of plate boundaries move against each other creating friction?
Transform Boundaries
What type of features are formed with a continental to oceanic plate boundaries? Name at least one.
Oceanic Trenches and Volcanoes
What features is created when a divergent oceanic and oceanic plate boundary split? Name at least one
Sea floor spreading, ridge, and volcanoes
What natural disaster is a result of this boundary?
Earthquakes
How many major plates exist?
7 major plates
Which movement results in folded mountains?
convergent boundaries
What is a famous mountain chain formed by convergent to convergent plate boundaries where Mt. Everest is found?
Himalayan Mountains
Which is the name of a famous ridge that is found in the ocean?
Mid Atlantic Ridge
What is a famous fault line found in California?
San Andreas Fault
Was Alfred Wegeners theory accepted? Explain
No, because he could not explain how the plates moved.
What causes deep ocean trenches?
convergent boundaries with subduction.
What do you call one plate going beneath the other?
subduction
Divergent boundaries can cause volcanic activity. True or false.
True
The ring of fire is a result of Transform boundaries. True or False.
FALSE. It is a result of subduction in convergent boundaries!
