Types Of Plate Boundaries Flashcards
What does convergent mean?
To move together
What is one example of a convergent plate?
The zone of subduction
The zone of subduction consists What type of earth quakes and volcanoes
Asymmetric
Do the earthquakes on the subduction zone get deeper further or closer from the plate boundary?(Why?)
Further
Is there a consistent floor age for the zone of subduction?
No
Is there a high or low elevation on the zone of subduction?Why?
High due to the mountains that form
Why are their deep oceanic trenches on the zone of subduction?
Due to the submerging plates
What is another type of convergent plate
Fold mountains
True/False fold mountains have a high elevation , have no earthquakes or volcanoes
False fold mountains have many shallow earthquakes, high elevation and no volcanoes
What does divergent mean?
To move apart
What is one example of a divergent plate
Spreading ridges/Mid Atlantic ridge
What type of earthquakes are located on spreading ridges?
Shallow symmetrical earthquakes
Are there a lot of volcanoes on spreading ridges?Why?
Yes
Why is there high elevation on spreading ridges
The volcanoes
How do the volcanoes on spreading ridges form?
Magma rising
What is the sea floor age of spreading ridges?
Symmetrical from youngest to oldest
What is another example of a divergent plate?
Fault block mountains/Sierra Nevada mountains
How do fault block mountains form?
One part of the plate is uplifted, while another part drops this results in mountains with one long slope and a sharp drop
What does transform mean?
To move alongside
What is one example of a transform plate?
The San Andreas fault
