Interactions between plates occur along
|
|
|
their edges. There are three types of plate
|
|
|
margins:
|
|
|
(1) |
Divergent margins
|
|
|
form
mid-ocean ridges (over oceans) and
|
|
|
rift valleys (over lands)
|
|
|
(2) Convergent margins
|
|
|
form
deep-sea trenches (two oceanic plates
|
|
or ocean+continental plates) or high
|
|
|
mountains (such as Tibetan Plateau) (two
|
|
|
continental plates).
|
|
|
(3) |
Transform fault margins
|
|
|
form earthquake faults
