What are the three types of plate boundaries and the sub types of convergent plate boundaries?

Question

Thank you who ever can answer this difficult ?

Answer 1

convergent: two plates running into on another

divergent: pulling apart

and Convection: sliping past one another

and subduction is a convergence when one plate goes beneath another.. oftern oceanic sliping under a continental plate

Answer 2

Divergent boundaries -- where new crust is generated as the plates pull away from each other.
a. continental rift zone (like east African rift)
b. ocean spreading center (like mid-Atlantic ridge)
Convergent boundaries -- where crust is destroyed as one plate dives under another.
a. oceanic-oceanic convergence (island arc systems-like Japan margin)
b. oceanic-continental convergence (like South American margin, or Pacific North West of U.S.)
Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other (like San Andreas fault system in California).

Answer 3

Oceanic-oceanic:collide; one slides underneath the other, creating deep sea trenches.(Mariana Trench) Oceanic-continental: collide; same as above, deep sea trenches, but creates mountains at the continental side.(West coast of South Amerca, Andes) Continental-continental: collide, same as above and creates mountain ranges.(Himalayan Mountains, Indian and Asian plates)
