Plate boundaries

Boundary

the border between two plate tectonics

transform plate boundary

produces faults

Alfred Wegener

made pangea

all earth in greek

what does pangea mean

continental drift

wegener called his hypothesis

CONVERGENT PLATE BOUNDARIES

called destructive plate

Oceanic-oceanic convergence

continental-Continental convergence

Continental -Oceanic convergence

3 types of convergent boundaries

Continental-Continental convergence

formation of large mountain ranges

Continental-Continental convergence

both are less dense neither are subducted

Continental-Continental convergence

indian plate & eurasian plate forms himalayas

Oceanic-oceanic convergence

forms deep ocean trench and island arc as magma rises from the subducted plate

Oceanic-oceanic convergence

pacific and philippine plate form mariana trench & mariana isalands

continental-oceanic convergence

denser plate subducts

continental-oceanic convergence

formation of volcanic mountain ranges and deep ocean trenches.

continental-oceanic convergence

nazca & south american = andes mountains & peru-chile trench

divergent plate boundary

called constructive plate

divergent plate boundary

tensional stresses

TRANSFORM PLATE BOUNDARIES

called a conservative boundary
