Convergent, Divergent, and Transform Boundaries
divergent boundaries
what creates new crust?
convergent boundaries
what destroys old crust?
mountains, volcanoes, and trenches
what forms at a convergent boundary?
rift vallies and mid ocean ridges
what forms at a divergent boundary?
deep ocean trench, volcanic arcs, subduction zones
what forms at a oceanic-continental collisions?
earthquakes/faults
what forms at a transform boundary?
mountains
what forms at continental-continental collisions?
lakes, volcanoes, and rift valleys
what forms at continental-continental divisions?
deep ocean trench, island arcs, and subduction zones
what forms at oceanic-oceanic collisions?
underwater volcanoes and mid- ocean ridges
what forms at oceanic-oceanic divisions?
earthquakes/faults
what forms when 2 plates twist/slide?
transform boundaries
what relocates crust?
convergent boundary
what type of boundary is shown in this picture?
divergent boundary
what type of boundary is shown in this picture?
transform boundary
what type of boundary is shown in this picture?
transform: Any of the following oceanic-oceanic oceanic-continental continental-continental
when 2 plates twist/ slide to form earthquakes
convergent boundary: oceanic-continental
when one oceanic plate collides with a continental plate creating trenches, volcanic island arcs, and subduction zones
subduction
when one plate sinks below another because it is more dense (heavy)
convergent boundary: continental-continental
when two continental plates collide creating mountains
divergent boundary: continental-continental
when two continental plates divide creating lakes, volcanoes, and rift valleys
convergent boundary: oceanic-oceanic
when two oceanic plates collide creating trenches and volcanic arcs
divergent boundary: oceanic-continental
when two oceanic plates divide creating underwater volcanoes and mid- ocean ridges
old, oceanic crust
which crust is most dense (heaviest)?
