Continental Crust –
•About 200 km thick
• lighter than oceanic crust
•much made from sedimentary rock.
Oceanic Crust –
•About 100 km thick
•heavy made from basalt (igneous rock.)
Notice how the
Oceanic Crust is
pushed below
the Continental
Crusts
Divergent Plate Boundary – Area where plates are moving
apart.
Examples• Mid-Atlantic Ridge
• African Rift Valley
Convergent Plate Boundary – Area where plates are moving
together.
Examples A)
Collision Boundary – Area where 2 continental plates collide creating
mountains like the Himalayas in Asia.
B)
Subduction Zone – Area where an oceanic plate is forced under a continental
plate; this is where volcanoes are formed.
Transverse Plate Boundary – Area where two plates are
sliding past each other.
Examples –
• San Andreas Fault in California.
This is a Divergent plate boundary!
