plate boundaries

Draw this
diagram in
your notes.

Lithosphere

•Made of

crust and
top part of
mantel

Asthenosphere

•Upper

mantle…

•Liquidy-solid

Oceanic vs
Continental crust

Copie the following
on the diagram
given.

Oceanic Crust

• Thinner
• More Dense
• Younger rock formation

Continental Crust

• Thicker
• Less Dense
• Older rock formations

Plate boundaries.

Where tectonic plates meet.

Types of boundaries

• Convergent

– Continental to continental

– Continental to oceanic

– Oceanic to oceanic

• Divergent

• Transform.

Convergent (Continental
to continental)

• They collide

– Come together

• Creates

– Mountains/ Earthquakes/ subduction

zones

Convergent (Continental
to Oceanic)

• Collide

– Oceanic moves under continental

• Volcanoes, trenches, earthquakes,

subduction zones

Convergent (Oceanic to
Oceanic)

• collide
• Island Arcs, trenches,

earthquakes,

Divergent

• Plates move away from each other
• Mid-ocean ridges, rift valleys,

earthquakes

Transform

• Two plates scrape/ slide past each

other

• Earthquakes
