• 5. Rock clues (similar
• Oceanic and continental
• Oceanic and oceanic
• Continental and continental
will not have subduction.
• Divergent
• Convergent
• Transform
• Divergent- Mid-ocean ridges
• Convergent (without
subduction)- Mountains
• Convergent (with subduction)Volcanoes, volcanic islands,
and deep-sea trenches
• Transform- Earthquakes
• Laurasia
• Gondwanaland
• The continents drifted apart

• Hot rising
• Cool sinking
• Circular motion
• When a oceanic plate goes
under another oceanic plate
of a continental plate. It is a
type of convergent boundary.
• Younger crust is in the middle
• Older crust is on the outside
• Divergent Boundary
• The Atlantic Ocean is expanding
because 4 plates form a divergent
boundary in the middle of the ocean.
This is causing the seafloor to spread
apart. The Pacific Ocean is shrinking
because the Pacific Plate is surrounded
by convergent plate boundaries that
have subduction. Basically the Pacific
Ocean is being consumed.
