Rifting
• The process by which Earth’s crust breaks apart.• New, smaller continents may
form as a result.
Terranes• A TERRANE is a piece of lithosphere that has
a unique geological history. –Contains rocks and fossils that differ from
nearby terranes.–Major faults at the boundary of a terrane.–Magnetic properties of a terrane do no
match nearby terranes.
Terranes• When a Terrane on a subducting plate
converges with a plate of continental crust the terrane is scraped off the subducting plate and is added to the continental plate.
• Some terranes form mountains, some just add more surface area.
• This process is called ACCRETION.
The Supercontinent Cycle• SUPERCONTINENT= when all of the landmasses form one
large continent (scientists believe there have been at least 5 different supercontinents since the first crust formed on Earth).
• SUPERCONTINENT CYCLE = the process by which supercontinents form and break apart over time.
• PANGAEA= the supercontinent that formed 300 million years ago and began breaking up 250 million years ago which led to our modern continents.
• PANTHALASSA= the single, large ocean that covered the Earth’s surface during the time of PANGAEA.
