2. Create a flashcard for each of the following terms (found on p.255 in your text book). • Rifting • Terrane • Supercontinent cycle • Pangaea • Panthalassa If you finish early, study your flashcards! Key Terms

3. The process by which Earth’s crust breaks apart. • New, smaller continents may form as a result. Rifting

4. 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

5. 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. Terranes

6. 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. The Supercontinent Cycle

7. What is a supercontinent? ________________________________________________________________________ • ___________ was the most recent supercontinent. Quick Check!!

8. As tectonic plates continue to move Earth’s geography will change dramatically. • East Africa will rift and separate from Africa, North and South America will collide with Africa, Los Angeles will be North of San Francisco! Geography of the Future
