1 Tuesday, December 15, 2015 A-Day Objective: YWBAT construct a model of seafloor spreading. Drill: What is seafloor spreading? At which type of tectonic boundary does it occur? Homework WOW quiz tomorrow

2 Answer Seafloor spreading is the process by which molten rock rises, cools, solidifies, and is pulled apart by tectonic plates. This process usually occurs along divergent boundaries.

3 Today’s Activities  Drill  Bill Nye – ‘Three truths on line’  Seafloor Spreading Model  Conclusion

4 Did you know…? The 2004 earthquake that occurred in the Indian Ocean near Sumatra, Indonesia triggered a series of tsunamis that killed over 200,000 people in 14 countries.

5 Closure If new oceanic lithosphere is created during seafloor spreading why isn’t the Earth growing?
