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

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.

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

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.

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