Monday, December 07, 2015 A-Day Objective: YWBAT depict and explain the break-up of Pangaea. Drill: Explain how sea floor spreading provides a way for continents to move. Homework Study words of the week

Answer In sea-floor spreading tectonic plates are pushed apart from each other through the creation of new lithosphere.

Did you know…? In the 1950’s scientists broadcast sound waves toward the sea floor and measured how long it took the waves to return. The echoes revealed the existence of oceanic valleys and mountains.

Today’s Activities  Drill  BrainPop  Read Chapter 7, Section3  Define WOW  Conclusion
