1. Warm Up - Partner 1)How thick is the Crust, Mantle, and Core. 2)Based on the thickness of the layers, use a real life example to demonstrate the thickness of each layer. Example: The ladder is 40 ft long or roughly two stories tall.

2. 4.1 Layers of the Earth and Convection Objective: SWBAT identify the layers of the Earth and explain the various mechanisms that drive movement of lithospheric plates HW- Finish your layers foldable Agenda: Warm Up Objective Guided Notes Videos Earth foldable Exit Ticket

3. PUTTING IT ALL TOGETHER! WHY ARE WE LEARNING THIS? SWBAT identify the layers of the Earth by name, composition, thickness & density SWBAT explain the 3 different movements of tectonic plates & the mechanism causing such movements. 3

6. What did the world look like 1 million years ago?

7. Draw and Label the Following Diagram

8. Inner Core 1200 km = 745 miles  Miami to Charlotte

9. Outer Core 2250km = 1398 miles  Miami to NYC

10. Mantle 2900 km = 1802 miles  Miami to the tip of maine Composition: Magma/Rock State of Matter: Semi-Solid

11. Crust 11 CONTINENTAL Older Less Dense than Oceanic Crust Thicker OCEANIC Younger Mores dense than Continental Crust Covered by water Forms when plates separate

12. Crust 31.15 km = 19.36 miles Carowinds to UNCC

13. LITHOSPHERE – What is it? Combination of BOTH Crust & Upper Mantle 13

14. Critical Thinking Whiteboards INFER: What makes hot air balloons rise??

15. The entire surface of the earth is divided into tectonic plates that are constantly moving. How do they move??

16. Mantle Video

17. Convection The transfer of heat in the asthenosphere due to unequal heating from the core as magma heats up and rises, then cools down and sinks Moves the tectonic plates

18. Critical Thinking Whiteboard What is the connection between convection in the Earth’s Layers and Hot Air Balloons?

19. Mantle Video II

20. Density Which box is more dense?

21. Now, which is more dense?

22. What is density? D = m/v D = Density m = mass V = volume

23. White Board Activity Question: How does density relate to the layers of the Earth? Layers are divided by density. Question: How fast are the continents moving apart? Roughly 1.5 cm/year

24. What would your reaction be… When you are cold? When you are hot? Cold = fold arms, get close to someone, or rap in a blanket. Hot = less clothes, more spaced out, and don’t want to be as close to other people.

25. Same goes for particles How do particles change when they are cold and hot? Colder particles Hotter particles Cold objects: More dense Warm objects: Less Dense
