6. LT: I am learning how convection current works. The purpose is to identify how particle movement affects our lives. Today we will learn how convection forces move the lithosphere and how this movement affects the lithosphere. Warm-up: Entrance Ticket: How come the crust/lithoshpere is broken into plates and how do they cause changes on the Earth’s surface? CW: plate boundaries HW: None Language Goal! I can use the vocabulary words, diverging, converging and transforming plates, Pangaea and continental drift. Concept Goal!!! How does the convection current affect the lithosphere?

8. How come the lithosphere is broken into plates? Where does the energy come from to move the lithosphere? Do all plates move the same? Explain why What takes place on top of the lithosphere when plates move?

9. Remember the 3 forces you did to your milky way? 1) TENSION 2) COMPRESSION 3) SHEARING Where does the force come from to move the plates around?

10. Different Types of Boundaries http://pubs.usgs.gov/gip/dynamic/understanding.html

11. Plate Boundaries Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.

28. LT: To identify what the ring of fire and hot spots are. BTEOC: Students will be able to identify plate boundaries, hot spots, the ring of fire and analyze where to build a business or home. CW: hot spots, ring of fire and magnitude of earthquakes. HW:None

29. Review Plate Boundaries Plate Boundary Rap

30. Ring of Fire

31. The Pacific Ring of Fire, or just Ring of Fire for short, is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. The Ring of Fire has 452 volcanoes and is home to over 75% of the world's active and dormant volcanoes. [1] It is sometimes called the circum-Pacific belt or the circum-Pacific seismic belt earthquakesvolcanicPacific Oceanoceanic trenches volcanic arcsvolcanic belts dormant volcanoes [1]

32. About 90% [2] of the world's earthquakes and 81% [3] of the world's largest earthquakes occur along the Ring of Fire. Also, many of the world's volcanoes are located here. The next most seismic region (5–6% of earthquakes and 17% of the world's largest earthquakes) is the Alpide belt, which extends from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic. The Mid-Atlantic Ridge is the third most prominent earthquake belt. [2] [3]Alpide beltJavaSumatraHimalayasMediterraneanAtlanticMid-Atlantic Ridge
