DO NOW 1. Which layer of the Earth is the most dense? Explain. 2. What layer of the Earth Is divided into an upper, cooler, more rigid rock and a lower, hotter, softer rock?

THE EARTH IS MADE OF LAYERS Copy Notebook BACK OF PAGE 17 Crust Mantle Outer Core Inner Core

LAYERS OF THE EARTH Lithosphere -Together the crust and upper mantle are called the lithosphere and they extend about 80 km deep. Asthenosphere -The asthenosphere is flexible and can be pushed and deformed like silly putty in response to the warmth of the Earth. These rocks actually flow, moving in response to the stresses placed upon them by the churning motions of the deep interior of the Earth. (convection)

BOOK CHECK OUT Changing Earth Books 1. Take a book, fill out the information on the sheet as it gets passed around the room 2. The book number is on the yellow tag. 3.

DO NOW SWBAT describe evidence of Alfred Wegener’s Theory of Continental Drift 1. Alfred Wegener, a German scientist proposed that all of the continents on Earth were once joined together in a massive supercontinent called Pangaea. Observe the map above. What evidence, or inferences could you make to support Alfred Wegener’s claim?

CLASS CLOSE READ Highlight Annotate what you think as you go through it 1. What are some examples of scientific changes that you have noticed in the past few years? 2. Can new scientific ideas come from old observations or evidence? Why or why not? Scientific changes also involve developing new theories to explain observations or reinterpret old evidence. The facts may not change, but the explanation does.

EVIDENCE JIGSAW This is the evidence that Alfred Wegener gathered, as well as a couple of new pieces of evidence that was later added to theory in the mid 1900’s to further support continental drift. Individually, close read the section of article your group is assigned 1. Highlight important details and information about the section you are assigned. 2. Make annotations about things that come to mind when reading

DO NOW (TUES) SWBAT describe the difference between divergent, convergent, and transform plate boundaries Enter Silently Grab Materials Begin Do Now Alfred Wegener’s hypothesis of continental drift was rejected because he didn’t have evidence to explain how the continents drifted apart from each other. 1. Describe how do tectonic plates move as if you were telling a first grader.

HOW DO THE PLATES MOVE? The lithosphere is made up of these giant slabs of rock called tectonic plates that “float” on top of the asthenosphere. Convection is the transfer of energy by the movement of fluids Convection occurs in the Asthenosphere Heated rock rises, then cools and starts to sink https: //youtu. be/ryr. XAGY 1 dm. E 1. If convection is a way for heat to transfer, where is the heat coming from to make the asthenosphere rise and fall?

PLATE BOUNDARIES

TYPES OF LITHOSPHERIC PLATE BOUNDARIES Boundary Type Divergent – plates move away (separate) Results Picture Rift Valleys (Africa) Ocean Ridges – Sea floor spreading (Mid-Atlantic Ridge) New Crust Convergent – plates Volcanoes (Ring of Fire) move together Builds mountains (Himalayas) (collide) Plates shrink Creates trenches Subduction - one plate is pushed into the mantle where it melts.

DO NOW (TUES- CONVERGENT BOUNDARIES) Make a prediction: Fossils deposited in a deep sea 400 million years ago are now found on top of Mount Everest, the highest mountain in the world. Why are marine fossils at the top of the tallest mountain in the world?

(subduction= TRENCH) "The Summit of Mt. Everest is Marine Limestone" The great nature writer John Mc. Phee wrote about Mount Everest in his book Basin and Range: "When the climbers in 1953 planted their flags on the highest mountain, they set them in snow over the skeletons of creatures that had lived in the warm clear ocean that India, moving north, blanked out. Possibly as much as twenty thousand feet below the seafloor, the skeletal remains had turned into rock. This one fact is a perfect example for the movements of the surface of the Earth.

WHAT TYPE OF BOUNDARY CREATED THE EARTHQUAKE? The 2011 Japan Tsunami Was Caused By Largest Fault Slip Ever Recorded Experts calculate the fault—or the boundary between two tectonic plates—in the Japan trench slipped by as much as 164 feet (50 meters). Other similarly large magnitude earthquakes, including the 9. 1 Sumatra event in 2004, resulted in a 66 -to-82 foot (20 -to-25 meter) slip in the fault. "We've never seen 50 -meter [slips], " said Kelin Wang, a geophysicist with the Geological Survey of Canada in British Columbia.
