What are the FOUR (4) WAYS our Earth’s PLATES MOVE? Plates can move apart… Plates in the middle ocean often move apart…DIVERGE Plates in the middle ocean often move apart…DIVERGE The middle of our ocean has the thinnest crust and THAT’S mostly where NEW Earth comes from! Hydrothermal vents build up new crust that slowly move away from each other PLATES move 4 ways! DIVERGING PLATES PLATES move 4 ways! DIVERGING PLATES MOVE AWAY form NEW CRUST usually from THIN MID-OCEAN (RIDGE). Geologists have mapped all of the Earth’s plates. Plates can collide together 2 ways! DIVERGING PLATES CONVERGING PLATES PLATES that MOVE AWAY form NEW CRUST usually from THIN MIDDLE OCEAN RIDGES. CONTINENTAL vs. CONTINENTAL CRUST MAGNETIC REVERSALS! CONVERGING PLATES OCEAN vs. CONTINENTAL CRUST When THICK continental crust CONVERGES with another THICK continental crust… Continental-continental collision=mountains PLATES move 4 ways! DIVERGING PLATES CONVERGING PLATES PLATES that MOVE AWAY form NEW CRUST usually FROM THE MIDDLE OCEAN RIDGES. MAGNETIC REVERSALS! CONTINENTAL to CONTINENTAL CRUSTS: MOUNTAINS!!!!!!! PLATES MOVE 4 WAYS: DIVERGING PLATES CONVERGING PLATES PLATES that MOVE AWAY form NEW CRUST usually FROM THE MIDDLE OCEAN RIDGES. CONTINENTAL vs. CONTINENTAL CRUST… MOUNTAINS form. MAGNETIC REVERSALS! CONVERGING PLATES OCEAN vs. CONTINENTAL CRUST PLATES move 4 ways! DIVERGING PLATES CONVERGING PLATES PLATES that MOVE AWAY form CONTINENTAL to CONTINENTAL NEW CRUST usually FROM (land to land)CRUSTS COLLIDE: THE MIDDLE OCEAN RIDGES. MOUNTAINS!!!!!!! MAGNETIC REVERSALS! CONVERGING PLATES OCEAN vs. CONTINENTAL CRUSTS OCEAN & CONTINENTAL PLATES COLLIDE The thin ocean plate gets pushed down by the thicker continental crust. A deep ocean trench forms as ocean crust is pushed down into the melt. OCEAN & CONTINENTAL PLATES COLLIDE The thin ocean plate gets pushed down by the thicker continental crust. A deep ocean trench forms as ocean crust is pushed down into the melt. PLATES move 4 ways… DIVERGING PLATES CONVERGING PLATES PLATES that MOVE AWAY form CONTINENTAL to CONTINENTAL NEW CRUST usually FROM (land to land)CRUSTS COLLIDE: THE MIDDLE OCEAN RIDGES. MOUNTAINS!!!!!!! MAGNETIC REVERSALS! CONVERGING PLATES OCEAN into CONTINENTAL CRUSTS—SUBDUCTION (the ocean crust melts below the thicker continental crust… VOLCANOES!!! PLATES move 4 ways… DIVERGING PLATES CONVERGING PLATES PLATES that MOVE AWAY form CONTINENTAL to CONTINENTAL NEW CRUST usually FROM (land to land)CRUSTS COLLIDE: THE MIDDLE OCEAN RIDGES. MOUNTAINS!!!!!!! MAGNETIC REVERSALS! CONVERGING PLATES OCEAN into CONTINENTAL CRUSTS—SUBDUCTION (the ocean crust melts below the thicker continental crust… VOLCANOES!!! The “ring of fire” is the Pacific Ocean plate pushing under other continental crusts JUST LOOK AT ALL THE DOTS! What happens with SUBDUCTION?

DIVERGING PLATES CONVERGING PLATES PLATES that MOVE AWAY form NEW CRUST usually FROM THE MIDDLE OCEAN RIDGES. CONTINENTAL to CONTINENTAL (land to land)CRUSTS COLLIDE: MOUNTAINS!!!!!!! MAGNETIC REVERSALS! TRANSFORM plates OCEAN into CONTINENTAL CRUSTS COLLIDE: SUBDUCTING PLATES VOLCANOES!!! Earth’s plates are moving… PLATES move 4 ways! DIVERGING PLATES CONVERGING PLATES PLATES that MOVE AWAY form NEW CRUST usually FROM THE MIDDLE OCEAN RIDGES. CONTINENTAL to CONTINENTAL (land to land)CRUSTS COLLIDE: MOUNTAINS!!!!!!! MAGNETIC REVERSALS! TRANSFORM plates OCEAN into CONTINENTAL CRUSTS COLLIDE: SCRAPE PAST each other SUBDUCTING PLATES VOLCANOES!!! Earth’s plates are transforming… PLATES move 4 ways! DIVERGING PLATES CONVERGING PLATES PLATES that MOVE AWAY form NEW CRUST usually FROM THE MIDDLE OCEAN RIDGES. CONTINENTAL to CONTINENTAL (land to land)CRUSTS COLLIDE: MOUNTAINS!!!!!!! MAGNETIC REVERSALS! TRANSFORM plates OCEAN into CONTINENTAL CRUSTS COLLIDE: SCRAPE PAST each other SUBDUCTING PLATES EARTHQUAKES! VOLCANOES!!! Using GPS we track which directions our tectonic plates are going. How many diverging plates do you see? When plates are moving away from each other, they are divergent plates. DIVERGENT plates undersea, as spreading ocean centers forming mid-ocean ridges. How many converging plates do you see? When plates are moving into each other, they are convergent plates. How many transform plates do you see? When plates rub past each other, they are transform plates. What kind of plate movement formed this? What kind of plate movement formed this? Subducting (continental over oceanic) plates! Sometimes a tectonic plate is too big heat evenly. So big plates have hot spots to keep the entire plate hot. Sometimes a tectonic plate is too big heat evenly. So big plates have hot spots to keep the entire plate hot. Sometimes a tectonic plate is too big heat evenly. So big plates have hot spots . . What plate movement made this happen? What plate movement made this happen? • TRANSFORM PLATE BOUNDARIES! More transforming plate disasters. When plates move, tsunamis happen. What kind of RARE plate movement is this? When plates move, tsunamis happen. What kind of RARE plate movement is this? Ocean to Ocean plate converging! the horizon and retreated water indicate a forthcoming Tsunami. This photograph shows the 2004 Tsunami in Thailand. Instead of seeking shelter, the people are amazed about the coming w Spray at the horizon and retreated water indicate a forthcoming Tsunami. This photograph shows the 2004 Tsunami in Thailand. Instead of seeking shelter, the people are amazed about the coming waves. The people have realised that something is wrong. But it is too late now. What plate movement causes tsunamis? A. B. C. D. Is it ocean to continent subduction? Is it continent into continent converging? Is it ocean into ocean subduction? Is it ocean crust from ocean crust diverging? What plate movement causes tsunamis? • usually ocean into ocean plate subduction! END!!!! Altogether, geologists, archaeologists and paleontologists have been able to retrace how our continents slowly developed and drifted all over our planet. http://www.youtube.com/watch?v=IbcVM3MdiWw&feature=related BEST with the future: http://www.youtube.com/watch?feature=fvwp&NR=1&v=uGcDed4x VD4 http://www.youtube.com/watch?v=GNmUd43pabg&feature=related Connected with life form evolution for later.
