- 14. What evidence isthere for these plate boundaries?
- 15. Where are thedeepest earthquakes?
- 16. Where would youexpect to see volcanoes?
Editor's Notes
- #11 ISANG TEORYA NA NAGPAPALIWANAG NA ANG MUNDO AY BINUBUO NG MALALAKING TIPAK NG LUPA ANG MALALAKING TIPAK NG LUPA NA ITO AY TINATAWAG NA LITHOSPHERIC PLATES. ITONG MGA LITHOSPHERIC PLATES NA ITO AY NASA TAAS NG MANTLE AT NAKADEPENDE SA PAGGALAW ANG MAGIGING RESULTA O EPEKTO NITO SA MUNDO.
- #12 SA PAG AARAL NG PLATE TECTONICS MERONG DALAWANG PRINCIPLE NA DAPAT LAGING TANDAAN PARA MAIPALIWANAG KUNG BAKIT GUMAGALAW ANG MGA LITHOSPHERIC PLATES PRINCIPLE 1 READ AND PRINCIPLE 2 IT IS BECAUSE OF READ. PWEDE NATIN ITONG IHAMBING SA KUMUKULONG SINAING OR ISANG BOILING POT OR SOPAS. SO WHAT HAVE YOU NOTICE SA SINAING?NA HABANG TUMATAAS ANG TEMPERATURA ANG TUBIG AY KUMUKULO. LETS COMPARE KUNG ANG MAGMA AY MASYADO NG MAINIT IT WOULD RATHER RISE UP ONCE IT REACHES THE TOP IT WOULD COOL OFF OR LALAMIG SYA AND THE IT WOULD BE PUSHED BACK DOWN. AND IF IT REACHES AGAIN AT A CERTAIN TEMPERATURE, TATAAS NA NAMAN ULIT AND YOU WILL NOTICE THAT SULIT2 LANG OR CYCLE. AND THIS CYCLE IS WHAT WE CALLED CONVECTION CURRENT.WSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
- #13 THE CONVECTION CURRENT IS THE REASON WHY LITHOSPHERIC PLATES MOVES.
- #14 ANO-ANO NGA BA ANG BUMUBUO SA LITHOSPHERIC PLATES SO ACTUALLY THERE 8 PRIMARY PLATES AND THE OTHERS ARE COMPOSED OF SECONDARY PLATES WHICH IS VERY SMALL SO THE DIFFERENT PLATES ARE THE EURASIA PLATE READ IN THE PICTURE SO THE OTHER PLATES HAS CONTINENTS ON IS UPPER PART AND THE OTHERS WAAY MAN SO MEANING THEY ARE AT THE BOTTOM OF THE OCEAN BUT ALL OF THESE MAY IT BE PRIMARY OR SECONDARY ALL OF THESE PLATES ARE MOVING AND THAT IS BECAUSE OF CONVECTION CURRENT. Ano ayhan ang bases nga amo da ya forms na.
- #15 The first bases for the boundaries of the tectonic plates is what you call a seismicity and the distribution of earthquakes. In other words amo ja ang mga lugar kung sa diin kaagi naglinog. And mga spots nga da ya mga lugar sa kalibutan nga nakaagi dun linog kag asta subong gakaranas gihapon ka linog.
- #16 So as you’ve noticed, if we based on the diagram, mas damo ang earthquakes sa mga plate boundaries kung sa diin gatabuaay ang mga lithospheric plates. And the deepest quakes happens at the subduction zones.
- #17 If lantawon ta sa map where there are earthquakes there are also volcanoes and most likely you can see volcanoes on the plate boundaries or if mag meet ang 2 lithospheric plates. So amo ja ang ginbasihan in order for the scientist to determine what are the different type of lithospheric plates, so we have seismicity kung sa diin gakatabo ang linog another is click
- #18 The location of the volcanoes
- #19 And the last one are the location of major mountain belts.
- #20 So you might be wondering kung gahulag gd man ang lupa insa nga indi the manotice? So actually it moves but it moves very slow so 1-10cm lang per year or kung gaano kadaacg magtubo ang aton mga kuko. It isn’t much but if you are going to multiply it by say a millions a years so definitely and distansya or movement would be very evident or kapansin2. so ang slowest ay sa African plate, and the fastest is on the samoa tungga microplates
- #22 THE CRUST AND LITHOSPHERIC PLATES ARE DIFFERENT KABILANG KA DADI ANG CRUST AT UPPER MANTLE. WHEN WE TALK ABOUT THE CRUST IT IS THE OUTER LAYER OF THE EARTH CHEMICALLY DISTINCT FROM THE UNDERLYING MANTLE LAYER. SO THE CRUST IS ONLY A PART OF THE LITHOSPHERIC PLATES WHEN WE TALK ABOUT THE ATMOSPHERIC PLATES, IT IS RIGID AND BRITTLE CONTAINS GRASS AND UPPER MANTLE 100KILOMETERS THICK AND IT HAS SOME FRACTURES WHERE THE EARQUAKES ORIGINATES.
- #23 Asthenosphere is not a liquid actually it is visco-elastic solid meaning indi sya pareho ka liquid nga dacg magflow so it is more-likely ginmelt nga plastic mahinay ang ana paghulag.
- #25 There are 3 types of plate boundaries. Nakadepende sa paggalaw in between this lithospheric plates kung ano ang epekto nito sa earth’s crust kung san magkalinog, magkatsunamis, pagkabuo ka volcanoes or pagbuo ka mga bukid. Now lets try to differentiate the 3 types of boundaries kg kung ano ya matabo sa amo ja nga boundaries
- #26 The first type is the divergent boundaries, places with this type of boundiries as earthquakes nga babaw lang kag mahina. Amo ja ya mga lugar kung sa diin my gakabuo nga bag o nga lupa or my bag o nga crust as it falls apart. Virgin boundaries ay ang pagbulag ka mga lithospheric plates next
- #27 There are 3 classes the first 1 is the ocean/ocean convergence. There are 3 main types in this type of boundaries ara ang oceanic to oceanic plate convergence next is ang pagbungguanay ni oceanic
