Cov pov thawj ntawm Phaj Tectonics . Niaj hnub nimno continents tuav cov lus qhia rau lawv yav dhau los nyob deb. Cov pov thawj los ntawm fossils, glaciers, thiab complementary coastlines pab qhia li cas lub daim hlau ib zaug haum ua ke. Fossils qhia peb thaum twg thiab qhov twg cov nroj tsuag thiab tsiaj ib zaug muaj.
Kuj nug, dab tsi yog peb daim ntawv pov thawj rau phaj tectonics?
- Av qeeg.
- Continental drift.
- Hiav txwv nthuav dav.
- Teb chaws.
- Volcanism.
- Disastrophism.
- Lithosphere.
- Phaj.
Ib tug kuj yuav nug, dab tsi pov thawj txhawb txoj kev xav ntawm continental drift? Cov pov thawj rau continental drift Wegener paub tias cov nroj tsuag fossil thiab tsiaj xws li mesosaurs, cov tsiaj reptiles dej tshiab pom tsuas yog South America thiab Africa thaum lub sijhawm Permian, tuaj yeem pom muaj ntau yam. teb chaws . Nws kuj tau sib tw pob zeb ntawm ob sab ntawm Dej Hiav Txwv Atlantic zoo li cov duab dhos ua si.
Tsis tas li ntawd, dab tsi yog lub phaj tectonic txoj kev xav thiab sau cov pov thawj uas txhawb nqa nws?
Muab ob yam ntawm pov thawj uas txhawb nqa tus kev xav ntawm phaj tectonics . LUS TEB YUAV TSUM TAU: Cov duab ntawm cov teb chaws sib haum ua ke zoo li kev sib tw. Qhov sib txuam coastlines qhia qhov twg cov teb chaws tawg sib nrug. Cov pob zeb zoo tib yam uas tsim ntau dua 200 lab xyoo dhau los tau pom nyob rau ntau lub tebchaws.
Leej twg ua pov thawj phaj tectonic txoj kev xav?
Hauv xyoo 1912 tus kws ntsuas huab cua Alfred Wegener piav txog qhov nws hu ua continental drift, ib lub tswv yim uas ua rau tsib caug xyoo tom qab nyob rau niaj hnub no. txoj kev xav ntawm phaj tectonics .. Wegener nthuav nws kev xav nyob rau hauv nws 1915 phau ntawv Keeb Kwm ntawm Continents thiab Oceans.

Dab tsi yog cov pov thawj rau txoj kev xav ntawm endosymbiosis?
Cov pov thawj qhia tias cov chloroplast organelles kuj yog ib zaug cov kab mob dawb nyob. Qhov kev tshwm sim endosymbiotic uas tsim mitochondria yuav tsum tau tshwm sim thaum ntxov hauv keeb kwm ntawm eukaryotes, vim tias txhua tus eukaryotes muaj lawv
Koj ua pov thawj li cas cov kab yog sib npaug hauv cov ntawv pov thawj?
Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, sib npaug, ces cov kab sib npaug. Qhov thib ob yog yog tias qhov sib txawv sab hauv lub kaum sab xis, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv cov kab sib npaug, sib npaug, ces cov kab sib npaug
Dab tsi pov thawj siv cov duab ntawm lub dav hlau sib koom ua pov thawj cov khoom geometric?
Cov ntaub ntawv pov thawj uas siv cov duab ntawm lub dav hlau sib koom ua pov thawj geometric zog yog hu ua trigonometric
Dab tsi yog cov pov thawj ntawm continental drift txoj kev xav?
Kev nthuav dav ntawm Permo-Carboniferous glacial sediments nyob rau hauv South America, Africa, Madagascar, Arabia, Is Nrias teb, Antarctica thiab Australia yog ib qho ntawm cov pov thawj tseem ceeb rau txoj kev xav ntawm continental drift
