Cov East African Rift system yog ib qho piv txwv ntawm qhov twg tam sim no tshwm sim . Cov East African Rift Valley stretches tshaj 3,000km los ntawm Gulf of Aden nyob rau sab qaum teb mus rau Zimbabwe nyob rau sab qab teb, splitting lub Neeg African phaj ua ob qhov tsis sib xws: cov phaj Somali thiab Nubian.
Ib yam li ntawd, tib neeg nug, dab tsi tshwm sim hauv East African Rift Zone?
Cov kev sib cais , nqaim cheeb tsam , yog ib qho kev txhim kho divergent tectonic phaj ciam teb qhov twg Neeg African Phaj yog nyob rau hauv tus txheej txheem ntawm kev faib ua ob daim hlau tectonic, hu ua Somali Phaj thiab Nubian Phaj, ntawm tus nqi ntawm 6–7 mm (0.24–0.28 in) txhua xyoo.
Tsis tas li ntawd, muaj dab tsi tshwm sim hauv Great Rift Valley? Geologists paub tias cov Rift Valley tau tsim los ntawm kev ua phem subterranean rog uas rhuav tshem lub ntiaj teb crust. Cov rog no ua rau cov chunks loj ntawm cov pob zeb hauv av los ntawm cov kab uas tsis sib thooj thiab ua rau cov pob zeb molten hauv volcanic eruptions.
Tsis tas li ntawd, dab tsi yog qhov ua rau lub rift kwj hauv Africa?
Sab Hnub Tuaj African Rift yog ib tug zoo tectonic nta ntawm Teb chaws Africa , ua rau los ntawm kev tawg ntawm lub ntiaj teb crust. Qhov no astronaut yees duab ntawm Eastern ceg ntawm lub Rift (ze Kenya tus ciam teb yav qab teb) qhia txog cov qauv geological classical txuam nrog tectonic rift hav.
Lub East African Rift cuam tshuam li cas rau phaj tectonics?
Cov East African Rift Valley (EAR) yog ib qho kev sib txawv phaj ciam teb hauv Sab hnub tuaj Teb chaws Africa. Nubian thiab Somalian daim hlau kuj cais tawm ntawm cov neeg Arab phaj nyob rau sab qaum teb, yog li tsim 'Y' zoo li tus kev rifting qhov system. Cov no daim hlau Kev sib tshuam hauv thaj av Afar ntawm Ethiopia ntawm qhov hu ua 'triple junction'.

Qhov twg tshwm sim thawj lub teeb nyob ntawm qhov tshwm sim lossis lub teeb ywj pheej?
Lub Teeb-Dependent thiab Lub Teeb-Independent Reactions. Cov tshuaj tiv thaiv lub teeb, lossis cov tshuaj tiv thaiv lub teeb-dependent, yog thawj zaug. Peb hu lawv ob leeg thiab ob lub npe. Nyob rau hauv lub teeb-dependent tshwm sim ntawm photosynthesis, lub zog ntawm lub teeb propels lub electrons los ntawm ib tug photosystem mus rau lub high-zog lub xeev
Lub East African Rift cuam tshuam li cas rau phaj tectonics?
Lub East African Rift Valley (EAR) yog ib qho kev sib txawv ntawm thaj tsam ntawm East Africa. Lub Nubian thiab Somalian daim hlau tseem sib cais los ntawm Arabian phaj nyob rau sab qaum teb, yog li tsim kom muaj 'Y' zoo li tus rifting system. Cov phiajcim no hla hauv thaj av Afar ntawm Ethiopia ntawm qhov hu ua 'triple junction'
Dab tsi tshwm sim ntawm Theodor Engelmann qhov kev sim nto moo qhia rau nws uas wavelength S yog tus tsav tsheb zoo tshaj plaws ntawm photosynthesis?
Cov kab mob sib sau ua ke ntau tshaj plaws nyob ze ntawm ib feem ntawm cov alga uas tau nthuav tawm cov xim liab thiab xiav wavelengths. Engelmann qhov kev sim ua kom pom tias lub teeb liab thiab xiav yog lub zog zoo tshaj plaws rau photosynthesis
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Yuav ua li cas koj pom qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug?
Txhawm rau xam qhov tshwm sim ntawm qhov tshwm sim tshwm sim tsawg kawg ib zaug, nws yuav yog qhov sib ntxiv ntawm qhov xwm txheej tsis tshwm sim. Qhov no txhais tau hais tias qhov tshwm sim ntawm qhov tshwm sim yeej tsis tshwm sim thiab qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug yuav sib npaug, lossis 100% txoj hauv kev
