Ua li no, puas yog kev ua volcanic ua rau Me Me Ice Age?
Cov kws tshawb fawb qhia tias cov Me ntsis Ice Age tau tshwm sim los ntawm qhov txawv txav, 50-xyoo rov ntawm plaub loj volcanic eruptions . Qhov no ua rau muaj kev nthuav dav ntawm hiav txwv dej khov thiab ib qho cuam tshuam tsis muaj zog ntawm Atlantic tam sim no ua rau lub sij hawm txias kom pheej mus centuries.
Tsis tas li ntawd, Toba puas ua rau lub hnub nyoog dej khov? Qhov no yuav tshwm sim thaum nyob ib ncig ntawm 70-75,000 xyoo dhau los Toba caldera hauv Indonesia tau dhau los ntawm qeb 8 lossis "mega-colossal" tawg ntawm Volcanic Explosivity Index. Qhov no tej zaum yuav txo tau qhov nruab nrab ntawm lub ntiaj teb no kub los ntawm 3 mus rau 3.5 degrees Celsius rau ob peb xyoos thiab tej zaum yuav ua rau ib tug tshwm sim. dej khov muaj hnub nyoog.
Yog li ntawd, dab tsi tshwm sim rau Me Me Ice Age?
Cov Me ntsis Ice Age yog ua rau los ntawm kev ua kom txias ntawm cov volcanic loj heev tawg, thiab txhawb nqa los ntawm kev hloov pauv hauv Arctic dej khov npog, cov kws tshawb fawb xaus. Ib pab neeg tshawb fawb thoob ntiaj teb tau kawm txog cov nroj tsuag thaum ub los ntawm Iceland thiab Canada, thiab cov sediments nqa los ntawm glaciers.
Yuav ua li cas volcanoes cuam tshuam rau glaciers?
Thaum twg dej khov nthuav, tag nrho cov dej khov ua rau lub siab loj heev ntawm lub ntiaj teb saum npoo. “Nws ua tau cuam tshuam magma ntws thiab qhov khoob thiab qhov khoob hauv lub ntiaj teb uas magma ntws mus rau saum npoo thiab ntau npaum li cas magma lub crust tuaj yeem tuav tau, Swindles hais. Thaum twg dej khov rov qab, lub siab nqa thiab roob hluav taws kev ua si surges.

Lub organelle twg yog lub luag haujlwm rau lub zog tshuaj uas xav tau rau lub cell ua haujlwm?
Mitochondria Function Mitochondria feem ntau hu ua "powerhouses" lossis "zog factories" ntawm lub xovtooj vim tias lawv yog lub luag haujlwm rau kev ua adenosine triphosphate (ATP), lub xovtooj ntawm lub zog nqa lub cev
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Lub co2 hluav taws tua hluav taws puas ua haujlwm ntawm hluav taws kub oxidizer?
Lub tshuab tua hluav taws xob carbon dioxide tsis yog qhov kev xaiv zoo rau kev tua hluav taws oxidizer vim nws ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev tsis suav nrog cov pa oxygen, thiab cov pa oxygen atmospheric tsis xav tau rau hluav taws kub oxidizer. Cov tshuaj tua hluav taws qhuav qhuav kuj tseem yuav siv tsis tau rau feem ntau
Lub luag haujlwm ntawm lub tshuab hluav taws xob yog dab tsi?
Lub luag haujlwm ntawm lub tshuab hluav taws xob xa hluav taws xob yog thauj hluav taws xob los ntawm cov khoom siv mus rau cov neeg siv kawg. Switchyards thiab substations yog ib qho tseem ceeb ntawm cov kab ke no. Ib lub chaw hloov hluav taws xob, lossis hloov chaw, yog lub chaw nres tsheb tsis muaj qhov hloov pauv uas ua haujlwm tsuas yog nyob rau theem ib qho hluav taws xob
