Nto moo piv txwv ntawm sib xyaw cones yog Mayon Volcano , Philippines, Mount Fuji hauv Nyiv, thiab Mount Rainier, Washington, Tebchaws Asmeskas A . Qee qhov sib xyaw volcanoes ua tau ob rau peb txhiab meters nyob rau hauv qhov siab tshaj lawv lub hauv paus. Feem ntau volcanoes sib xyaw tshwm sim hauv chains thiab raug cais los ntawm ob peb kaum kilometers.
Tsis tas li ntawd, dab tsi yog qhov sib xyaw volcanoes eruptions zoo li?
A volcano sib xyaw yog tsim ntau pua txhiab xyoo los ntawm ntau yam tawg . Cov tawg txhim tsa lub volcano sib xyaw , txheej rau txheej kom txog rau thaum nws towers ntau txhiab meters siab. Qee cov khaubncaws sab nraud povtseg yuav tsim los ntawm lava, thaum lwm tus yuav yog tshauv, pob zeb thiab pyroclastic ntws.
Tom qab ntawd, lo lus nug yog, dab tsi yog qhov sib xyaw volcanoes ua los ntawm? Cov tawg roob hluav taws kuj spew tawm eruptions ntawm me me pob zeb thiab tshauv, uas tau tso rau ntawm ob sab ntawm lub roob hluav taws . Yog li ntawd, peb pom qhov ntawd volcanoes sib xyaw yog muaj li ntawm alternating txheej ntawm hardened lava, roob hluav taws tshauv thiab pob zeb tawg, yog vim li cas lawv hu ua ' sib xyaw.
Qhov thib ob, qhov twg yog qhov sib xyaw volcanoes pom?
Composite volcanoes feem ntau pom nyob rau ntawm qhov chaw puas tsuaj. Piv txwv ntawm cov volcanoes sib xyaw suav nrog Mount Fuji ( Nyiv ), Mount St Helens (USA) thiab Mount Pinatubo (Philippines).
Qhov twg feem ntau cov volcanoes sib xyaw ua ke?
Lub Nplhaib ntawm Hluav Taws Feem ntau cov volcanoes sib xyaw ua ke nyob rau hauv subduction aav uas ciam teb ntawm ib tug tectonic phaj mus nyob rau hauv lwm lub phaj. Tectonic daim hlau sawv cev rau cov khoom ntawm lub ntiaj teb lub pob zeb uas kov thiab txav mus, ua rau av qeeg thiab roob hluav taws formations raws ciam teb no.

Yuav ua li cas yog ib tug piv txwv ntawm ib tug electron cab kuj?
Raws li cov electrons raug xa mus los ntawm ib lub tshuab nqa hluav taws xob mus rau lwm qhov, lawv lub zog theem qis, thiab lub zog tawm. Cytochromes thiab quinones (xws li coenzyme Q) yog qee qhov piv txwv ntawm cov khoom siv hluav taws xob
Yuav ua li cas yog ib qho piv txwv ntawm kiag li xoom?
Tus xoom xoom yog sib npaug rau 0 ° K, − 459.67 ° F, lossis − 273.15 ° C. Thaum qhov kub thiab txias nce mus txog xoom, cov yam ntxwv ntawm lub cev ntawm qee yam khoom hloov pauv loj heev. Piv txwv li, qee yam khoom hloov pauv ntawm cov hluav taws xob hluav taws xob mus rau cov khoom siv hluav taws xob, thaum lwm tus hloov los ntawm cov hluav taws xob mus rau cov hluav taws xob
Yam ua piv txwv piv txwv li cas?
Ib khub xaj yog ib khub ntawm tus lej hauv ib qho kev txiav txim. Piv txwv li, (1, 2) thiab (- 4, 12) raug txiav ua khub. Qhov kev txiav txim ntawm ob tus lej tseem ceeb: (1, 2) tsis sib npaug rau (2, 1) -- (1, 2) ≠ (2, 1)
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Yuav ua li cas yog ib tug piv txwv ntawm ib tug rational naj npawb uas tsis yog ib tug tag nrho?
Tus lej "rational" yog qhov piv ntawm ob tus lej. Piv txwv li, cov hauv qab no yog cov lej rational, thiab tsis muaj leej twg yog tus lej: 1 / 2. 2 / 3
