Hydrothermal vents yog feem ntau pom nyob ze qhov chaw volcanically active, thaj chaw uas tectonic daim hlau yog tsiv sib nrug ntawm cov chaw sib kis, dej hiav txwv bass, thiab hotspots. Hydrothermal tso nyiaj yog pob zeb thiab mineral ore deposits tsim los ntawm qhov kev txiav txim ntawm hydrothermal vents.
Yog li ntawd, hydrothermal vents pom li cas?
Hydrothermal vents daim ntawv nyob rau hauv volcanic thaj chaw uas subseafloor chambers ntawm nce magma tsim undersea roob ranges hu ua mid-ocean ridges. Cov dej hiav txwv txias nkag mus rau hauv cov kab nrib pleb hauv hiav txwv thiab tuaj yeem ua kom sov txog li 750 ° F (400 ° C) los ntawm kev cuam tshuam nrog cov pob zeb magma-rhuab subsurface.
Kuj Paub, yog vim li cas tej zaum hydrothermal vents yuav nyuaj nrhiav tau? Cov nrhiav tshiab hydrothermal vents yog nyuaj vim cov cheeb tsam tsuas yog ob peb kaum mus rau ib puas meters loj yuav tsum pom nyob rau hauv lub hiav txwv loj. Rau qhov kev tshawb fawb no, cov kws tshawb fawb hauv hiav txwv feem ntau ntiav cov sensors qis dua los ntawm lub nkoj ntawm cov hlau hlau. Tom qab ib ncig ntawm 20 teev lawv rov qab mus rau lub nkoj.
Ntawm no, dab tsi nyob ze hydrothermal vents?
Tshawb nrhiav tsuas yog xyoo 1977, hydrothermal vents nyob hauv tsev rau kaum ob ntawm yav dhau los tsis paub hom . Loj liab-tipped raj worms, ghostly ntses, coj txawv txawv cws nrog ob lub qhov muag ntawm lawv nraub qaum thiab lwm yam tshwj xeeb hom vam meej nyob rau hauv cov dej hiav txwv tob heev ecosystems pom nyob ze undersea volcanic chains.
Puas yog hydrothermal vents txaus ntshai?
Hydrothermal vents tuaj yeem muaj cov kua qaub thiab cov tshuaj uas feem ntau yuav yog phom sij rau tsiaj. Lub hauv paus rau lub neej nyob ib ncig ntawm lub qhov cua yog ib hom kab mob uas siv cov tshuaj no. Cov kab mob tuaj yeem ntes lub zog los ntawm cov txheej txheem tshuaj lom neeg uas mus ncig ntawm cov no qhov cua.

Magnetic fields tso lub plotting compass ze ntawm cov hlau nplaum ntawm ib daim ntawv. kos cov kev taw qhia ntawm lub tshuab raj lub ntsiab lus. txav lub plotting compass mus rau ntau txoj haujlwm sib nqus hauv qhov chaw sib nqus, kos lub koob taw qhia txhua zaus. koom nrog cov ntsiab lus los qhia cov kab teb
Yuav ua li cas koj nrhiav tau qhov sib npaug ntawm ib kab uas muab ib tug point thiab ib tug parallel kab?
Qhov sib npaug ntawm kab hauv daim ntawv nqes hav-intercept yog y = 2x + 5. Qhov nqes hav ntawm parallelline yog tib yam: m = 2. Yog li, qhov sib npaug ntawm kab sib npaug yog y = 2x + a. Txhawm rau nrhiav ib qho, peb siv qhov tseeb tias kab yuav tsum dhau los ntawm qhov muab: 5 = (2) ⋅ (− 3) + a
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Henri Becquerel nrhiav tau dab tsi uas ua rau nws tau txais 1903 Nobel nqi zog Nws nrhiav tau dab tsi txog lub caij uranium?
Teb: Henri Becquerel tau txais ib nrab ntawm qhov khoom plig rau nws qhov kev tshawb pom ntawm cov hluav taws xob tsis zoo. Teb: Marie Curie tau kawm txog cov hluav taws xob ntawm tag nrho cov tebchaw uas muaj cov xov tooj cua paub, suav nrog uranium thiab thorium, uas nws tom qab pom kuj tseem muaj xov tooj cua
Yuav ua li cas ib tug geologist yuav qhia tau hais tias ib tug quav yog ib tug syncline thiab anti-line?
Geologic Structures (Part 5) Anticlines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips deb ntawm lub crest. Synclines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips mus rau lub trough ntawm lub quav. Koj tuaj yeem nco qab qhov sib txawv los ntawm kev ceeb toom tias anticlines tsim "A" zoo, thiab synclines tsim hauv qab ntawm "S."
