“ Dub Cov neeg haus luam yeeb "yog cov chimneys tsim los ntawm deposits ntawm hlau sulfide, uas yog dub . "Cov neeg haus luam yeeb dawb" yog cov chimneys tsim los ntawm cov pob zeb barium, calcium, thiab silicon, uas yog dawb. Underwater volcanoes ntawm kis ridges thiab convergent phaj ciam teb tsim kub springs hu ua hydrothermal vents.

Tib neeg kuj nug, dab tsi yog qhov tseem ceeb ntawm cov neeg haus luam yeeb dub rau biology?

Txawm hais tias lub neej yog qhov sib txawv ntawm qhov tob no, cov neeg haus luam yeeb dub yog qhov chaw ntawm tag nrho cov ecosystems. Hnub ci tsis muaj nyob, muaj ntau yam kab mob - xws li archaea thiab extremophiles - hloov cov cua sov, methane, thiab sulfur compounds muab los ntawm cov neeg haus luam yeeb dub mus rau hauv lub zog los ntawm cov txheej txheem hu ua chemosynthesis.

Kuj Paub, dab tsi hydrothermal vents muab? Hydrothermal vents txhawb nqa cov ecosystems tshwj xeeb thiab lawv cov zej zog ntawm cov kab mob hauv dej hiav txwv tob. Lawv pab tswj dej hiav txwv chemistry thiab ncig. Lawv kuj muab ib lub chaw kuaj mob uas cov kws tshawb fawb ua tau kawm txog kev hloov pauv rau dej hiav txwv thiab seb lub neej hauv ntiaj teb tuaj yeem pib li cas.

Kuj paub, tus neeg haus luam yeeb dub yog dab tsi?

A dub haus luam yeeb yog ib hom hydrothermal vent uas muaj nyob rau hauv dej hiav txwv pem teb. Nws yog ib qho tawg nyob rau hauv lub ntiaj teb nto los ntawm geothermally rhuab dej tawm los. Hydrothermal vents feem ntau pom nyob ze ntawm qhov chaw volcanically active, thaj chaw uas daim hlau tectonic txav sib nrug, dej hiav txwv bass, thiab hotspots.

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.
