Holmes theorized tias convection tam sim no txav mus los ntawm lub mantle tib txoj kev uas cua sov circulates los ntawm ib chav tsev, thiab radically reshape lub ntiaj teb nto nyob rau hauv tus txheej txheem. Holmes kuj to taub qhov tseem ceeb ntawm convection raws li ib tug mechanism rau poob ntawm tshav kub los ntawm lub ntiaj teb no thiab ntawm txias nws nyob rau hauv sib sib zog nqus.

Yog li ntawd, leej twg nrhiav tau convection tam sim no?

Arthur Holmes (1890-1965) yog ib tus kws tshawb fawb Askiv uas tau ua ob qho tseem ceeb rau kev txhim kho cov tswv yim geological: kev siv cov xov tooj cua isotopes rau kev yos hav zoov thiab cov lus tawm tswv yim tias cov dej ntws hauv lub mantle ua lub luag haujlwm tseem ceeb hauv kev caij nkoj hauv av.

Tsis tas li ntawd, Arthur Holmes txoj kev xav yog dab tsi? Continental drift Ib qho teeb meem nrog rau kev xav nteg nyob rau hauv lub mechanism ntawm kev txav, thiab Holmes tau hais tias lub ntiaj teb lub mantle muaj convection hlwb uas dissipated radioactive cua sov thiab tsiv lub crust ntawm qhov chaw. Nws Cov Ntsiab Cai ntawm Physical Geology tau xaus nrog ib tshooj nyob rau sab av loj.

Nyob rau hauv no txoj kev, dab tsi yog convection tam sim no txoj kev xav?

Arthur Holmes postulated convection tam sim no txoj kev xav xyoo 1928-29. Kom nkag siab Holmes kev xav , ua ntej ntawm tag nrho cov koj yuav tsum muaj ib lub tswv yim ntawm convection tam sim no . Convection Tam sim no txhais tau tias yog tus txheej txheem ntawm kev ua kom kub tsis tu ncua ntawm cov kua lossis roj los ntawm cov txheej txheem hu ua Convection . ''

Thaum twg Arthur Holmes ua nws txoj kev tshawb pom?

Arthur Holmes pib kawm physics ntawm Imperial College of Science hauv London, tab sis hloov mus rau geology ua ntej kawm tiav xyoo 1910. Xyoo 1913, ua ntej nws txawm khwv tau. nws doctoral degree, nws tau npaj thawj lub sij hawm geological scale, raws li kev ncaj ncees tsis ntev los no nrhiav pom phenomenon ntawm radioactivity.
