Imitha emhlabeni

Mhlawumbi sakha sazibuza ukuba loluphi uhlobo lwemitha efikelela eMhlabeni, malunga noku kuyaziwa ukuba eyona nto ifunekayo kwimitha yelizwe yiplanethi imitha ekhutshwa liLanga, apho kwenzeka inkqubo eqhubekayo yokuguqula i-hydrogen ibe yi-helium, ekhupha ubushushu obukhulu. Olu bushushu luphuma ngaphakathi kwelanga luye kumphezulu walo ukusuka kuwo luye eMhlabeni.

La mandla adluliselwa eMhlabeni ngohlobo lwamaza ombane, anobude obahlukeneyo. Iseti yamaza ohlukeneyo ebude obukhutshwa ngumzimba ubizwa isikram lwalo mzimba kwaye unxulumene ngokusondeleyo neqondo lobushushu balo, ngohlobo lokuba ukuphakama kwalo, amafutshane amaza ombane akhutshwa ngawo.

Iseti yamaza ombane akhutshwa liLanga ibizwa ngokuba ngumjikelezo welanga kwaye kuyo, ngokuchanekileyo, amaza amaza amancinci kakhulu aphambili, njengoko ehambelana nobushushu bawo obuphezulu, obuvavanywa malunga 6.000 K (5.727 ° C).

Ngaphakathi kwimitha yelanga, iintlobo ezintathu zemitha esisiseko inokubonwa:

kwi Imisebe ye-Ultraviolet, kunye nobude obude phakathi kwe-0, 1 kunye ne-0,4 micrometer, kwaye ezothutha kunye ne-X-ray kunye ne-gamma ray ye-9% yamandla onke akhutshwa liLanga.

b) Imitha ebonakalayo ukukhanya

c) Inkqubo ye- imitha infrared, kunye ne-wavelengths ubukhulu becala phakathi kwe-0,78 kunye ne-3 microns (ibhendi ehambelana ne-infrared ekufuphi), kwaye ethutha i-50% eseleyo yamandla elanga.

Zonke ezi zinto zivela eLangeni kwaye zifikelela kumda ophezulu womoya wokuqala. Ngoku eli xabiso lithetha ukuba lifihla ukuhanjiswa ayilingani kakhulu yemitha phakathi kwamacala ahlukeneyo, ukungalingani okuphendula kwindlela inkqubo-yeatmosfera eyamkela imitha yelanga.
