$UV$ radiations

Vedclass · Answer

(D) On the early Earth,high-energy $UV$ radiations from the sun caused the photolysis of water vapor $(2H_{2}O \xrightarrow{UV} 2H_{2} + O_{2})$.Since hydrogen is a light gas,it escaped into space.The released oxygen combined with ammonia $(NH_{3})$ and methane $(CH_{4})$ to form water $(H_{2}O)$,carbon dioxide $(CO_{2})$,and other compounds.

Which of the following broke down water into hydrogen and oxygen on the early Earth?
