Water contains oxygen. The Miller-Urey experiment used some water and was energy activated using some electrical discharge intended to simulate lightning conditions, believed to induce reactions in the inanimate matter used to produce chemical reactions that created compounds believed to be consistent with what were needed to form a complete initial organism.

The electrical discharge, if intense enough, is sufficient to induce electrolysis, which separates water into H and O, but the amount of O produced was not large enough to fundamentally negatively affect the experiment. Nevertheless, the experiment used the wrong basic inanimate matter, principally the atmosphere, and did not produce the essential compounds to show viability in creating the conditions for the origin of life.

For giving you understanding ; we need Free O2 but Oxygen is also available in H20 right why dont we use it !!

As the early atmosphere was reducing as there was no free oxygen but it was later produced by chemoautotrophic bacteria !! Living thing release O2 in atmosphere thus making it oxidising in nature and then life evolves !!

babunello [35]
Salutations!

A meander that has been cut off from the river is called oxbow lake. I will now give an explanation on how an oxbow lake is formed.

An oxbow lake is a narrow U-shaped lake near a river. Its a meander that got cut off.

As erosion, continues, the neck of the meander is worn away. It gets narrower and narrower. Then, during flooding, the river takes a shortcut - straight across the neck. Soon the loop of the meander gets sealed off. It turns into an oxbow lake. In time, the lake will get covered with weeds, and fill with soil, and disappear. 

Hope I helped (:

Have a great day!
