Origin Of Water On Earth....

Did you know the water we drink is older than the earth?? hey guys welcome to my 19^th article and in this article let's talk about our life- water.

so let's start.....

Water

Unlike every other planet in our solar system, Earth’s surface is 70% liquid water, which is while useful for life, is also kind of weird, because everything we know about how and when our planet formed according to that Earth’s surface should be bone dry.

Origin Of Water

The story goes like this: our solar system formed from the collapse of a large cloud of dust and gas. The dense blob of gas at the center ignited to form the sun, which as a young, unstable star unleashed a fierce solar wind. Over time this stream of charged particles pushed the remaining gas cloud farther and farther out, leaving only solid particles behind to clump together into rocks and finally, the rocky planets of inner solar system that we know today came into existence. And here’s the problem: water, in the form of ice, couldn’t have been one of the solid particles that stuck around, because the early inner solar system was far too hot for frozen water, and any water vapor would have been blasted away by the solar wind.

So, if earth didn’t start off with water, how did we end up with water, how did we end up with such splendid oceans?

We know H2O wasn’t manufactured here because natural processes like combustion, breathing and photosynthesis create and destroy roughly equal amounts of water - and either way, the amount in question are so miniscule that they can’t account for the abundance of water on the planet.

Formation Of Water

Since Earth’s water was neither part of the original package nor manufactured here, so it must have flown in from far away, on meteoroids or comets or other bodies originated in the outer solar system where they were far enough from the sun for frozen water to survive. Comets being dirty ice balls ,are a logical candidate for source of water, but were ruled out when we discovered that they are far richer in heavy hydrogen (that’s hydrogen with a neutron as well as a proton in its nucleus) than Earth water. For every million hydrogen atoms in earth’s water about 150 are heavy ones, while typical comet water has twice that many. These mismatched chemical signatures suggested that Earth’s water could not have arrived on comet.

Source Of Water

It turns out that the most likely source for Earth’s water is a type of meteorite called Cabonaceous chondrit. “Chondrite” is just a name given to the stony meteoroids that most commonly strike the earth. But only the carbonaceous chondrites contain water as well as lots of carbon. They have water in them because they formed out beyond the sun’s “Frost line”, and what’s more their water levels of heavy hydrogen similar to that of earth water, strongly suggesting that these earth-crashers are the source of our ice caps, clouds, rivers and oceans.

And thus the water that turned our planet into a blue marble came, quite literally, out of the globe.

so yeah guys this is the end of this amazing article and thankyou so much for reading.

be healthy, die healthy.
