THE MYSTERY OF THE EARTH RESOLVED
IT IS A WRITE WITH PROSE AND POETRY INTER WOVEN AGAIN IN THE FORMAT OF A QUESTIONNAIRE ANSWERED
1.What is the history of the Earth and the Solar System related to?
Science is transparent and is no way a mystery
It`s the body, not its attire, it`s a truth not a lie
And it`s fact and not fiction and sell your illusive dreams
To buy Science the predecessor and the successor.
The history of the Earth encompasses the development of the planet Earth from its formation to the present day. Nearly all branches of natural science have contributed to the understanding of the main events of the Earth's past after the Big Bang.
2.What is the hypothesis of the formation of the Solar System?
A thesis and yet another!
Man got it right from inquisitiveness,
He wrote it in words clear
And spoke of it louder and louder.
The standard model for the formation of the Solar System (including the Earth) is the solar nebula hypothesis.In this model, the Solar system formed from a large, rotating cloud of interstellar dust and gas called the solar nebula. It was composed of hydrogen and helium created shortly after the Big Bang 13.7 billion years ago and heavier elements ejected by supernovae. About 4.5 billion years ago the nebula began a contraction that was triggered by the shock wave of a nearby supernova. That shock wave made the nebula rotate as well. As the cloud began to accelerate, its angular momentum, gravity and inertia flattened it into a protoplanetary disk perpendicular to its axis of rotation. Small perturbations due to collisions and the angular momentum of other large debris created the means by which kilometre-sized protoplanets began to form, orbiting the nebular centre.
3.What happened to the initial nebula later?
Unsound minds go roaming elsewhere
But the sound ones beg for a hearing at times!
Stoic silence engulfs your tales
As our own science remains a winner in silence.
The centre of the nebula, not having much angular momentum, collapsed rapidly, the compression heating it until nuclear fusion of hydrogen into helium began. After more contraction, a T Tauri star ignited and evolved into the Sun. Meanwhile, in the outer part of the nebula gravity caused matter to condense around density perturbations and dust particles, and the rest of the protoplanetary disk began separating into rings.
4. What happened in the next immediate stage?
What is the age of the Earth? When did the Earth get formed?
Then began our brief destiny
The span of a worthless matter getting into a worth you deem right.
Sooner came the phases inevitable and the final one will be
That to be shadowed by man`s foolery later.
In a process known as runaway accretion, successively larger fragments of dust and debris clumped together to form planets.. The solar wind of the newly formed T Tauri star cleared out most of the material in the disk that had not already condensed into larger bodies.
The same process is expected to produce accretion disks around virtually all newly forming stars in the universe, some of which yield planets.Earth was formed around 4.54 billion (4.54×109) years ago by accretion from the solar nebula. Volcanic outgassing was instrumental behind the creation of the primordial atmosphere.But it contained almost no oxygen and would have been toxic to humans and most modern life. Much of the Earth was molten afterwards because of extreme volcanism and frequent collisions with other bodies.
5.Was it the proto-Earth?
And longer phase followed the matter born,
And time and again the strange things went on.
Greater impacts waited by the matter
And our proto-Earth was on its way.
Yes. The proto-Earth grew by accretion until its interior was hot enough to melt the heavy, siderophile metals. Having higher densities than the silicates, these metals sank. This so-called iron catastrophe resulted in the separation of a primitive mantle and a (metallic) core only 10 million years after the Earth began to form, producing the layered structure of Earth and setting up the formation of Earth's magnetic field.J. A. Jacobs was the first to suggest that the inner core—a solid centre distinct from the liquid outer core—is freesing and growing out of the liquid outer core due to the gradual cooling of Earth's interior (about 100 degrees Celsius per billion years. Extrapolations on these observations estimate that the inner core formed approximately 2-4 billion years ago, from what was previously an entirely molten core. Earth's first atmosphere, captured from the solar nebula, was composed of light (atmophile) elements from the solar nebula, mostly hydrogen and helium. A combination of the solar wind and Earth's heat would have driven off this atmosphere, as a result of which the atmosphere is now depleted in these elements compared to cosmic abundances.
6.What caused the formation of the Moon?
Like a beautiful dancer she mesmerises
And we fall prey to her charms.
One very large collision of an external body resulted in a phase that rewrote the story of life in the earth. It was responsible for tilting the Earth at an angle and the same formed the Moon the only satellite of the Earth.
7.How did life get formed on the Earth? Was it a case of chance existence? What is the future of life going to be?
God did it - thus you lied for long and
A few days you fixed as the term for it to emerge!
Know for yourselves the enlightened souls,
The life wasn`t formed by a force on it`s will
It was, is and will be a case of chance existence.
When the cosmic bombardments ceased, the earth started getting cooled and then it was formed into a solid crust. Water that was brought here by comets and asteroids condensed into clouds and the oceans took shape. Earth was finally hospitable to life, and the earliest forms that arose enriched the atmosphere with oxygen. Life on Earth remained small and microscopic for at least one billion years. It was about 580 million years ago, complex multicellular life arose, and during the Cambrian period it experienced a rapid diversification into most major phyla.
Man and every other living being are here just for the conditions of a bio-atmosphere being formed accidently. That is why there is no life on the other planets though they too continue to exist. Life on the earth is a matter of CHANCE and it is not the result of a great PLANNING. As many as 87% of living beings are struggling for survival among the variety species and man will have the toughest struggle for survival as he has been digging his graveyard for the last 6000 years or so in the name of progress, wealth making and his pursuit of pleasures un natural. Minus man the earth may/would permit better life for the rest of the living beings with less intelligence though man`s ugly fight for survival alone can eliminate him later. But it is going to happen that after man`s final extinction there may be phase of other living beings.
8.When did humans originate on the Earth?
First monkey and his mate were there later,
Not the first man and his satan-tempted better half.
Man emerged from the chimpanzee
And not from a handful of earth.
This is the area of the greatest controversy in religion and science. The fact is around six million years ago, the primate lineage of living organism led first to the evolution/origin of chimpanzees (the closest relatives of humans) .Next they got diverged from the lineage and resulted in the origin of modern humans.
9.What are the reported Biological and Geological changes going on the earth?
Innumerable are they,
Inevitable are they too.
We shall end somewhere for sure
As ours is a mere CHANCE EXISTENCE ever.
Biological and geological change has been constantly occurring on our planet since the time of its formation. Organisms continuously evolve, taking on new forms or going extinct in response to an ever-changing planet. The process of plate tectonics has played a major role in the shaping of Earth's oceans and continents, as well as the life they harbor. The biosphere, in turn, has had a significant effect on the atmosphere and other biotic conditions on the planet, such as the formation of the ozone layer, the proliferation of oxygen, and the creation of soil.
10.Why are human beings unable to understand such changes taking place on the earth? How long do we live when compared to the age of the universe?
'Smaller' than animals in intelligence,
Wiser than things 'mute and non-alive'
Man knows not things often
For he lives for a bubble`s term indeed.
We can live only for about 100-110 years utmost. So we humans are unable to perceive the changes due to our relatively brief life
spans.But these changes are ongoing and will continue for the next few billion years with or without man on the earth..
To be precise, when compared to the age of the universe, man lives for only 1/10 parts of a second even if he lives for 100 years in average. Within that time span man cannot understand the phases of any evolution going on in the earth. If man can live upto half a million years, he can understand the concept and feel the reality of the absolute changes.But that can never happen!

Poet's Notes about The Poem
The origin of the EARTH and the type of life formed there perhaps are the two areas that may irritate your thoughts founded on beliefs. But I was on a mission to keep aside the ornamental poetry for a few weeks and to go for prose here. Thank you for reading this write. It is like reading the biography of our Mother Earth
