In which situation the earth was before it's turning in planet?

Answer 1

The Sun spewed out a lot of matter in a cigar-shaped filament called a solar nebula, when it was very young, some 4.5 billion years ago.

Planets formed as smaller planetesimals coalesced and became gravitationally attracted to one another and started to accrete to make ever-larger lumps and started to cool down.

Wikipedia states:

"Planetesimals are solid objects thought to exist in protoplanetary disks and in debris disks.

A widely accepted theory of planet formation, the so-called planetesimal hypothesis of Viktor Safronov, states that planets form out of dust grains that collide and stick to form larger and larger bodies. When the bodies reach sizes of approximately one kilometer, then they can attract each other directly through their mutual gravity, aiding further growth into moon-sized protoplanets enormously. This is how planetesimals are often defined.

Bodies that are smaller than planetesimals must rely on brownian motion or turbulent motions in the gas to cause the collisions that can lead to sticking. Alternatively, planetesimals can form in a very dense layer of dust grains that undergoes a collective gravitational instability in the mid-plane of a protoplanetary disk.

Many planetesimals may eventually break apart during violent collisions, but a few of the largest planetesimals can survive such encounters and continue to grow into protoplanets and later planets.

It is generally believed that by about 3.8 billion years ago, after a period known as the Late Heavy Bombardment, most of the planetesimals within the solar system had either been ejected from the Solar system entirely, into distant eccentric orbits such as the Oort cloud, or had collided with larger objects due to the regular gravitational nudges from the Jovian planets (particularly Jupiter and Neptune).

A few planetesimals may have been captured as moons, such as Phobos and Deimos (the moons of Mars), and many of the small high-inclination moons of the Jovian planets.

Planetesimals that have survived to the current day are valuable to scientists because they contain information about the birth of our solar system. Although their exteriors are subjected to intense solar radiation that can alter their chemistry, their interiors contain pristine material essentially untouched since the planetesimal was formed. This makes each planetesimal a 'time capsule', and their composition can tell us of the conditions in the Solar Nebula from which our planetary system was formed."

Wow, you got some interesting answers...One quite detailed and packed with information. I think it is important for you to notice some neat things right about you to get the picture of what might have happened...

Take a close look at the screen of your video monitor that you are looking at. Does it have a very thin coating of dust on it?
If so, you are seeing how large things (maybe with a static charge) attract dust and little sections of other things, and all these little bits of stuff try to clump together onto the bigger object. Well, that is how things work in real life, here on Earth and elsewhere. Now out in space, where you are talking about billions and billions of years ago, nobody knows for sure what happened, but it is fairly safe to assume that this attraction that large objects have for smaller objects was in effect back then. Molten metals (hot from some kind of massive explosion (maybe) are very dense and have certain mass which increases their pull on other objects, the larger ones becoming even larger, etc., etc. Being very hot, even molten, it is not hard to visualize them forming into a ball shape as the object becomes larger and larger.

Some objects might be sitting fairly still in the flow of things outward from the starting point of the explosion. Others which came from the center of the explosion might be moving very fast in the flow. As things collide, off center hits by the heavier objects cause a rotational spin on the main object, just like with pool balls in a game of Pool or Billiards. This happens right here on Earth and it is logical to assume that it also happened in space way back when all this began.

Gases have molecular weight also, and are attracted to heavier masses; either solids, or larger masses of gas. And from there we can project the various large objects in space collecting their atmospheres if they have sufficient gravity to keep the gases on their surfaces. Lacking sufficient gravity to retain the gases, the gas molecules might drift off into space until attracted by some other massive object. Supposedly this is what happened, and it is a good prospect for the correct story.

Hope this helps you out.

Earth was a primeval hell, a lifeless planet bombarded by massive asteroids and comets. The moon, much closer to Earth, loomed large in the sky. Instead of water, red hot lava streamed across the surface of our planet. Volcanoes spewed noxious gases into the primitive atmosphere. Scorched and battered, Earth was a planet under siege. Yet somehow, the world we call home emerged from these violent origins.

Answer 4

before earth became the earth we live now, it was a hot rock with a lot of volcanoes, lava spilling everywhere, no atmosphere..

but there was a big meteor came and strike the earth hardly. it breaks into 2 parts. one became the moon and the other part merged with earth..

the collision also made the earth spin rapidly. this made the earth cool down quicker.. the moon became a shield against smaller meteors.

Answer 5

u see, before being a plnet, there was a very hot and a very big star nebula which exploded and tiny bits and pieces got separated from it and there were large pieces too. after much time, these pieces cooled down and one of the piece was the Earth which had all the conditions necessary for life. hope i helped you.
