here it is,,,,,,,,,,,

the earth formation,,,,,,✨✨✨✨✨✨✨

Note that I'm no Geologist, just a casual observer! So I did some research and lots of speculation!

Earth's formation



The Earth was formed a few billion years ago, when the sun was formed! It all started in our local cluster or the Orion arm!

Anomaly

A cloud of gas in the cluster was disturbed, either by an external or internal source fo gravity, it then created a focus point, where all the gas started gathering.

Compression

The cloud grew smaller and denser! With the increased density, there was increased temperature and gravity!

Ignition

At a certain point the cloud ignited creating a series of nuclear explosions, blasting away all the heavy material formed by the explosions. However, the local gravity was so strong that most material just started falling back into the now new born sun. Also the chain reaction caused by the ignition was contained within the sun.

Running

As the material was falling back into the sun, it also gathered together, under the effect of gravity! The increased mass caused the now proto-planets to accelerate, those that acquired enough mass to generate it's own gravity field, deviated from the sun by magnetic repulsion and stayed in orbit around the sun. Besides, they were in a arched trajectory anyways! The higher the field the further the planet stayed! At that's how I imagine the solar system runs!



The Earth

was created in the same fashion, but also was the planet in the right spot to collect water, keep it in liquid state on its surface, and had the right composition to have the magnetosphere!



Earth's composition

The Earth has many layers.

The crust is the rocky part we live on.

The mantle is the bed underneath the Crust.

Then we have the Outer Core, made out of liquid metal.

Finally the Core is the denser and hotter layer of the planet.
