Beginning of Earth
A short overview :
Is the home of every life-form known to us in the universe it's age is about a third of the age of the universe and admitted it is there. Yeah,
Streams lakes and aquifers are witherms. This gives us energy, but how did existence and what's it made of 4.6 billion years ago Earth was created from the remnants of dead stars the collected in a giant dirty gas cloud. The gas bill became denser it.
Center and formed an accretion disk small particle started coming together and building larger and larger objects until they form the objects. We call this process to 10 to 20 million years and is still not very well understood at about this time with the solar system was Young Building The Joint subject-object have been more massive. It might have destroyed us material life was smashed out into orbit, which is the biggest satellite in relation to its planets in the Solar System.
But something strange down has ever come close to me is asteroids before know, what about this volume compared to the surface of us, isn't it? Wasn't water and we don't use that land 97.5 percent is sailing water. Well only 2.5 percent is fresh water. The fresh water is 69% ice and snow sisters and our granddaughters and a about 1% make up the remaining ground Waters,. But even this small part is mostly Frozen only a tiny part about water is actually lakes and rivers and even Tanya part is bound in living things. So friendly the Earth cooled down and the surface for listen trust but inside the earth hot rod continue to swirl about moving the cross from low and break it apart. This process is called plate tectonics and is happening right out.
Let's just say that the crust of Earth consists of separate own plates that move around as they meet they crumbled and create Mighty Mountains for finally comes back down deeper into the Earth creating dig.
That's the way please make some noise for whatever is the deepest penetration from elements as mountains and trenches are Mighty In Deed, but when you look at the open cross section, You can very quick five and seventy dollars, by the way that it often to 60 kilometers.
Some rare pictures series of crust of Earth.
Just comes to my mental meters deep down to the outer corners, of course a liquid layer of iron nickel Cobalt 2266 kilometers thick temperatures vary from 4,000 degrees Celsius. The 5703 Celsius in the center is the inner core. It's mostly solid double major. Slowly growing at an estimated rate of about one millimeter per year this small layer of crystallized milk products are former molten metal is where we live. It's an invisible phenomenon that diverts high-energy particles coming from the Sun and other sources and having for a stable environment with comparatively little radiation impact on Earth, but why is it there?
We didn't really know a terrible that about that. We know it has something to do with the core of the earth inside this metal sphere large electrical currents flowing complicated atoms. They causing magnetic field and sort of stabilize itself according to the laws of electrodynamics. This entire system is called the Dynamo, but don't let this fool you into thinking we have it all figured out speaking of breathtaking information about the area stuff that surrounds Us by volume dry air consists mostly of nitrogen oxygen carbon a variable amount of water vapor and small. It's of other gases humans are very dependent on the lowest layer of the atmosphere the troposphere where the weather is. It's 12 kilometers thick on average about that is the stress fear, which is where the ozone layer protects us from the sun's most aggressive type of light about that is the mesosphere the coolest place on Earth with an average temperature around - 85 degrees Celsius as about $80 .
