How the earth was made

have you ever wondered how the earth was made? well, I have and a few days ago I found out how the earth was made, I thought about who to share my learning with and my third or fourth idea was on my blog! so here is how the earth was made.

Did you know 4.6 billion years ago an enormous cloud of gas and dust called a solar nebular swirls in the milky way galaxy a new solar system was born our solar system to be exact. In a process known as the conservation of angular momentum. 

Gravity collapses the cloud turning in into a flattened spinning disk. 

The powerful gravity pulls most of the gas into the centre of the disk and this gas gradually condenses coalesces and ultimately forms our sun. Leftover gas and dust swirls around and slowly starts clumping together. 

Now the strong solar winds blast outward from the sun blowing lighter materials like hydrogen and helium far out heavier materials like dust and rocks resist the solar wind and remain close to the centre and it's this heavy material that begins clumping together eventually forming the prototypes of the inner rocky planets including planet earth. It's the earths dense rocky core that forms first, heavy materials like iron and nickle gravitate to the centre where as lighter materials drift to the outside eventually forming the earth's crust. 

Over millions of years the new earth begins trapping stray gas and it's powerful gravity and this gas eventually becomes our sacred life-saving atmosphere. But suddenly around 1 billion years after the earth is formed Theia a large mars-sized body floating freely in the new solar system crashes into earth causing near catastrophic damage, millions of pieces of the infant planet blast outward into space, some pieces were trapped in the earth's gravity ultimately becoming our moon. 

Today comets are rare in the inner solar system only appearing a few times every several decades but during the early primordial times comets were very abundant throughout the entire solar system it's believed these icy comets colliding with a young earth for the initial cause of water on our planets surface.

Of course since then earth has become the pleasant life bearing planet we know as home. We enjoy an abundance of vegetation, water, tools and technologies. 

We live a safe and protected life under our atmosphere, that is until the sun turns into a red giant and incinerates the entire planet and wipes out all evidence that earth was an existing planet, But not to worry we've got 5 billion years to figure that out and we can discuss this in another lesson.

Kia ora fellow teachers and students I see you've come back for another lesson about the earth. Just a quick question do you enjoy my interesting facts about the earth? let me know in the comments below. 

I  hope you enjoyed today's lesson I also hope you learnt something new today and every other day. Also in the comments write what you would like to learn or hear more from me in the future or tomorrow:)

Your sincerely

3 Interest Facts About Our Planet Earth

Planet Earth. That shiny blue marble that has fascinated humanity since they first began to walk across its surface. And why shouldn’t it fascinate us? In addition to being our home and the place where life as we know it originated, it remains the only planet we know of where life thrives. And over the course of the past few centuries, we have learned much about Earth, which has only deepened our fascination with it.

But how much does the average person really know about the planet Earth? You’ve lived on Planet Earth all of your life, but how much do you really know about the ground underneath your feet? You probably have lots of interesting facts rattling around in your brain, but here are 10 more interesting facts about Earth that you may, or may not know.'

1. Plate tectonics keep the earth comfortable:

Earth is the only planet in the solar system with "plate tectonics" So basically the outer crust is broken into regions called tectonic plates. Tectonic plates float above the magma interior of the earth and can move against one another. Tectonic resurfacing and geological activity such as earthquakes,volcanic eruptions and mountain-buildings are ignited when two of the many tectonic plates collide one plate will subduct (go underneath another) and when they pull apart fresh outer crust will be allowed to form. over long period of times the remnants of this life, rich in carbon are carried back into the interior of the earth and recycled. This pulls carbon out of the atmosphere, which makes sure we don't  suffer a runaway greenhouse affect   which is what happened to Venus.Without the action of the tectonic plates there would be no way to recycle carbon and the earth will become an overheated hellish place something the "Global warming" but I won't get into much of that because we can save that for another lesson on earth.

2. Earth is mostly Iron,oxygen and silicon:

If you could separate the earth out into piles of different types of materials you'd get 32.1% of iron 30.1% of oxygen 15.1% of silicon and 13.9% of magnesium. Of course most of this iron is actually located at the core of the Earth. If you could actually get down and sample the core, it would be 88% iron. And if you sampled the Earth’s crust, you’d find that 47% of it is oxygen.

3. The earth's molten iron core creates a magnetic field: 

The earth is basically an enormous magnet, with poles at top and bottom near to the actual geographic poles. The magnetic field extends thousands of kilometres out from the surface of the earth forming a region called magnetosphere scientists think that this magnetic field is generated by the molten outer core of the earth, where heat creates convection motions of conducting materials to generate electric currents. be grateful for the magnetosphere, 

without it particles from the sun's solar wind would hit the earth directly. Exposing the surface of the planet to significant amounts of radiation. Instead of the magnetosphere channels the solar wind around the Earth, protecting us from harm. Scientists have also theorized that Mars’ thin atmosphere is due to it having a weak magnetosphere compared to Earth’s, which allowed solar wind to slowly strip it away.

And that ladies and gentlemen was my really long informative 3 interesting facts about the earth if you would like to see more I would love to post more about the earth not only to teach me but to teach you guys as well. I hope you have all learnt something today in my 3 paged essay because I know I have. This has got nothing to do with school it is a post about something that I have learnt or already known and I want to share them publicly. 

I hope you learnt some new thing about our planet!

Ratings:
I would rate this book out of 10, 1000000/10
This book would be rated for 8+

I hope this book review has persuaded you to buy and read the book series "Secret seven" by Enid Blyton!  

Novel study word find | Secret Seven

This week for novel study I made a word find. If you want to see more novel study make sure to keep updated with my blog!!

The Big Jump | Word find

This is my word find for the book "The big jump"

The big jump | Sandra's perspective

I woke up today feeling the way I always do. Today is my first day monitoring the flying fox activity the highest activity throughout the whole entire camp. The first three people come on up and then fly their way down. Then Big Daddy comes up I put him in the safety harness he complained a little about how tight it was and then how lose it was so I explained to him how it had to be tight so when he goes down he doesn’t fall out and hurt himself. Big daddy is so scared he nearly backed out “I never have a student or anyone back out” Mr Jackson has already sent up the next participant Little Timmy and he sees Big daddy struggling to go down the flying fox. Little Timmy asks me “has anyone done a tandem jump today” “No” I say confused “why” I say. I put Little Timmy in the harness with Big Daddy and they went down at the same time. I can’t see much because they are going. I wait for a while and then I realise that all their weight is going to pull them down. They hit the tires at the bottom and I don’t know what happened to them so I just moved on!
