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!
