Earth Inside – Chemical Edition

earth chemical composition

From the latest post, i have been discussing about what inside of earth, and of course, Mount Chimborazo, Ecuador that make you astonished and say: awesome! Is this one of a earth’s wonder? (For who don’t know what happened in Mount Chimborazo, Ecuador, see my previous post – ??? or you can read here: the farthest place of the earth because the rotational of the earth)

Now, who know the mass of the Earth? Bingo! The answer is approximately 5.98 x 10^24 kg. Whooaaa!!! It is so heavy isn’t? Can’t you still figuring out? It means 5.980. kg! What can you imagime it? What is the term for it? Of course, there is no money that can compete that number. If there is, who? no one isn’t it? But there is One…. Do you know who? Our God! Bingo!

Like our body, Earth has a composition too, and it composed mostly by
iron 32,1%
oxygen 30,1%
silicon 15,1%
magnesium 13,9%
sulfur 2,9%
nickel 1,8%
calcium 1,5%
alumunium 1,4%
trace amounts of other elements 1,2%

While our Earth core region composed by
iron 88,8%
nickel 5,8%
sulfur 4,5%
trace elements 1%

At earth’s crust, there is a little more than 47% “thing” that we need everyday, Oxygen. Man who research about earth’s crust was F. W Clarke. He uncovered too that the more common rock constituents are nearly all oxides: chlorine, sulfur and fluorine. This oxides are important exceptions to this and their total amount in any rock (ussually much less that 1%). So, the rock near your house consist of chlorine, sulfur and fluorine. The other 99% more are in below (detail) :

F. W. Clarke’s Table of Crust Oxides Compound Formula Composition

silica SiO2 59.71%
alumina Al2O3 15.41%
lime CaO 4.90%
Magnesia MgO 4.36%
sodium oxide Na2O 3.55%
iron(II) oxide FeO 3.52%
potassium oxide K2O 2.80%
iron(III) oxide Fe2O3 2.63%
water H2O 1.52%
titanium dioxide TiO2 0.60%
phosphorus pentoxide P2O5 0.22%
Total 99.22%

What is silica? Silica principally as an acid, forming silicates and all the igneous rock (a rock that is a result – the vomit – from volcano)

Complicated huh? Well, you don’t have to memorize all of this note. You just need to know what is your earth consisted so that you are not an “alien” in here. At least, you have a little knowledge about the earth you where stand right now. Thanks for the attention! (Of course for who has  read my article, please fill up your comment! Is this aricle help you?)

Oh yeah, the last note i want to share with you, let’s love our planet! Keep it to have a longer live by throw garbage in a proper place! And avoid global warming! Love our planet! You can join! Be a earth guardian!

Thanks! Next topic will be more interesting! See ya!

  1. hi I have a question about the conditions in the core and outer core, are they always in a liquid state as I often see or are there parts of them that remain in a solid state?

    thanks michael

    1. Talking about Earth, actually, it can be divided in many layer, that sructured with complex chemical compund. From what i know, the interior structure of the Earth, similar to the outer, is layered. These layers can be defined by either their chemical or their rheological properties. The Earth has an outer silicate solid crust, a highly viscous mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core. Scientific understanding of Earth’s internal structure is based on observations of topography and bathymetry, observations of rock in outcrop, samples brought to the surface from greater depths by volcanic activity, analysis of the seismic waves that pass through the Earth, measurements of the gravity field of the Earth, and experiments with crystalline solids at pressures and temperatures characteristic of the Earth’s deep interior (source: wikipedia).

      Hope this help
