If the earth is about 5 billion yrs., why hasn't the center cooled by now & why does it run out of lava ?

Question

You would of thought by now the earth would of cooled sooner or later.

What keeps making lava, would the center eventually cave in from spewing out all the lava it has produced?

What is replacing it, there if no feed of materials to make more?

Answer 1

The Earth was formed molten and is very slowly cooling. Heat inputs, externally from the Sun and internally from radioactive materials, slow the cooling process.

Lava has nothing to do with the core. It is magma melted by the friction of crustal plates, and comes from the top layer of the mantle. As magma rises, the crust above subsides slightly to fill the space vacated. However, the volume of lava produced is small relative to the volume of the lithosphere.

Answer 2

Good question. That leads us to believe that the earth is not indeed 5 billion years ol or even close to it. Another good example is the Sun. It looses some 200 million tons of matter a day (or something like that) If the Sun were 5 billion years old like the earth is supposed to be then you add that much matter back into the Sun's mass for the last 5 billion years and the Sun would be so big the earth would be consumed by it. The truth is the earth is not 5 billion or even 5 million years old and these scientific facts only go to prove that the earth was indeed created about 6000 years ago just like the Bible teaches in Genesis 1:1.

In the begining God created the heavens and the earth.

Mainstream answers to this question speak of a lack of observational fortitude. Because the grid brings in the aetheric force from the sun the magma is continually heated.The mainstream does not deal in any logic that holds up to any real scrutiny and I can speak to the logical proofs of the cymatic grid ad infinitum,but if folks dont have any real desire for the truth ,they will never ask enough or the right questions to make themselves learned in earth science.When you have an understanding of the fact of the cymatic docahedron that is surrounding this planet,then you can start to understand the engineering that went into this universe. Its really a simple process and many have spoken of the music of the spheres for a long time,but the mainstream boys have everyone on the same dis-information track that they inhabit and their PHD's are at stake along with their grants and salary. so, I guess they as many before them ,will go the grave with their paradigm that holds no water. But the young folks can be apprised of a few realities so they may move forward,which is why I spend some time here.

Answer 4

gravitational pressure keeps everything molten, and if something is spewed out, more mass is pulled into the core and becomes molten. we stay roughly the same distance from the sun at all times, so the earth stays more or less the same temp. a change of a hundred degrees on the outer layer is nothing compared to the scope of absolute zero (super cold) or a few thousand degrees (super hot).

and theres a whole ****-load of versions of the bible out there (not to mention a few hundred other sets of ancient religions that all have books), so how does anyone know what ones right? answer, you cant. look up the word "faith". its going to have a part in there about not being able to prove your beliefs. so, anytime someone uses a religious answer to "prove" things about the world, its total conjecture. the idea that the world is only a few thousand years old is not only incorrect, and pretty much flat out stupid, but its been proven wrong by independent research done by people on every inhabited continet and civilized country on the planet. fossils, carbon dating, remnants of ancient civilizations, etc. all point to the earth being VERY VERY much older than that. if anyone wants to dispute this, please provide actual evidence to the contrary.

Answer 5

I think the others have taken care of the lava question - it recycles itself.

As far as 'cooling' goes, to transfer heat you need something to transfer to. There isn't a lot of matter surrounding the earth to lose the heat to. If it were immersed in water it might work better!

Second, we've got a huge heat source out there in the form of a star. The atmosphere acts to create a greenhouse, so even if we are losing small amounts of heat to the surrounding particles, we're getting plenty more heat generated.

And PastorJ, please do some research. If scientific theories were that easy to poke holes in don't you think someone would have realized by now?

Answer 6

Who says Earth isn't cooling?.. it sure is and thr is lot of literature available, i mean scientific n not Bibilic. The geothermal gradients have surely fallen thru the time, i.e from Archean to till date, which is reflected in the change in pattern of magmatism, ie. from Tonalitic (TTG suites) to Basaltic (BADR suites).

and dear core dosn't have to do anything with the Lava generated at least not now, coz differentiation is more or less over and it sure looks pretty stable, actually no one knows much about it, frankly.
Lava is product of just the molten plate, which incidentally depends more on the Pressure than temperature (Try searchin Decompresion Melting)


N ur last question the feed back, it sure is thr, the Law of Conservation of mass..... just chk out any subduction scene n u'll find out......

Answer 7

The earth's inner core is made out of mostly Iron, which we know is a form of metal. The core isn't in a liquid state so the iron if forced to rub or vibrate against eachother. This friction with the massive amount of pressure causes heat, alot of it. I think up to 9,000 degrees F. So, when the outer, less solid core recieves this heat, it causes magma. Scientists believe that with the tectonic plate movments, that it causes a circular motion with the magma. Heat pushes the magama up, and when it gets close to the inner mantle it starts to cool down, goes towards the core, and starts the process of heating the core up. Only in the thinner parts of the inner and outer mantel is this allowed to escape causing islands, volcanos, and sea volcanos.

Answer 8

Their is enough radioactive material in the core of the Earth to create a Geo-reactor that has sufficient material to keep things molten for the span of Geological time, by generating heat from fission.

Answer 9

Much of Earth's central heat is caused by radioactivity there and from the tremendous pressure of thousands of miles of rock pressing in on it from all directions.

Lava is recycled material. Once it reaches the surface it then cools, and over many millions of years, sometimes billions of years, it's gradually returned to the depths by plate tectonics.

Answer 10

Because of the weight of the earth upon it's self.The crushing pressure will not allow the earth's interior to cool,any time soon...tom science
