How is the age of the Earth estimated?

Answer 1

It is not determined by radiometric dating, that's for sure. Centretek needs to study this subject more. Noone is quite sure how old the earth is. Most of the time dates are assigned to fossils and rocks, not determined through unbiased research. So when you hear numbers like 4.6 billion years (or whatever the current accepted date is) it really means "Once upon a time..."
There are scientific ways to limit the age of the earth;
1. The earth is slowing down
2. The sun is shrinking
3. Earth's magnetic field is weakening
4. The moon is slowly moving away from the earth
5. The earth's atmosphere has not reached equilibrium yet

I would go into details but nobody likes reading looooong answers. Study this subject from both creationist and evolutionist sources. Don't take my or anyone else's word for it. Even if they claim to be an expert.
I am sure I will get a storm of insults and such from evolutionists. I am used to it. If you like debates then continue posting questions like this. If not then stay a mile away from them.

There are people on the other side of those computers. Please be civil if you want to be taken seriously. Your response is both juvenile and offensive, therefore weakening your argument, not strengthening it. By the way; those who use poor spelling should not call other people idiots...

Answer 2

Kdanley the suns not getting smaller its getting bigger. as its expands it gets more unstable and when it gets the its peak it blows up makeing a smaller star or a blackhole. and the age of the earth is estimated by fossiles rocks the older the rock they find the older they estimate the earth. also do this by weather and the gases increase/deacrese speed they calculate how much there is and how retrace the estimated speed of the gas increase/deacrese in the air to get to the point were there is no gas and then the get an "inacurate" age of the earth.

Answer 3

The age of the earth is established by its cooling down from a moulten ball to the present day. Its just the same as boiling a kettle to make a cup of coffee, once the kettle has knocked itself off the water inside begins to cool down from the outside first. Once the chemical compound of the earth is established a heating and cooling constant can be calculated and since the earth is still moulten in the centre it is easier to find the original temperature.

Answer 4

The scientists use some kind of system known as carbon-dating. If gives the approximate astronomical age of substances and by assessing rocks from different periods, the scientists try to estimate the age of the earth.

Answer 5

From the unique presence of a particular isotope of lead resulting from a decay process starting with uranium. The ratios of these isotopes within the earth's crust lead to an unequivocal date of 4.5B years. The agenda of the IDiots and the Creationshits is to postul8 an early earth and creation so to deny the possibility of natural selection and natural mutation over time to create the diversity of life and intelligence on our planet!
PS do not even thnk 'bout it!..I have trakked down ur scum-kind b4 and destroyed yous..u will simply bcum 1 off the disappeared. Darwinian evolution demands that unsuccessfull peeps like u DO NOT contribute to the gene-pool!

Answer 6

Anyone who asks you to think about this from all points of view, including a creationist point of view, really wants you to look at it from a creationist point of view.

The fact is, if you look at the processes operating on Earth today, like plate tectonics, mountain building, evolution, weathering, erosion, sedimentation, lithification, fossilization, metamorphism, etc. they all indicate that the Earth is billions of years old. But we can't assign an exact numerical age based on running these processes in reverse, we just get the idea that Earth must be several billion years old.

The only thing that we can use to get numerical dates is radiometric dating. Radiometric dating is, in fact, very accurate and very precise. (This is something that the creationists can't stand and they do everything they can to try to convince you otherwise, but a basic understanding of physics and chemistry should allow you to understand the reality of how radiometric dating works.)

Radiometric dating of the oldest minerals on Earth yields an age of about 4.2 billions years. Well, that's not the 4.55 billion that's in all the geology textbooks, so, what's the deal?
Well, the Earth is a dynamic place, the crust always being recycled back into the mantle. If you think about it, we were lucky to find any materials even that old. And, it turns out that these very old minerals (zircons) were found in sedimentary rocks - since sedimentary rocks form from pre-existing rocks and it takes a long time form them to form, it's clear that the Earth is older than 4.2 billion years.

To find out exactly how old Earth is, we have to turn to the only examples we have of other rocks that were formed at the same time Earth and all the other planets were formed - meteorites. Meteorites are the oldest materials in the solar system that have not been altered since their formation by any geologic processes. Radiometric dating of meteorites yields an age of 4.55 billion years. And it's not just a few meteorites, it's hundreds of them, of all different types, that have been measured by different people, at different labs all over the world, and they all yield a consistent age of 4.55 billion years.

Answer 7

The Bible tells the story of creation.When you don't want to believe in God & His version,then you are open to many variatons! God made the world & all that we can see from it,in Six days.Rested on the seventh(sabbath)(now known as saturday).The suggnificance of the number 7 in the Bible would suggest that the world & everything on it,is not older than Seven thousand years! Please read the account of creation for yourself in a easy-to-read Bible & i am sure you could be sattisfied with the answers therein.God bless.

Answer 8

Carbon dating, scientists have settled on the age of the earth at about 4.6 billion years.

Answer 9

You take the square root of the diameter of the planet times its mass. This has to then be divided by the speed of rotation, measured in m/s and multiplied by the distance from the planet in question to the centre of its galaxy, in our case, the milky way. Hope that helps.
