What is the age of the Earth?

[rmwilliamsll]

so how old would the steel be in my car, will it be the same date as my car? No....Its an example

google and see how you could date the steel in your car.
what are the potential radioactive elements that would be in the steel?
what are the potential daughter and parent elements?
does refining and/or processing the steel change these ratios?

you seem to believe that you can pick up a single atom and date it, however this is not a proper way to imagine radioactive dating. perhaps the best thing to do is start at the beginning and read:

and get the potential scientific background to intelligently discuss the issue.

An example of what?

how can you say a the earth is 4 billion years old based on a minute particle in the earth.

what if your right the rock was that old, what if God created the rock to play with and got bored with it after 4 billion years?

 

[simplyg123]

i have new hairs growing all the time if you figure the date of them to be 12 days, am i an infant?

for this topic see an excellent recent article in SciAm at:

the dating game

or this one on zircons in Australia:

i have new hairs growing all the time if you figure the date of them to be 12 days, am i an infant?

a false and misleading metaphor or analog to radioactive dating. you would have more credibility if you would take some time and read the links given above for your edification.

These are all complete strawman. Please, read up on the science and methods used in dating before making such arguments.

This has just become embarrassing.

the method of dating is not the point, the point is a rock, a pepple, a minute piece of the earth.

You folks are very educated i grant you that.

my percentage may be wrong, but i believe only 10 percent of the earth is Land or rock?

why is this little bit of evidence the back bone

So what's the other 90% of earth ?

The method of dating IS the point, because by focusing on the "pebble" issue, you are completely missing the point of radioactive dating. The important thing is not the pebble, but what is in it.

Most of the earth is made up of rock and metal, just at varying temperatures...

read the SciAm article on zircons referred above. it will go a long ways towards helping you understand the issues.

Huh? Do you know the concept of setting upper and lower limits?

You folks are very educated i grant you that.

Think on that for a second.

Huh? What's is the rest? Green cheese?

 

[calidog]

my percentage may be wrong, but i believe only 10 percent of the earth is Land or rock?

maybe even less if 1/3 of the surface of the earth is land and the core is a molten mass

 

[Melethiel]

If only 10% of the earth is rock, what is the rest made of?

 

[calidog]

So what's the other 90% of earth ?

water,a molten mass, and unknown (no-one has seen it or sampled it)

That's what I'm wondering ?

Though I guess you could go with molten Iron, Magma, Ect... (unless you go with some that say the earth is hollow)

 

[Melethiel]

Water is minimal. That "molten mass" still has to consist of something. Elements don't change identity simply because they change states.

what ever it is it is very hot.

 

[KerrMetric]

Not true. And we know how to check this. You don't need to see something to measure it and figure out its properties.

No one has ever "seen" gravity. No one has ever "seen" an electron.

You can figure out the Earth's internal structure without giong there.

Seismic (spelling?) and ultrasounding have been performed. Don't know what good that'll really do.

• Inner core: 1.7% of the Earth's mass; depth of 5,150-6,370 kilometers (3,219 - 3,981 miles)
  The inner core is solid and unattached to the mantle, suspended in the molten outer core. It is believed to have solidified as a result of pressure-freezing which occurs to most liquids when temperature decreases or pressure increases.
• Outer core: 30.8% of Earth's mass; depth of 2,890-5,150 kilometers (1,806 - 3,219 miles)
  The outer core is a hot, electrically conducting liquid within which convective motion occurs. This conductive layer combines with Earth's rotation to create a dynamo effect that maintains a system of electrical currents known as the Earth's magnetic field. It is also responsible for the subtle jerking of Earth's rotation. This layer is not as dense as pure molten iron, which indicates the presence of lighter elements. Scientists suspect that about 10% of the layer is composed of sulfur and/or oxygen because these elements are abundant in the cosmos and dissolve readily in molten iron.
• D": 3% of Earth's mass; depth of 2,700-2,890 kilometers (1,688 - 1,806 miles)
  This layer is 200 to 300 kilometers (125 to 188 miles) thick and represents about 4% of the mantle-crust mass. Although it is often identified as part of the lower mantle, seismic discontinuities suggest the D" layer might differ chemically from the lower mantle lying above it. Scientists theorize that the material either dissolved in the core, or was able to sink through the mantle but not into the core because of its density.
• Lower mantle: 49.2% of Earth's mass; depth of 650-2,890 kilometers (406 -1,806 miles)
  The lower mantle contains 72.9% of the mantle-crust mass and is probably composed mainly of silicon, magnesium, and oxygen. It probably also contains some iron, calcium, and aluminum. Scientists make these deductions by assuming the Earth has a similar abundance and proportion of cosmic elements as found in the Sun and primitive meteorites.
• Transition region: 7.5% of Earth's mass; depth of 400-650 kilometers (250-406 miles)
  The transition region or mesosphere (for middle mantle), sometimes called the fertile layer, contains 11.1% of the mantle-crust mass and is the source of basaltic magmas. It also contains calcium, aluminum, and garnet, which is a complex aluminum-bearing silicate mineral. This layer is dense when cold because of the garnet. It is buoyant when hot because these minerals melt easily to form basalt which can then rise through the upper layers as magma.
• Upper mantle: 10.3% of Earth's mass; depth of 10-400 kilometers (6 - 250 miles)
  The upper mantle contains 15.3% of the mantle-crust mass. Fragments have been excavated for our observation by eroded mountain belts and volcanic eruptions. Olivine (Mg,Fe)2SiO4 and pyroxene (Mg,Fe)SiO3 have been the primary minerals found in this way. These and other minerals are refractory and crystalline at high temperatures; therefore, most settle out of rising magma, either forming new crustal material or never leaving the mantle. Part of the upper mantle called the asthenosphere might be partially molten.
• Oceanic crust: 0.099% of Earth's mass; depth of 0-10 kilometers (0 - 6 miles)
  The oceanic crust contains 0.147% of the mantle-crust mass. The majority of the Earth's crust was made through volcanic activity. The oceanic ridge system, a 40,000-kilometer (25,000 mile) network of volcanoes, generates new oceanic crust at the rate of 17 km3 per year, covering the ocean floor with basalt. Hawaii and Iceland are two examples of the accumulation of basalt piles.
• Continental crust: 0.374% of Earth's mass; depth of 0-50 kilometers (0 - 31 miles).
  The continental crust contains 0.554% of the mantle-crust mass. This is the outer part of the Earth composed essentially of crystalline rocks. These are low-density buoyant minerals dominated mostly by quartz (SiO2) and feldspars (metal-poor silicates). The crust (both oceanic and continental) is the surface of the Earth; as such, it is the coldest part of our planet. Because cold rocks deform slowly, we refer to this rigid outer shell as the lithosphere (the rocky or strong layer).

Now since i am so scientifically stupid educate me to which of these you use for dating the earth
