First of all, what people consider a successful first date may differ greatly.

The technique of discovering out the identical order of the events that occurred so far grow to be commonly known as relative relationship. A second method is relative datingwhich places the order of geologic events by comparing rock layer positions without setting a specific time of formation.

What are the 5 very common tell-tale signs that tell you she's interested in you? The extension BC of the line AB represents the length of the surplus-labour. One method is absolute dating, which uses the half-life of radioactive isotopes to date the age of each rock sample.

Sometimes we only have one date with someone. They're cosmic particles.

You can view them as just single protons, which is the same thing as a hydrogen nucleus. They can also be alpha particles, which is the same thing as a helium nucleus.

And there's even a few electrons. And they're going to come in, and they're going to bump into things in our atmosphere, and they're actually going to form neutrons. So they're actually going to form neutrons. And we'll show a neutron with a lowercase n, and a 1 for its mass number.

And we don't write anything, because it has no protons down here. Like we had for nitrogen, we had seven protons. So it's not really an element. It is a subatomic particle. But you have these neutrons form. And every now and then-- and let's just be clear-- this isn't like a typical reaction. But every now and then one of those neutrons will bump into one of the nitrogen's in just the right way so that it bumps off one of the protons in the nitrogen and essentially replaces that proton with itself.

So let me make it clear.

So it bumps off one of the protons. So instead of seven protons we now have six protons. But this number 14 doesn't go down to 13 because it replaces it with itself.

I recommend all of the Amoeba Sister and Crash Course videos on Youtube. Age - Radiometric Dating: finishthetrail.com?v=I4AZbX_cZl0. Relative dating crash course relative dating is an important topic in ap relative and absolute dating video environmental finishthetrail.com is used to help relative dating .

So this still stays at And now since it only has six protons, this is no longer nitrogen, by definition. This is now carbon. And that proton that was bumped off just kind of gets emitted.

So then let me just do that in another color. So plus. And a proton that's just flying around, you could call that hydrogen 1. And it can gain an electron some ways.

If it doesn't gain an electron, it's just a hydrogen ion, a positive ion, either way, or a hydrogen nucleus. But this process-- and once again, it's not a typical process, but it happens every now and then-- this is how carbon forms. So this right here is carbon You can essentially view it as a nitrogen where one of the protons is replaced with a neutron. And what's interesting about this is this is constantly being formed in our atmosphere, not in huge quantities, but in reasonable quantities.

So let me write this down. Constant formation. And let me be very clear. Let's look at the periodic table over here.

So carbon by definition has six protons, but the typical isotope, the most common isotope of carbon is carbon So carbon is the most common. So most of the carbon in your body is carbon But what's interesting is that a small fraction of carbon forms, and then this carbon can then also combine with oxygen to form carbon dioxide.

And then that carbon dioxide gets absorbed into the rest of the atmosphere, into our oceans. It can be fixed by plants. When people talk about carbon fixation, they're really talking about using mainly light energy from the sun to take gaseous carbon and turn it into actual kind of organic tissue. And so this carbon, it's constantly being formed. It makes its way into oceans-- it's already in the air, but it completely mixes through the whole atmosphere-- and the air.

And then it makes its way into plants. And plants are really just made out of that fixed carbon, that carbon that was taken in gaseous form and put into, I guess you could say, into kind of a solid form, put it into a living form.

That's what wood pretty much is. It gets put into plants, and then it gets put into the things that eat the plants.

So that could be us. Now why is this even interesting?

I've just explained a mechanism where some of our body, even though carbon is the most common isotope, some of our body, while we're living, gets made up of this carbon thing. Well, the interesting thing is the only time you can take in this carbon is while you're alive, while you're eating new things.

Because as soon as you die and you get buried under the ground, there's no way for the carbon to become part of your tissue anymore because you're not eating anything with new carbon And what's interesting here is once you die, you're not going to get any new carbon And that carbon that you did have at you're death is going to decay via beta decay-- and we learned about this-- back into nitrogen So kind of this process reverses.

So it'll decay back into nitrogen, and in beta decay you emit an electron and an electron anti-neutrino. I won't go into the details of that.

But essentially what you have happening here is you have one of the neutrons is turning into a proton and emitting this stuff in the process.
