Relative dating animation
Click and drag sideways to move the seas in and out, and drag up and down to see what's beneath the water.There is no link back to this page and probably no need to return here, but if you want to revisit this page you can either click the Back button as many times as it takes to get here or close the program and start over.Even the heroes are individuals with their own wants and desires that don't always lead to peaceful relationships.The initial incarnation of the show lasted two seasons and sixty-five episodes.Examine how the final result allows you to infer the sequence of the rocks' formation.The links below are animations illustrating the principles of relative dating (determining the sequence of events) and to images of real examples on which to try out the principles. Click on each of the five small images below to bring up an animation about the seas moving in and out.Use the links below to explore available resources covering major concepts associated with the study of the history of the Earth.
Once, there were many gargoyles, but interactions with humanity have led to their species becoming endangered.
The main characters survived a purge in the year 994 thanks to a magical spell that made them permanently statues — at least, unless the castle which they were protecting were to ever "rise above the clouds". Billionaire David Xanatos (yes, that Xanatos) bought the ruined castle, then had it transported brick by brick from Scotland and rebuilt on top of his skyscraper in New York City.
This action broke the curse for good, reviving the dormant gargoyles in a land and time far from their home.
And it has seven protons, and it also has seven neutrons. So the different versions of a given element, those are each called isotopes. So anyway, we have our atmosphere, and then coming from our sun, we have what's commonly called cosmic rays, but they're actually not rays. You can view them as just single protons, which is the same thing as a hydrogen nucleus. But every now and then one of those neutrons will bump into one of the nitrogen-14'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. But this number 14 doesn't go down to 13 because it replaces it with itself. And now since it only has six protons, this is no longer nitrogen, by definition. And that proton that was bumped off just kind of gets emitted. But this process-- and once again, it's not a typical process, but it happens every now and then-- this is how carbon-14 forms. You can essentially view it as a nitrogen-14 where one of the protons is replaced with a neutron. It makes its way into oceans-- it's already in the air, but it completely mixes through the whole atmosphere-- and the air. 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. It gets put into plants, and then it gets put into the things that eat the plants. Well, the interesting thing is the only time you can take in this carbon-14 is while you're alive, while you're eating new things.
And we talk about the word isotope in the chemistry playlist. But this number up here can change depending on the number of neutrons you have. And every now and then-- and let's just be clear-- this isn't like a typical reaction. So instead of seven protons we now have six protons. And a proton that's just flying around, you could call that hydrogen 1. If it doesn't gain an electron, it's just a hydrogen ion, a positive ion, either way, or a hydrogen nucleus. And so this carbon-14, it's constantly being formed. I've just explained a mechanism where some of our body, even though carbon-12 is the most common isotope, some of our body, while we're living, gets made up of this carbon-14 thing.
