When archaeologists find relics or artifacts of ancient people (a group of relics that are found together are called "a find"), they meticulously analyze these remains, thus adding to the knowledge of human history. They describe each relic, noting every detail. They catalog each relic of a find, indicating every category to which it could logically belong. The archaeologists also date the relic, determining its age.
Archaeological dating is a highly developed aspect of the analysis of a relic. Basically, the methods of dating fall into 2 categories: methods of chronometric dating and methods of relative dating. Archaeologists need the results of both types of dating because each type provides distinctly important information.
Chronometric dating methods, as their name implies, measure time. Archaeologists use these methods to establish the number date of a relic or artifact, some as ancient as 3,500,000 B.C. One of the methods of chronometric dating is dendrochronology. This method uses the careful study of tree rings to establish the age of a relic or artifact.
Dendrochronology is based on the fact that trees produce a new layer, a ring of growth on their trunks (main stems) every year. Dendrochronologists can count these rings to tell the age of a tree. Because of variations in climate, some of the rings will be distinctive. For example, during a year with an unusually large amount of rain, a tree will grow more than in other years and produce a ring that is wider than any other ring. Conversely, during an exceptionally dry year, a tree will produce a distinctively narrow ring, the opposite of a wet year. The rings of trees in a particular area form recognizable patterns because they experience the same weather. Consequently, dendrochronologists can match the rings of one tree with the rings of another. (Essay, Part 1).

Hi Stardust,
Additionally, such dating can determine major Earth Changes in climate such as Earthquakes, Tsunami's, Volcanic Explosions, and dramatic temperature variation. Thanks for another exceptional read!!!
WOW!! Sweetheart Painted Diary, Kim!! I am so impressed and flattered by your overwhelming reviews on my little work. I just canŽt believe my eyes to see you here with me, on this day: the evening before Christmas...You are spending your precious time to give your valuable appraisals over my little work. IŽll be always grateful to you, my dear Kim. Your wise appraisals are so much WELCOMED for me. Thank you in advance for all your gentle reviews of my work, Ms. Painted Diary, dear Kim!! Merry Christmas, Kim!! Have a wonderful Happy New Year 2007 with all your loved ones!! More Scientific Essays like these ones are coming on your way, next year 2007. Hugs and Love Always, from Stardust.
Hi dear Erik!! Thank you for stopping by and reading my work!! I like to see you making comments over things I write. I certainly appreciate your sweet and friendly kindness, MON AMIE!! I speak 2 Languages fluently, and another 2, I can understand and speak a little. Those Languages are: English, Spanish, Italian and French. Io ti voglio benne, amore!! JeŽt aime!! Ti amo!! I love you!! Would you like more...?? More of me are coming next year in 2007. I should charge my inner energy first. I would take a BREAK FOR THE SUMMER, dear.

Dear Erik: I am so sorry for being so late in responding to your reply. I havenŽt been to this Forum for a long time, dear. I have just seen your review. Thank you for reading, dear!! I guess, you are about to hitting the CLUES. Although, you may be surprised to what you might find in there, sweetheart. You see, I Volunteer My Work!! I do Not have a Paid Job. I do it for a great cause and to achieve long term goals. My hubby and fellowman supports me. Thanks God!! I have no money on my own. He pays, and I do the rest...I have discovered many secrets from the Scientific World, only through him. I find it Not Fair to Reveal them, though. I shall keep them for myself from now on, until the end of my time. Anyway, the whole world wouldnŽt give a damn about me. Why should I be or not be??...I do the same to others now, what others have done to me in the past. That is Fair Play. Kind Regards, Erik. Sincerely, Starry.
