Dendrochronology: Also known as tree-ring dating, the science concerned with determining the age of trees by examining their growth rings.Half-life: Measurement of the time it takes for one-half of a radioactive substance to decay.Dating techniques are procedures used by scientists to determine the age of an object or a series of events.The two main types of dating methods are relative and absolute.Eventually, the entire ecosystem (community of plants and animals) of the planet, including humans, is filled with a concentration of carbon-14.As long as an organism is alive, the supply of carbon-14 is replenished.By measuring the amount of carbon-14 remaining, scientists can pinpoint the exact date of the organism's death.

Stratigraphy: Study of layers of rocks or the objects embedded within those layers.

This method is based on the assumption (which nearly always holds true) that deeper layers of rock were deposited earlier in Earth's history, and thus are older than more shallow layers.

ABSTRACT Rock glacier surfaces reflect debris accumulations produced, deposited and deformed during his- torical and Holocene time periods. Dating of such surfaces is difficult but can best be achieved by using a combi- nation of absolute and relative age-determination methods. Photogrammetry of present-day flow.… continue reading »

Unlike relative dating methods, absolute dating methods provide chronological estimates of the age of certain geological materials associated with fossils, and even direct age measurements of the fossil material itself. To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was.… continue reading »
