Describe one method of relative dating

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.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.The age of the remains of plants, animals, and other organic material can be determined by measuring the amount of carbon-14 contained in that material.

Cosmic rays: Invisible, high-energy particles that constantly bombard Earth from all directions in space.With sensitive instrumentation, this range can be extended to 70,000 years.In addition to the radiocarbon dating technique, scientists have developed other dating methods based on the transformation of one element into another.Absolute dates must agree with dates from other relative methods in order to be valid.The most widely used and accepted form of absolute dating is radioactive decay dating. Radioactive decay refers to the process in which a radioactive form of an element is converted into a nonradioactive product at a regular rate.
