Pros and cons of dating objects with carbon 14 articles

When carbon-14 falls to Earth, it is absorbed by plants.These plants are eaten by animals who, in turn, are eaten by even larger animals.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 dating methods are used to determine an actual date in years for the age of an object.

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.

The successive layers of rock represent successive intervals of time.

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.
