Carbon dating artifacts

By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.Though still heavily used, relative dating is now augmented by several modern dating techniques.

Marx predicted workers would take control of the factories, but it seems that communist revolutions have occurred in states that were basically feudal.

Green plants absorb the carbon dioxide, so the population of carbon-14 molecules is continually replenished until the plant dies.

Carbon-14 is also passed onto the animals that eat those plants.

But archaeology’s aim to understand mankind is a noble endeavor that goes beyond uncovering buried treasures, gathering information, and dating events.

It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself.
