Radioactive decay: The predictable manner in which a population of atoms of a radioactive element spontaneously disintegrate over time.Stratigraphy: Study of layers of rocks or the objects embedded within those layers.Since certain species of animals existed on Earth at specific times in history, the fossils or remains of such animals embedded within those successive layers of rock also help scientists determine the age of the layers.Similarly, pollen grains released by seed-bearing plants became fossilized in rock layers.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.

Absolute dating methods are used to determine an actual date in years for the age of an object.

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.

By measuring the amount of original and transformed atoms in an object, scientists can determine the age of that object.

Cosmic rays: Invisible, high-energy particles that constantly bombard Earth from all directions in space.

  1. Radiocarbon dating also referred to as carbon dating or carbon-14 dating is a method for determining the age of an object containing organic material by using the.

  2. Most scientists and many Christians believe that the radiometric dating methods prove that the earth is 4.5 billion years old. Recent research shows otherwise.

  3. 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.

  4. Crossdating is the core principle of dendrochronology. Our study compared two techniques for measuring and crossdating tree rings using Juniperus virginiana L.
