These include the uranium-thorium method, the potassium-argon method, and the rubidium-strontium method. Thermoluminescence (pronounced ther-moeloo-mi-NES-ence) dating is very useful for determining the age of pottery.When a piece of pottery is heated in a laboratory at temperatures more than 930°F (500°C), electrons from quartz and other minerals in the pottery clay emit light.We're sorry, this computer has been flagged for suspicious activity.If you are a member, we ask that you confirm your identity by entering in your email.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.Carbon-14, a radioactive form of the element carbon, is created in the atmosphere by cosmic rays (invisible, high-energy particles that constantly bombard Earth from all directions in space).

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.

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.
