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 range of conventional radiocarbon dating is 30,000 to 40,000 years.

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.

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).

The older the pottery, the brighter the light that will be emitted.
