Example of relative dating methods Chatting online right now

The concept is considered by uniformitarian geologists to be a major breakthrough in scientific reasoning by establishing a rational basis for relative time measurements.

However, unlike tree-ring dating -- in which each ring is a measure of 1 year's growth -- no precise rate of deposition can be determined for most of the rock layers.

We'll even visit the Grand Canyon to solve the mystery of the Great Unconformity!

Imagine that you're a geologist, studying the amazing rock formations of the Grand Canyon.

Your goal is to study the smooth, parallel layers of rock to learn how the land built up over geologic time.

Now imagine that you come upon a formation like this: What do you think of it? How can you make any conclusions about rock layers that make such a crazy arrangement?

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.

Relative dating is a dating method that used to determine determine the relative ages of geologic strata, artifacts, historical events, etc.

This technique does not give specific ages to items.
