presentation on isotope rock dating

By Youmna

Introduction into the process

- Natural process

- alpha

- beta

- Gamma

In order of weakest to strongest -> Alpha, Beta and Gamma.

Half Life and explaination

Below is a table which visaully showcases how it works.

One of Australia's oldest rock

zircon crystal around 4.4 billion years old.

Below is a micoscopic picture of it.

May possibly be the oldest piece of Earth.
