Amazing Fact About The Earth

 
Amazing fact number 5

Age

The age of the Earth is difficult to guess but researches are trying their best to do so. They are using the oldest rocks and meteorites discovered on Earth with radiometric age dating. Meteorites and Earth were formed at the same time which is the same time when the solar system was forming.

The hypothesis is that the growth of Earth began soon after the formation of the Cal-Al rich inclusion and the meteorites. The combination of rocks, crystals and meteorites which are found on the Earth and the aggregated minerals of different ages are the causes of the difficulties with the age determination.

The researches think that the Earth is 4,54 ± 0,05  billion years. The oldest material analyzed to date is small crystal of zircon from Western Australia (Jack Hills).   My guess is that the Earth looks pretty good for its age 🙂
