Measuring the Age of Earth
Introduction:
The age of the Earth is a topic of much debate and controversy in the scientific community. There are various methods of determining the age of the Earth, including carbon dating, radioactive decay, and geological evidence. However, the most accurate and widely accepted method of measuring the age of Earth is through the study of rocks and minerals.
Method of Measuring the Age of Earth:
The age of the Earth can be measured by calculating the age of rocks and minerals found on the Earth's surface. This is done by measuring the amount of radioactive isotopes in the rocks and minerals and comparing them to the amount of stable isotopes.
Radioactive isotopes decay at a known rate, which is called the half-life of the isotope. By measuring the amount of radioactive isotopes in a rock or mineral and comparing it to the amount of stable isotopes, scientists can calculate the age of the rock or mineral.
The oldest rocks on Earth are thought to be around 4.4 billion years old, and the age of the Earth is estimated to be around 4.54 billion years old.
Conclusion:
In conclusion, the age of the Earth can be measured by studying rocks and minerals on the Earth's surface. By measuring the amount of radioactive isotopes in the rocks and minerals and comparing them to the amount of stable isotopes, scientists can calculate the age of the Earth. The most accurate and widely accepted method of measuring the age of the Earth is through the study of rocks and minerals.

पृथ्वी की आयु का निर्धारण रेडियोधर्मी डेटिंग के आधार पर होता है। जब किसी रेडियोधर्मी पदार्थों (यूरेनियम, थोरियम, आदि) का विघटन होता है। तो उससे विकिरण के रूप में ऊष्मा निकलती है। इसी ऊष्मा ह्रास की दर के आधार पर पृथ्वी की आयु की गणना की जाती है।
