Because you determine the ratio between different elements or isotopes. When one of the elements you are looking at is either added to or removed from your sample, this ratio gets distorted, and you won't be able to make a correct guess of the age of your sample.

A well-defined group of objects that transfer energy to one another?
The laws of nature would make this impossible, some energy always escapes.
Is earth an open or closed system in terms of matter?
It's both closed and open systems.
Explain why the Earth is essentially a closed system in terms of matter and if it also a?
Earth is essentially a closed system in terms of matter because it does not let matter come in or not.
What type of circulatory system does coral have?
Coral don't have circulatory systems. They just have a gastrovascular system!
What was the first solids that formed on the Earth?
The oldest mineral, a zircon from the Jack Hills of Australia, which has a radiometric date of about 4.4 billion years - a brief time after the formation of our Solar system. This zircon comes from a gneiss terrane.
Why can't radiometric dating be used with accuracy on metamorphic rocks?
An accurate radiometric date can be obtained only if the mineral remained a closed system during the entire period since its formation this is why radiometric dating can't be used with accuracy.
What radiometric system applies to the Jurassic time period?
The Jurassic is an age that began about 200 million years ago and stretched for about 50 million years to about 150 million years ago. Radiometric dating can identify certain materials as being from that period, but we don't have a "radiometric system" for the Jurassic, per se. Radiometric dating is part of the radiometric (from radioactive measuring) system we use to investigate a number of different things, including the age of materials found on the earth and elsewhere.
What evidence indicates our solar system is about 4.5 billion years old?
The age of the Solar System HAS TO BE at least as much as that of the oldest rocks found on Earth, other planets, or asteroids (if you assume that those rocks come from the Solar System) - and that's what has been found. And that's the approximate age of the oldest rocks found. The main methods used rely on radiometric dating. For more information, check the Wikipedia (or other sources) for:* Age of the Earth* Radiometric dating
What is the use of a metal lead relating it with uranium?
The system uranium-lead is very important for radiometric dating of rocks (ages between 106 and 5.109 years).
What eons old is the world today?
Our Earth and most of the Solar System is about 4.5x109 years old. This is established by radiometric dating, commonly by the uranium - lead series.
