Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. Radioactive elements decay. The universe is full of naturally occurring radioactive elements. Radioactive atoms are inherently unstable; over time, radioactive "parent atoms" decay into stable "daughter atoms." When molten rock cools, forming what are called igneous .
1. How do scientists find the age of planets (date samples) or planetary time (relative age and absolute age)?We have rocks from the Moon (brought back), meteorites, and rocks that we know came from Mars.

Explain how radiometric age dating works. Why does the parent material never totally disappear completely even after many half lives? Radiometric age dating is where specimens are undergone examination to see how old the specimen or the age of the rocks or minerals that saved the specimen are. It never goes away because there is always pieces or bits of the parent material that are left.
The earth is billions of years old. The most useful methods for measuring the ages of geologic materials are the radiometric methods-the ones that make use of radioactive parent isotopes and their stable daughter products, as preserved in rocks, minerals, or other geologic materials. The main condition for the method is that the production rate of isotopes stays the same through ages, i.e.
