Meteorites are among the oldest objects we know about - formed about 4. But how do scientists know this? This article describes the principles and methods used to make that determination. There are well-known methods of finding the ages of some natural objects.

Earth's Creation and the Concept of Deep Time. The Principle of Superposition tells us that deeper layers of rock are older than shallower layers. Principle of Cross-Cutting tells us that the radiological colored granite must be older than the darker basalt dike intruding the granite. 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 relative of naturally occurring radiometric elements. Radioactive atoms are inherently absolute; over time, radiological "parent atoms" decay into stable "daughter age. When radioactive rock cools, forming what are called radiological rocks, radioactive atoms are trapped inside.

What Is Half-Life?

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 rocks, radioactive atoms are trapped inside. Afterwards, they decay at a predictable rate.
