Define radiometric dating of fossils

Also called absolute dating, scientists use the decay of radioactive elements within the fossils or the rocks around the fossils to determine the age of the organism that was preserved.

This technique relies on the property of half-life.

But, how can we determine how old a rock formation is, if it hasn’t previously been dated?

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. By measuring the quantity of unstable atoms left in a rock and comparing it to the quantity of stable daughter atoms in the rock, scientists can estimate the amount of time that has passed since that rock formed.

Index fossils are fossils that are known to only occur within a very specific age range.

Ever wonder how scientists concluded the age of the earth to be about 4.6 billion years old or how geologists determined the ages of caverns, rocks, volcanoes and the Himalayas? Well, scientists are able to answer all of these wondrous questions and more by use of a process called radiometric or radioactive dating.

Elements occur naturally in the earth, and they can tell us a lot about our Earth's past.
