Relative age is the age of rocks and geologic features compared with other rocks and features nearby. You can tell by the dinosaur that I'm an old rock! But the absolute age is the exact age in years of rocks.
I'm the oldest rock because I'm on the bottom and this is true due to the law of superposition.
We are matching rocks but we are in different locations and this is called correlation.
I'm an old rock but I'm with the new rocks because of inclusion.
I've experienced unconformity because of the gaps and breaks in my rock record.
We are abundant but only last a short period of time and this is called index fossils.
We are three isotopes of hydrogen and isotopes that are atoms are the same element that have different numbers of neutrons.
When we fall into our half our value it's called half-life!
I'm an unstable rock turning into a stable rock and that is called radioactive decay.
