Analyizing the compstion of it
Analyzing each layer
Computers can determine the age of an object through a carbon dating, This is also known as fission-track dating and is commonly used by anthropologists and archaeologists.
magnetometer
Scientists use the relative amount of stable and unstable isotopes in an object to determine its age.
That it lets you determine the age of an object, with a fairly high precision.
Radiometric or isotopic dating.
[object Object]
You can use a ruler to determine how long a object is
Look up at the sky, and its second star to the right strait on till morning!
The mass divided my the volume determine the density of an object
The general term is "radiometric dating. If the isotope is carbon, then it is "carbon dating"
The formula for density is an object's mass, divided by its volume. If you have both those quantities, you can determine the object's density.
