WebMar 23, 2016 · 1 Answer Don Mac Mar 23, 2016 Because the elements used for dating need to be re-set by volcanism. Explanation: Radioactive elements decay at a certain constant rate and this is the basis of radiometric dating. But, the decay elements need to be set, much like you would re-set a stop watch for a runner, to ensure an accurate measurement. WebWe can then use radioactive age dating in order to date the ages of the surfaces (when the rocks first formed, i.e. when the lava cooled and crystallized). We also have meteorites from asteroids and can date them, too. These are the surfaces that we can get absolute ages for.
