Explain how radioactive and radiometric dating are related Freeadultchats
Basically, fossils and rock found in lower strata are older than those found in higher strata because lower objects must have been deposited first, while higher objects were deposited last.
Relative dating helps determine what came first and what followed, but doesn't help determine actual age.
Atmospheric carbon in CO2 has a fixed ratio of C14 to C12.
radioactivity is where an element has an electron configuration where it cannot be stable and holds to make electrons and the electrons just want to 'bust' out.
Free 5-day trial Radiometric dating is a method used to determine the age of rocks and other materials based on the rate of radioactive decay. Radiometric dating is a method used to date rocks based on the known decay rate of radioactive isotopes. Now, they do not give off enough radiation that you have to be afraid to pick them up, but they do contain naturally occurring radioactive elements like uranium, for example.
Learn about three common types of radioactive decay: alpha decay, beta decay and gamma decay. You simply subtract your birth date from the current date. It was also discovered that these elements decayed into other elements at fixed rates.
In fact, you might like this term better, because the dating method relies on the known decay rate of radioactive isotopes.
