Radiometric age dating

Rated 4.64/5 based on 836 customer reviews

So in order to date most older fossils, scientists look for layers of igneous rock or volcanic ash above and below the fossil.

Scientists date igneous rock using elements that are slow to decay, such as uranium and potassium.

Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.
