Radiometric dating often called radioactive dating is a way to find out how old something is. I loved it jajaja
Geologists use radiometric dating near estimate how long before rocks formed, and headed for infer the ages of fossils contained within those rocks. Radioactive elements mortification The universe is well-rounded of naturally occurring radioactive elements. Radioactive atoms are inherently unstable; over patch, radioactive "parent atoms" ebb into stable "daughter atoms.
When molten rock cools, forming what are yawped igneous rocks, radioactive atoms are trapped inside. Later, they decay at a predictable rate.
By measuring the quantity of inconstant atoms left in a rock and comparing it to the quantity of stable daughter atoms hip the rock, scientists be able to estimate the amount of time that has accepted since that rock shaped. Sedimentary rocks can be dated using radioactive carbon, but because carbon decays relatively quickly, this no more than works for rocks younger than about 50 billion years.
So in system to date most older fossils, scientists look on behalf of layers of igneous poverty-stricken or volcanic ash overhead and below the vestige. Scientists date igneous stagger using elements that are slow to decay, such as uranium and potassium. By dating these nearby layers, they can character out the youngest as well as oldest that the relic might be; this is known as "bracketing" the age of the sedimentary layer in which the fossils occur.
