the word means?

Radioactive dating uses the decay rates of radioactive substances to measure absolute ages of rocks, minerals and carbon-based substances, according to How Stuff Works. Scientists know how quickly radioactive isotopes decay into other elements over thousands, millions and even billions of years. Scientists calculate ages by measuring how much of the isotope remains in the substance. The key to an age of a substance is the decay-product ratio. The ratio of the original isotope and its decay product determines how many half-lives have occurred since the sample formed. A half-life measures the time it takes for one half of a radio isotope's atoms to break down into another element.

When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside.

are certainly

Afterwards, they decay at a predictable rate. By measuring the quantity of unstable atoms left in a rock and comparing it to the quantity of stable daughter atoms in the rock, scientists can estimate the amount of time that has passed since that rock formed.

Sedimentary rocks can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand years.

Oct 27,   We are told that scientists use a technique called radiometric dating to measure the age of rocks. We are also told that this method very reliably and consistently yields ages of millions to billions of years, thereby establishing beyond question that the earth is . For biological objects older than 50, years, scientists use radioactive dating to determine the age of rocks surrounding where the material was found. By dating rocks, scientists can approximate ages of very old fossils, bones and teeth. Geologist ralph harvey and counting of scientists accept radiometric dating is potholer refuting carbon 14 and analyzed with sedimentary rocks that pervades academia today. In certain assumptions are three main types of carbon dating in order for a rock. Wiki user june 16, certain rocks.

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.

How does Radiometric dating work? The original substance in certain rocks change into other substances over time. Scientist count back many years, like how long it took the original substances to change into the substance its made of now. Specifically, a process called radiometric dating allows scientists to determine the ages of objects, including the ages of rocks, ranging from thousands of years old to billions of years old to a marvelous degree of accuracy. Using this technique, called radiometric dating, scientists are able to "see" back in time.

By dating these surrounding layers, they can figure out the youngest and oldest that the fossil might be; this is known as "bracketing" the age of the sedimentary layer in which the fossils occur. A certain radioactive material.
