Why are radioactive isotopes and half life important to science?
Radioactive isotopes are important because they can be used as tracers in medicine and industry, and in dating rocks and fossils. The concept of half-life is important because it allows scientists to predict how long it will take for a radioactive material to decay to half its original amount, which is crucial for understanding processes like nuclear decay and radioactive dating.
Can use radiometric dating on all minerals to tell their absolute age?
You can't date all minerals using the radiometric dating method because not all minerals have radioactive isotopes. In addition, the parent and daughter isotopes must remain together in a rock to use them to determine the rock's age. Because sedimentary rocks contain fragments of many rocks that could be different ages, radiometric dating is less useful for dating sedimentary rock. This technique is primarily used to date igneous rocks.
How can radioactive decay tell how old something is?
Radioactive decay can determine the age of an object through a process called radiometric dating. This method measures the concentration of radioactive isotopes and their stable decay products in a sample. By knowing the half-life of the isotope, which is the time it takes for half of the original radioactive material to decay, scientists can calculate the time that has elapsed since the object was formed. This technique is commonly used in dating ancient rocks, fossils, and archaeological finds.
A technique used in absolute dating?
Method of determining the age of a mineral that utilizes the damage done by the spontaneous fission of uranium-238, the most abundant isotope of uranium. In geology and archaeology, the process of determining an object's or event's place within a chronological scheme.
Are scientists able to determine rock ages in specific years?
Scientists can estimate the age of rocks using various methods such as radiometric dating, which measures the decay of radioactive isotopes in the rocks. These techniques can provide an estimate of the age of a rock in millions to billions of years rather than specific years. Determining an exact age in specific years is not usually possible due to the limitations of the dating methods.

How do you tell how old a fossil is by the rock layer?
You can determine the relative age of a fossil by looking at the position of the fossil in the rock layers. The closer a fossil is to the surface, the younger it is relative to fossils found deeper in the layers. To determine the absolute age of a fossil, scientists use radiometric dating techniques on the surrounding rocks to determine the age of the rock layer the fossil is found in.
How is radioactive decay useful in dating rocks and minerals?
Radioactive decay has a constant rate of change, therefore it con be used to somewhat accurately tell the age of an object if you work backwards through the use of half-lifes (half of the existing radioactive material decays, leaving half of the original in its original form)

Does radioactive dating allow us to find relative or absolute age?
Absolute dating of rock is achieved by radiometric dating techniques. Relative dating is achieved by determining the position of rock in strata, and the appearance of certain index fossils. Relative dating was a precursor to absolute dating. Before absolute dating techniques were discovered, the age of a rock was a guesstimate at best. Radioactive dating allows us to find an approximate date. So if something is dated about a thousand years ago plus or minus a hundred years the object may be from sometime between 1,000 and 1,200 A.D.
What is realative dating?
i think that realitive dating is dating in real life and not online... please tell me if im wrong well that is 100% wrong.....relative dating is to do with the dating of fossils.....

What does radiometric dating tell geologist about some rocks and minerals?
their ages
What is the methods that tells you which layer of rock is oldest but does not tell you exactly how old?
Relative dating
What is the difference between relative dating and numerical?
Numerical dating is when you are trying to determine how long ago something took place or specifically how old something or someone is. For example, the extinction of the dinosaurs about 65 million years ago. Relative dating cannot tell us how long ago something took place, only that is followed one event and preceded another.
How can fossils be used to determine the relative ages?
They are able to tell the order in which events occured, NOT how long ago they occured.Identify the order in whicih rock units formed(:rocks makes babys with apenis
