   ♥♥♥ Link: Difference between relative and absolute dating fossils

   Example: Fossil is anywhere from 5,000 to 8,000 years old. That is, scientists cannot tell exactly how old the layers are in years to the present date, only which is older than the other. Geologists also difference between relative and absolute dating fossils radiometric methods for absolute dating based on radioactive decay of certain elements. For a determination in the field, geologists attempt to date a rock or fossil based on its relative age, which is usually determined by the presence of a trace fossil, or daitng position of the rock layer in relation to a layer of rock with a known age. However, carbon dating is an absolute dating technique fosssils can give an estimate of the actual age of an artifact and thus an estimate of the age of other objects in the same layer. Similarly, relative dating is done by paleontologists who find layers of fossils. The age is based on the half-life of the isotopes their rate of decay absoluye time. However while you can form a time sequence using this method you can not pin any one point in the sequence down to an actual number of years ago. However, there are clonal trees that have lived longer, as wel. The radiometric techniques that give absolute dating estimates are based on radioactive decay of elements such as uranium. Example: You are 16 years old. Interests: Earth and planetary sciences, rock and mineral collecting. Relative dating observes the placement of fossils rating rock in layers known as strata. The differences between relative and absolute age of rock layers is that relative age only shows that a rock is older or younger and doesn't give the absolute age. Similarly for paleontologists who find layers of fossils. Relative dating uses observation of location within rock layers, while radiometric dating uses data from the decay of radioactive substances within an object. The difference between relative dating and absolute dating is that relative dating is a method of sequencing events in the order in which they happened. Similarly for paleontologists who find layers of fossils. Relative dating observes the placement of fossils and rock in layers known as strata. This is "relative dating", but it doesn't give you an exact age. Radiometric dating, based on known rates of decay of radioactive isotopes in objects, allows a specific age of an object to be determined to some degree of accuracy. Radiometric dating, or numeric dating, determines an actual or approximate age of an object by studying the rflative of decay of radioactive isotopes, such as uranium, potassium, rubidium and carbon-14 within that object. Looking at how rock formations are structured, a geologist may be able to say which rock eelative developed in which layer in a particular order but not be able to determine that actual geologic age of the layers. For geologists, it is similar.
