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. Absolute dating is a method of estimating the age of a rock sample in years via radiometric techniques.
Short Answer:
The term relative dating is distinguished from absolute dating to make it clear that one does not get a specific estimate of the age of an object from relative dating, but one does get such an estimate of true age from absolute dating. There are several techniques employed in both sets of methods. Radiometric dating is one type of absolute dating.
Long Answer:
Sciences such as geology, Paleontology and archeology are very interested in identifying the age of objects found and these scientists sometimes use both relative dating or absolute dating to characterize the age of the objects they study.
Before radiometric dating (or other methods of absolute dating like counting tree rings) it was difficult to determine the actual age of an object. 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.
Relative dating is a scientific process of evaluation used to determine the relative order of past events, but does not determine the absolute age of an object. The circumstances of the object may allow one to say that one object is older than another without being able to assign a particular age to the objects. Very often historical evidence is found in layers and older layers are further down that the top layers.
For example:
If an archaeologist is studying past civilizations, the archaeologist may be able to say that in a particular location the ruins of one civilization were found to have been built on another and so the layers unearthed in an excavation convey the sequence of historical occupations without revealing the actual dates. However, carbon dating is an absolute dating technique that 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. Carbon dating is one example of radiometric dating.
Similarly, relative dating is done by paleontologists who find layers of fossils. By deducing which fossils are formed in the sequence of time, the periods when the particular fossilized entities existed can be arranged in order without the actual dates of when the fossils were laid down. The radiometric techniques that give absolute dating estimates are based on radioactive decay of elements such as uranium.
For geologists, it is similar. Looking at how rock formations are structured, a geologist may be able to say which rock was developed in which layer in a particular order but not be able to determine that actual geologic age of the layers. Geologists also have radiometric methods for absolute dating based on radioactive decay of certain elements.
information is providedv by absolute that cannot be provided by relative dating?
Radioactive dating techniques, such as radiocarbon dating or uranium-lead dating, provide an absolute age for rocks by measuring the decay of radioactive isotopes within them. This helps determine the actual age of rocks rather than their relative age.
relative and absolute. relative is determining the relative order of past events, without necessarily determining their absolute age. Absolute is the process of determining an approximate computed age in archaeology and geology.
True. Fossils can be dated using both relative dating methods, which determine the sequence of events in which fossils occurred, and absolute dating methods, which rely on radioactive isotopes to calculate the age of fossils.
Relative dating is not more accurate than absolute dating. Relative dating will, if done properly, give you an order sequence in time but it will not return any information about when something happened unless there is other information that can be used to establish a time frame.

Relative dating says that something happened a certain amount of years after something else happened. Or before. Absolute dating says that something happened in a certain year. (Month, day . . .)
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
both have methods of descovering the age of an object or event.
Relative dating is the science determining the relative order of past events, without necessarily determining their absolute age Absolute dating is the process of determining an approximate computed age in archaeology and geology.
Relative dating determines the age of a rock layer or fossil by comparing it to other layers, while absolute dating provides a specific age in years. Relative dating relies on stratigraphy and the Law of Superposition, while absolute dating uses techniques like radiometric dating to provide numerical ages. Both methods are used in combination to establish a more accurate timeline of Earth's history.
Absolute age dating defines an exact date -1875. Relative dating gives a relative answer -10 years after the end of the civil war. Your welcome for helping you with Biology Homework.... *Cheaters* Geology homework. Actually. -.- Jeesh, people these days.

Law of Superposition: In both relative and absolute dating, the principle of superposition is applied to determine the sequence of events. It states that in an undisturbed sequence of rock layers, the oldest layer is at the bottom. Fossil succession: Both relative and absolute dating methods use the principle of fossil succession to help determine the age of rock layers. By comparing the types of fossils found in different layers, scientists can infer the relative or absolute age of the rocks. Index fossils: Index fossils are commonly used in both relative and absolute dating. These fossils are distinct, widespread, and existed for a relatively short period of time, making them useful for correlating and dating rock layers.
Radioactive dating techniques, such as radiocarbon dating or uranium-lead dating, provide an absolute age for rocks by measuring the decay of radioactive isotopes within them. This helps determine the actual age of rocks rather than their relative age.
No. Absolute dating is the most precise method for dating rock. Absolute dating relies on the known rate of decay of radioactive elements present in the rock to arrive at a fairly precise age.
