|
Relative dating provides the exact age of a rock, while absolute dating provides a rough estimate of the rock’s age
|
|
|
Relative dating can estimate a rock’s age only in relation to other objects or events, while absolute dating can provide an actual age
|
|
|
Relative dating uses several types of radioactive decay to determine an object’s relative age, while absolute dating only uses the halflife of uranium 235
|
|
|
Relative dating and absolute dating can only determine the rock’s age in relation to other objects or events

Detailed explanation-1: -Relative dating does not offer specific dates, it simply allows to determine if one artifact, fossil, or stratigraphic layer is older than another. Absolute dating methods provide more specific origin dates and time ranges, such as an age range in years.
Detailed explanation-2: -Relative age is the age of a rock layer (or the fossils it contains) compared to other layers. It can be determined by looking at the position of rock layers. Absolute age is the numeric age of a layer of rocks or fossils. Absolute age can be determined by using radiometric dating.
Detailed explanation-3: -Relative dating places events or rocks in their chronologic sequence or order of occurrence. Absolute dating places events or rocks at a specific time. If a geologist claims to be younger than his or her co-worker, that is a relative age. If a geologist claims to be 45 years old, that is an absolute age.
Detailed explanation-4: -There are two methods of determining the ages of rocks: relative dating and absolute dating. Relative dating is a method of arranging geological events based on the rock sequence.
Detailed explanation-5: -Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy (layers of rock are called strata). Relative dating does not provide actual numerical dates for the rocks.
