No. To find the relative age of a rock, you need to identify the geologic age, the relative time in Earth's history that the rock was formed. This can be done by physical identification of any corresponding index fossil evidence in the rock, or by identifying it with a geological event or rock formation that has been previously been dated.

What process involves the comparison of rock layers with others in a sequence to determine its age?
Relative dating involves comparing rock layers with others in a sequence to determine their ages. This process relies on the principle of superposition, where younger rocks are usually found on top of older rocks. By studying the relationships between different rock layers, scientists can establish the relative ages of the rocks.
What do geologists use to determine the relative ages of a rock?
Relative dating refers to the process of determining the age of a rock, feature, or fossil by comparing it to the rocks around it. To use relative dating, you need to look at the order each rock layer was deposited.
What law do scientists apply to determine relative ages of rocks when the find faults or intrusions?
Scientists use the principle of cross-cutting relationships to determine the relative ages of rocks when they find faults or intrusions. This principle states that the rock being cut must be older than the geological event cutting through it (like a fault or intrusion). By analyzing the sequence of events and their relative ages, scientists can piece together the geological history of a region.
What are other principles of relative age dating do geologists use to analyze the ages of rock?
In addition to the principle of superposition, geologists also use the principles of original horizontality, cross-cutting relationships, and inclusions to analyze the ages of rock layers. The principle of original horizontality states that sedimentary rocks are originally deposited in horizontal layers. Cross-cutting relationships help determine the sequence of events by noting which rock layers are cut by or intrude into others. Inclusions are rock fragments within another rock unit that must be older than the rock containing them. By applying these principles, geologists can determine the relative ages of rock layers and the sequence of geological events.
What is an older rock lie under younger rock mean?
This principle is known as the law of superposition, which states that in undisturbed layers of rock, the oldest rocks are found at the bottom and the youngest rocks are found at the top. Essentially, it is a key concept used in relative dating to determine the relative ages of rock layers.
How can fossills be used to determine the relative ages of rock layers?
fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.

Is it true that Stratigraphy is a method to determine the relative age of rock strata?
Yes, that is true. Stratigraphy is the study of rock layers (strata) and their relative positions in order to determine the sequence of events that created them. By analyzing the different layers and the fossils or artifacts found within them, scientists can establish the relative ages of the rock strata.
Which is an example of relative dating?
One example of relative dating is studying the layers of rock in a particular area. By analyzing the sequence of rock layers and the fossils within them, scientists can determine the relative ages of the rocks and the fossils they contain.
How can fossils be used to determine the relative ages of rock?
If we know the age the respective organism is known to have occupied a certain region in the geologic past we can then correlate that to the rock its fossil was found in and consequently deduce the rock's relative age.
Fossil used to compare the relative ages of fossils?
Index fossils are used to compare the relative ages of fossils. These are fossils that are known to have lived during a specific time period, helping to date the rock layers in which they are found. By identifying and comparing index fossils, scientists can determine the relative ages of different rock layers and fossils.
What are relative fossils?
Answer: The age of a rock compared to the ages of the rock layers.
IS stratigraphy is a method to determine the relative age of rock strata?
Yes, stratigraphy is a method used to determine the relative age of rock strata by studying the layers or strata of rock and determining their relative ages based on principles of superposition and original horizontality. This method helps geologists understand the sequence of events that have occurred in a particular area over time.
Is stratigraphy a method to determine the relative age of rock stata?
Yes, stratigraphy is a method used to determine the relative ages of rock layers or strata by studying their sequence, thickness, and composition. The principle of superposition states that in an undisturbed sequence of rock layers, the oldest rocks are at the bottom while the youngest are at the top.
