Because if you know how old the fossil is, and you find the fossil inside a rock, you know that rock has a maxium age corresponding with the age of the fossil.

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 kind of rock layers did index fossil date?
index fossils are used to date the rock layers they are found incc
What are index fossils and how are they used to determine the absolute age of sedimentary rocks?
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.
Fossils that appear all over the world in certain rock layers are what?
Fossils that appear all over the world in particular rock layers are called index fossils. These fossils are used by scientists to correlate and date rock layers in different locations, providing insights into the Earth's geological history and past environments.
How can fossils be used to date the rock in the strata?
Because index fossils are useful because they tell the relative ages of the rock layers in which they occur. They also tell what year they were made.
What is a fossil used to date surrounding rock layers called?
A fossil used to date surrounding rock layers is called a index fossil. Index fossils are particularly useful for determining the relative ages of rock layers in different locations.
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.
Explain how an index fossil can be used date rock.?
Index fossils are fossils of organisms that lived for a relatively short period of time but were widespread geographically. By identifying these index fossils in a particular layer of rock, scientists can determine the age of the rock and correlate it with other rock layers containing the same index fossils. This allows for the relative dating of rock layers based on the presence of specific index fossils.
How index fossils can be used to determine the age of rocks?
Index fossils are used to date rocks by correlating the fossils found in the rock layers with known ages of those fossils. Index fossils are distinctive, widespread, and lived for a relatively short period of time. By identifying these fossils in a rock layer, scientists can infer the age of the rock based on the age range of the known fossil.
What kind of rock layers did index fossil date?
index fossils are used to date the rock layers they are found incc

Fossils that appear all over the world in particular rock layers are called index fossils. These fossils are used by scientists to correlate and date rock layers in different locations, providing insights into the Earth's geological history and past environments.
How can fossils be used to date rocks?
Geologists look for index fossils in the sedimentary rock to help determine its age. Index fossils are of organisms that were widespread and only existed during a specific slice of geologic time. Finding an index fossil in a rock means that the rock dates to that specific slice of time.
How can fossils be used to date the rock in the strata?
Because index fossils are useful because they tell the relative ages of the rock layers in which they occur. They also tell what year they were made.

Why are index fossils useful for figure out the age of a set of disturbed rock layers?
index fossils are useful for figuring out the age of a set of disturbed rock layers by index fossils are used to determine when rock layers were formed so if they were used to figure out the age of a set of disturbed rock layers than they can also figure out when they were formed .
