What is the relative age of layer 3 hint With what absolute ages can you compare it?
To determine the relative age of layer 3, you would compare it to the layers above and below it. If, for example, layer 2 is above layer 3 and layer 4 is below, layer 3 is older than layer 2 but younger than layer 4. You could also compare it to known absolute ages of surrounding layers if they have been dated, such as layer 2 having an absolute age of 150 million years and layer 4 being 200 million years old. This context helps establish layer 3's relative age within the geological time scale.

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 fossil used to compare the relative ages of fossils?
An index fossil. An index fossil's age is known, allowing scientists to know the relative age of other fossils based on their position relative to the index fossil. (Ex. If a fossil is deeper in the earth, it is older than the index fossil)
Can geologists use radioactive dating to find the absolute ages of sedimentary layer A B C D and E?
yes because its a rock
How are the laws of superposition and crosscutting relationship used to determine the relative age of rocks?
They are used to determine the relative ages of rocks by stating that younger rocks lie above older rocks, and that rocks that cut through a layer are younger than the existing layer.
Why are the relative and absolute ages so important to a scientist in geology?
It is quicker and can be done in the field for a quick age referencing of a rock sample.
What two types of ages of rocks that geologists talk about?
Geologists talk about relative ages and absolute ages of rocks. Relative ages are determined by the order of rock layers, with younger layers on top and older layers at the bottom. Absolute ages are determined through radiometric dating methods to provide a specific age in years for a rock sample.
What is the age of an object in relation to the ages of other objects called?
Relative age.
How is earths geolgic history determined?
it is determined by studying the relative and absolute ages of rocks and fossils
Main differences between relative dating and absolute dating?
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.
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.

How can the relative and absolute ages of rock be determined?
By comparing the relative percentages of a radioactive (parent) isotope and a stable (daughter) isotope.
How does relative dating and absolute dating help scientists assemble a fossil record for an area?
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.
What does relative dating mean in biology?
Relative dating in biology refers to estimating the age of a fossil or rock layer based on its position relative to other fossils or rock layers. It does not provide an exact age, but rather an estimation of the order of events. This method relies on principles like superposition and stratigraphy to determine the relative age of different geological features.
To compare the relative ages of fossils scientists sometimes use an easily recognized species called?
To compare the relative ages of fossils, scientists use an early recognized species called an index fossil. An index fossil must have existed for a short period time and must have covered a wide geographical range.
