What are index fossils and how are they used to determine the absolute age of sedimentary rock?
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.
How do scientists use sedimentary rock to determine a fossils relative age?
Scientists can use sedimentary rock to determine a fossil's relative age by examining the layers in which the fossil is found. The principle of superposition states that in an undisturbed sequence of sedimentary rock layers, the oldest layer is at the bottom and the youngest layer is at the top. By identifying the layer in which the fossil is located, scientists can approximate its relative age compared to other fossils and rock layers.
What are 3 examples that apply to both relative dating and absolute dating?
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.
By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers scientists can learn what?
By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers, scientists can learn about the relative ages of the fossils. This helps in understanding the sequence of events in Earth's history and the evolutionary relationships between different species.
How is the absolute age of the fossil different from the relative age?
The absolute age of a fossil provides a specific numerical age in years, usually determined through radiometric dating techniques. Relative age, on the other hand, only allows us to determine the fossil's age in relation to other fossils or rocks, based on their layering or sequence in the rock record.
What are index fossils and how are they used to determine the absolute age of sedimentary rock?

Fossils that can be used to establish relative dates are most likely to be found in?
Sedimentary rocks, which form in layers over time, are most likely to contain fossils that can be used to establish relative dates. Fossils found in these rocks provide a record of the organisms that lived at specific times in Earth's history, allowing scientists to determine the relative age of the rock layers.
How do scientists use sedimentary rock to determine a fossils relative age?
Scientists can use sedimentary rock to determine a fossil's relative age by examining the layers in which the fossil is found. The principle of superposition states that in an undisturbed sequence of sedimentary rock layers, the oldest layer is at the bottom and the youngest layer is at the top. By identifying the layer in which the fossil is located, scientists can approximate its relative age compared to other fossils and rock layers.
True or False Fossils may be dated by either the relative dating method which determines the relative order of fossils or by the absolute dating method which uses radioactive isotopes?
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.
Can fossils be used to determine the relative ages of rocks 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.
Do index fossils tell the relative or absolute age of fossils?
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.

Absolute dating is best performed on rocks formed?
Absolute dating is best performed on igneous rocks formed from volcanic activity, as they contain radioactive elements that decay at a known rate and can be used to determine the rock's age. Sedimentary rocks are typically dated using the fossils contained within them, allowing for a relative dating technique rather than absolute dating.
By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers scientists can learn what?
By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers, scientists can learn about the relative ages of the fossils. This helps in understanding the sequence of events in Earth's history and the evolutionary relationships between different species.
