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.
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.
Is the sedimentary rock strong?
That depends on the rock. Some sedimentary rocks are used as construction material, or as raw material for different kinds of industries. Older sedimentary rocks have a scientific value as well, as ages of fossils can be determined by studying them.
What can be used to date fossils in rocks to give an approximate age.?
The study of strata is called stratigraphy. Stratigraphy can be used to determine an approximate age of fossils in rocks.
How do you see a sedimentary rocks age by looking at the fossils?
The age of sedimentary rocks can be estimated by identifying the fossils they contain and comparing them to known fossil sequences. Fossils can be used as index fossils, which are species that existed for a relatively short period of time, helping to narrow down the age range of the rock layer they are found in. By matching the fossil assemblage to a known time period in the geologic timescale, scientists can determine the approximate age of the sedimentary rock.

What are index fossils and how are they used to determine the absolute age of sedimentary rock?
Index fossils are fossils of organisms that lived for a relatively short period and had a wide geographic distribution. By identifying these fossils in sedimentary rock layers, scientists can determine the relative age of the rock based on the known age range of the index fossil. Absolute age dating techniques, such as radiometric dating of igneous rocks that bracket the sedimentary layers containing the index fossils, are then used to determine the exact age of the sedimentary rock.
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.
Why have sedimentary rocks been very important to scientists who study how living things have changed over the ages?
The vast majority of fossils are found in sedimentary rocks. Fossils are they key to understanding what living things used to be like.

How are sedimentary rock layers used be scientists to learn about the past?
plant and animal fossils are most often found in layers of sedimentary rocks

What type of rock is most useful historical geologists?
Sedimentary rocks are most useful for historical geologists because they can contain fossils and provide information about past environments and the Earth's history. Sedimentary rocks also often preserve layers that can be used to determine the relative age of rock formations.
What is the type of rock that is used to determine how old the earth is and what lived on it?
The Answer is Sedimentary Rocks
