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.
What was the first type of armor used in the middle ages?
it was chainmail
How do you dig up fossils on Pokemon platinum?
Go Underground used the Explorer Kit. There is a man in-game who teaches you all about Underground. You get the fossils by mining them out and awaken them by going to the town with the first gym
What is Often used to determine the distance to nearby stars?
parallax
What song is used in the Outcasts trailer?
took me ages to find it but its (Foals - Spanish Sahara) :)
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.

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)
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.
What are index fossils used to determine?
Index fossils are used to determine the relative age of rock layers. By studying the presence of these distinct fossils in different layers of rock, geologists can identify the relative age of the rocks and correlate them with other rock layers in different locations.
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.
How can you use fossils and geologic features interpret the relative age of rock layers?
Fossils can be used to determine the relative age of rock layers by comparing the types of fossils found in different layers. Fossils of organisms that existed for a short period of time can be used to date layers of rock containing them. Geologic features such as fault lines and unconformities can also help determine the relative age of rock layers by showing where layers have been disturbed or eroded.
How do fossils in rock layers help scientists identify the age of rocks?
Fossils in rock layers can be used for relative dating, where older fossils are found in lower layers and younger fossils in higher layers. By comparing the fossils in different layers to known fossil sequences, scientists can estimate the age of the rocks. Fossils provide a timeline of life on Earth and can help determine the relative ages of rock layers.
How fossils can be used to determine the absolute and relative age of a sedimentary rock layer?
Perhaps by carbon dating and by comparing with the evolution and dominance of various organisms in the geological time scale.
What do paleontologists use to determine age of rocks?
Paleontologists use fossils to determine the relative ages of rocks. Due to evolution the fossil assemblage in rocks changes over time and the different assemblages can therfore be used to place the rocks in which an assemblage is found in its place in the evolutionary sequence.
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.
