How do the fossils in rock layers help scientists identify the age of the rock?
well the fossils are trace fossils so we are gonna have too go with trace fossils cause it seems like it knows were it is located the print and the hard rock that has been some places for millions and millions of years.
What information do fossils provide about the history of life?
Fossils can help us learn about what happened in the past, what is currently happening in the present, and what will happen in the future. The Earth is always changing, nothing on its surface is truly permanent. Rocks that are now on top of a mountain may have been at the bottom of a sea once. We can dig up fossils anywhere! From the fossil, we can determine what organisms were living, the habitat, the climate, and compare with other fossils to see the many changes and differences. Fossils are very beneficial to our Earth's history. :D
Why are fossils important to evolution?
Fossils give a record as to what organisms lived throughout different time periods. Generally speaking, the lower layers of soil show the oldest fossils, which aids scientists in following the progression of evolution of an organism. Also, radioactive carbon dating is used in dating how old a fossil is by finding the amount of carbon^14, and then calculating how many half lives have passed to reach this amount.
Why are fossils so important?
Fossils are important to the humans because they help us learn about animals that are extinct (like dinosours). They can also help us with many clues as to how dinosours became extinct, and what they looked like.
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.
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 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 do fossil records provide evidence for environmental change?

What can geologist learn from fossils?
Geologists can learn about the Earth's history, past environments, and changes in climate by studying fossils. Fossils provide evidence of how life has evolved over time and can help geologists understand the geological processes that have shaped the planet. They also help in dating rocks and determining the age of different geological formations.
How fossil records help in solving problems about evolutions?
When it comes to fossil records, all of the fossils of one geological era are contained in one strata (Layer) of rock. The fossil record does not only contain animal fossils. It also contains fossils of the different flora of the region, thus dictating the type of environment. If you know what kind of environment was around then you will know what type of skills a species of animal would need to survive. Therefore as you look through newer layers you can see how a certain species have changed over time to adapt to their environment.
What are the fallacies of fossil dating?
One of the biggest fallacies of fossil dating is that they use the rock layer to help determine the age of the fossils, but the fossils are also used to help determine the age of the rock layer.
How do the fossils in rock layers help scientists identify the age of the rock?
well the fossils are trace fossils so we are gonna have too go with trace fossils cause it seems like it knows were it is located the print and the hard rock that has been some places for millions and millions of years.
How does erosion help in bringing fossils to the earths surface?
erosion helps bring fossils to earths surface by when a animal dies it turns into a fossil
What are the three criteria that must be met in order for a fossil to be considered an index fossil?
Index fossils must be abundant in the rock record, have a wide geographic distribution, and have a short time range in which they existed. These criteria help geologists correlate and date different rock layers.
Which word means the remains or imprints of once-living organisms found in layers or rock?
The word you are looking for is "fossil." Fossils are the preserved remains or traces of organisms that lived in the past, typically found in sedimentary rock layers. These remains provide valuable information about the history of life on Earth and can help scientists understand evolutionary processes.
How does determining the ages of igneous rocks help to date fossils?
Determining the ages of igneous rocks helps to establish the age of the rock layer in which fossils are found. By dating the igneous rocks above and below the fossil-containing layer, scientists can narrow down the possible age range of the fossils found within that layer. This helps to provide a more accurate estimate of the fossil's age.
I found a fossil and don't know what it is?
It is best to consult a geologist or archaeologist to help you identify unknown fossils.
