Fossils may be absent in layers c and e due to several factors, such as environmental conditions that were not conducive to fossilization, like high levels of erosion or sediment displacement. Additionally, these layers might represent periods of time when no organisms existed, or when existing organisms did not have the right conditions for preservation. It's also possible that the layers were subjected to geological processes that destroyed any fossils that may have existed.

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.
Why are the oldest fossils sometimes not on the bottom layers of rocks?
Older fossils may not always be found at the bottom layers of rocks due to geological processes like folding, faulting, or erosion, which can disrupt the original order. In these cases, older fossils may be found at higher layers while younger fossils are found in lower layers.
Fossils that appear all over the world in certain rock layers are what?
Fossils that appear all over the world in particular rock layers are called index fossils. These fossils are used by scientists to correlate and date rock layers in different locations, providing insights into the Earth's geological history and past environments.

How does the position of fossils in layers show evolutionary changes?
Assuming the layers aren't deformed, the lowest deposition layers are the earliest. Later deposition layers accumulate on top of the earlier layers. Thus, the lowest layers have the earliest fossils, and the highest layers have newer fossils. By comparing the features of early and late fossils of a species, you can determine some of its evolutionary changes. Of course, not all features survive in a fossil - soft tissues, for example.

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 does the law of superstition date fossils?
The law of superstition, also known as the law of superposition, states that in undisturbed sedimentary rock layers, older layers are found below younger layers. This principle helps paleontologists date fossils by examining their positions within these layers. If a fossil is found in a lower layer, it is considered older than fossils found in higher layers. Thus, the relative age of fossils can be determined based on their stratigraphic context.
Most fossils are found in what A in rock layers which formed underwater b in rocks which were formed from cooling lava from volcanoes c in sand on seashores d in the waters of seas and lakes?
A. in rock layers which formed underwater
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.
What could you say about the age of fossils from layer E?
The age of fossils from layer E can be determined through various dating methods, including radiometric dating and stratigraphic correlation with other layers. Typically, the position of layer E within the geological strata can provide insights into its relative age compared to adjacent layers. If layer E contains specific fossil types that are known to have existed during particular geological periods, this can also help estimate its age. Overall, a combination of these methods would yield a more accurate understanding of the age of the fossils in layer E.
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.
