In which layer of rock shown below are the fossils the youngest?

The fossils are typically found in the uppermost layer of rock, as sedimentary rock is formed from the accumulation of materials over time. Newer layers are deposited on top of older layers, meaning that the youngest fossils would be located in the most recent (top) strata. Therefore, the youngest fossils are in the layer that is highest in the sequence shown.


What is the relative age of fossils found at the top layer of rock?

They are called index fossils, fossils of organisms that were widespread, evolving quickly, and only appeared in the geologic column for a specific length of time.


Which of the following is most accurate in helping pinpoint a time period on the geologic time scale during which a rock layer was formed?

Fossils found in the rock layer are the most accurate method for pinpointing a time period on the geologic time scale. By identifying the specific types of fossils present, scientists can determine the age of the rock layer relative to the known age ranges of those fossils.


How could geologists use fossil in rock layer B to date a rock layer in another location?

Geologists can use index fossils from rock layer B to correlate the age of the rocks in another location by matching the presence of these unique fossils. Index fossils are widely distributed and lived for a short period of time, making them useful for dating rock layers. By identifying the same index fossils in both rock layers, geologists can infer that they are of similar age.


What fossils can be formed from plant leaves a thin layer of carbon on rock?

A fossil fuel

What statements states relative age?

"The fossils found in this rock layer are older than the fossils found in the layer above it." "The granite intrusion is younger than the surrounding sedimentary rocks." "The volcanic ash layer is slightly older than the layer of soil above it." "The erosion pattern on the hillside indicates that the granite rocks are older than the layers of sediment deposited on top of them." "The cross-cutting relationship between the fault and the layers of rock indicate that the fault is younger than the rock layers it cuts through."


Why are index fossils so important to geologists?

Index fossils are very important to geologists because they identify geological time periods. Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.
