Is A scientist who researches the age of rock layers in the Grand Canyon studies earth science?
Earth
How do fossils in rock layers help scientists identify the age of rocks?
depending on how deep the rock is in the ground tells scientists how old the rock is
How the relative age of a fossil is determined by studying layers of rock?
It is determined because in layers of rocks the fossils are found so the layers of rocks give information to the scientist about the age of a fossil so like that the relative age of a fossil is determined.
A fossil that is found in the rock layers of only one geologic age and that is used to establish the age of the rock layers?
An index fossil.
Why are index fossils useful for figure out the age of a set of disturbed rock layers?
index fossils are useful for figuring out the age of a set of disturbed rock layers by index fossils are used to determine when rock layers were formed so if they were used to figure out the age of a set of disturbed rock layers than they can also figure out when they were formed .
What are relative fossils?
Answer: The age of a rock compared to the ages of the rock layers.
How do scientists use sedimentary rock to determine a fossils relative age?
Scientists use sedimentary rock to determine a fossil relative age by studying the rock.
How do scientist age a rock?
Tehy just do
How can you use fossils and geologic features interpret the relative age of rock layers?
Geologists use carbon-14 to interpret the relative age of rock layers
How are the layers of rock if they are undisturbed?
The undisturbed rock layers are horizontal and in order of age from youngest nearest the surface to oldest at the bottom of the rock unit.
What is the difference between the relative age and absolute age of rocks?
Relative age is the age of a rock relative to the rock layers around it, absolute age is a rock's exact age.
How do scientists determine history by using fossils and sedimentary layers?
Geologists and paleontologists look for index fossils in rock strata. These index fossils appear only in rocks of a certain age. Finding them lets the scientist know the approximate age range of a rock formation. Layers of sedimentary rock will also aid the scientist is determining the climate from that age, of any volcanism that may have taken place, the lifeforms that existed, and even find evidence of catastrophic events such as asteroid collisions that may have led to extinction events.
