What does relative dating provide for the age of a rock layer or fossil?
estimate
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 can you find the age of a layer of rock that is surrounded by layers of volcanic ash?
Use PEMDAS
Which of these provides the best estimate of how long it took a thick layer of sedimentary rock to form?
Calculating the age of the top and bottom of the layer
What is the best indication of a relative age of a rock layer?
The position of the layer compared to other layers.
How does the age of a rock layer compare with an igneous intrusion that is through it or an igneous rock extrusion above it?
If it is above it, the rock layer came after the intrusion. if the intrusion went through the rock layer is older because they layer had to be there in order for the intrusion to go through.
A scientist identifies a variety of fossils in a layer of sedimentary rock By applying the principle of fossil succession the scientist can identify?
The age of the rock layer
The age of a rock compared to the age of other layer is called?
wats good people

how can index foslies help determin the age of the rock layer?
they cant
Does the law of superposition helps geologist determine the absoloute age of a rock layer?
no, the relative age
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.
What is the true age of a rock or fossil?
The method used will be determined by the rock type, but the age of a rock will be determined by a determination of the amount of decay of a radioactive isotope, either contained in the rock, or in a geologic layer of rock coinciding with a fossil.
What describes the characteristics of the Earth's mantle?
C.) the thickest layer of hot rock
Why is the C horizon the least evolved layer of soil?
The C horizon contains only party weathered rock.
How can you use fossils and geologic-features interpret the relative age of rock layer?
Geologists use carbon-14 to interpret the relative age of rock layers
Which layer of soil is made up of only partly weathered rock?
parent material
