Does the law of superposition helps geologist determine the absoloute age of a rock layer?
no, the relative age
When you know the relative age of a fossil what else do you know about it?
the relative age of the rock where it was found.
What is a geological unit?
A geological unit is an identifiable - "mappable" volume or layer of rock where the relative age can be determined. The link below gives more detail.
How can the relative age of a rock be determined?
Layers that are farther beneath the surface are usually older in relativity to the layers that are closer to the surface.Geologists look for index fossils, evidences of specific organisms that were widespread, rapidly evolving, plentiful, and only existed during a specific geologic time period. Trilobites are an example of one such index fossil. When an index fossil is identified in a rock layer, it can be assumed that the age of the rock falls within the time period of the organism's existence. This is called relative dating, and is used in field study as a quick reference to the age of a rock stratum.
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
What does relative dating provide for the age of a rock layer or fossil?
estimate

Does the law of superposition helps geologist determine the absoloute age of a rock layer?
no, the relative age
What genaral statement can be made about the age of any rock layer?
the bottom is the oldest and the top is the youngest
What is the best indication of relative age of a rock layer?
blah blah blah blah
What is the best indication of a relative age of a rock layer?
The position of the layer compared to other layers.
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.
What suggests relative age?
The position of a layer of rock or sediments in relation to the other layers in undisturbed strata suggests its relative age, according to the principle of superposition and the law of horizontality.
How can fossills be used to determine the relative ages of rock layers?
fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.
Which phrase describes the relative age of a rock?
refers to how old a certain rock or rock layer is compared to another rock
What is the definition of relative age?
The geologic age of fossil organisms, rock, or geologic features or events defined relative of each other.
What is the relative age of a fossil starfish?
the relative age of the rock where it was found.
