Correlating rock layers is comparing two rock layers to each other. I hope that this helps :)
Actually its the matching up of rocks of the same age from place to place is called correlation of the rock layers. I hope that this helps :)

∙ 13y agoCertain plants and animals, or certain groups of plants and animals are known to have lived at specific times. This information comes from areas where there are easily datable materials in the layers around the fossils of these plants and animals.
If that group of fossils is seen elsewhere, you can infer that those rocks have the same age as the rocks that were previously dated.

∙ 13y agoin a nutshell...dating of layers of rock is based on stratification...layers of rock that are at a deeper place in the earth are older and they get more recent as they go to the top...the ages of the different layers (or strata) are relative the others around it...

Why do geologists correlate rock layers?
Within a small area, you can correlate the rocks of one locality with those of another by simply walking along the outcropping edges. However, this might not be possible when the rocks are covered by soil and vegetation. This problem can be corrected if you note the position of a distinctive rock layer in a sequence of strata. You may be able to identify a rock layer in another location if it's composed of very distinctive or uncommon minerals.
What can she infer about the ages of the two rock layers?
That the one below the other is generally older.
Which rock has many layers?
Sedimentary rock.Or more in geology and related fields, a stratum (plural: strata) is a layer of rock or soil with internally consistent characteristics that make it different it from contiguous layers either side of it. Each layer is generally one of a number of parallel layers that lie one upon another, laid down by natural forces.A sedimentary rock is one form of rock that can be stratified, but there are other examples of strata that are not sedimentary on origin (e.g. a layered igneous body or a flood basalt).
Why is the top layer the youngest in a sedimentary rock?
that's easy, dirt is on the ground and over the yyears more dirt and rock cover it, subsequently every new layer of ground goes on top of the last one making the most current one the one top with other layers increasing in age as you go further down.
How does a geologist know that layers are undisturbed?
When a rock is disturbed, it usually contains one of the following abnormalities:SlantingBendingFoldingCrackingMetamorphismor Nonconformities.If a rock layer contains none of these, then geologists classify it as undisturbed.

How many layers do metamorphic layers have?
a metamorphic rock is a rock that has been changed from one rock to another by heat and/or pressure.....they amount of layers would depend on what kind of rock.....all rocks have a different amount of layers sorry
Are the layers of rock above and below the coal older or younger?
Every layer of rock, as one moves up from the core, is younger than the one below it. This means that the layers of rock above and below the coal are different ages, with the one above younger and the one below older.
If the same types of fossils are found in two separate rock layers it's likely that the two rock layers form?
If the same types of fossils are found in two separate rock layers, it is likely that the two rock layers are part of one continuous deposit.
If the same types of fossils are found in two separate rock layers it's likely that the two rock layers form what?
If the same types of fossils are found in two separate rock layers, it is likely that the two rock layers are part of one continuous deposit.
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.
What is one thing that tells a geologist that rock layers have been disurbed?
If rock layers are not horizontal, then some force must have diturbed them after they were fomed.
If the same types of fossils are found in two separate rock layers, it's likely that the two rock layers?
a part of one continuious deposit.
What rock has layers?
There are many types of rock but this one would either be Sedimantary Igneous Metamorphic
How do you determine which rock layers are older than other when looking many layers of rock piled on top of one another?
bope bop bope bpo
Are layers of rock above and below the coal or older and younger?
Every layer of rock, as one moves up from the core, is younger than the one below it. This means that the layers of rock above and below the coal are different ages, with the one above younger and the one below older.
What does correlate?
Correlate means to connection one thing to another in terms of how they relate to one another. For example one could write a paper to correlate how dropping out of school leads to working jobs that do not pay well.
