A fault is necessarily younger than faults it cuts through; it could not have happened if the layers were not there first.
What else can I help you with?
How the law of superposition helps scientist determine relative age?
Younger layers are deposited on top of older layers, whether the layer is sedimentary or volcanic. Occasionally faults may result in overthrusts, where a series of older layers may be pushed over the top of younger layers. But this is rare. In general, the older layers will be the lower layers.
How is it that crosscuting feature is always younger than the rock layer it cuts across?
A crosscutting feature is always younger than the rock layers it cuts through because the feature always forms after the rock layers have been formed, making the rock layers older.
Could you tell me something about realative ages of rocks for a project please?
When you look at a rock that has undisturbed layers, the bottom layers are older and the upper layers are younger. Anytime a rock layer crosses another (ie. an intrusion), the crossing layer is younger.
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."
If middle layer of rock is 120 million years old what can be said about above and below layer?
The layers above the 120 million-year-old middle layer are likely younger, while the layers below are likely older. This indicates a relative chronological sequence in the deposition of the rock layers, following the principle of superposition in geology.
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.
Is the fault older or younger than rock layer A?
The fault is younger than rock layer A. This is because faults are fractures in the Earth's crust that form after the deposition of rock layers, and activities like faulting can occur long after the rock layers have been deposited and solidified.
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.
Do you find older rock above or below younger rock?
The law of superposition states: in horizontal rock layers, each layer is older than the one above it and younger than the one below it.
Evaluate the age of rocks You find three undisturbed rock layers The middle layer is 120 million years old What can you say about the ages of the layers above and below it?
The layer above the 120 million-year-old layer must be younger, and the layer below must be older. So, the layer above the middle layer will be younger than 120 million years, and the layer below the middle layer will be older than 120 million years.
What is the defointion for the law of superstition?
the law of superstition is the geologi principle that states that in horizontal layers of sedimentary rock.Each layer is older than the layer above it and younger than the layer below it
Where is the oldest rock layer in an undisturbed rock sequence?
In an undisturbed rock sequence, the oldest rock layer is typically found at the bottom. This is due to the principle of superposition, which states that in sedimentary rock layers, younger layers are deposited on top of older ones. Thus, as you move upwards through the sequence, the age of the rock layers decreases.
