Extrusion is older than intrusion because, an extrusion is always younger than the rocks below it. An intrusion is always younger than the rock layers around and beneath it. Hope the answers correct ;)

Is the extrusion older or younger than top and bottom rock?

To determine if the extrusion is older or younger than the top and bottom rock layers, you can apply the principle of superposition, which states that in an undisturbed sequence of sedimentary rocks, the oldest layers are at the bottom and the youngest are at the top. If the extrusion cuts through the rock layers, it is younger than the rocks it intrudes. Conversely, if the rock layers wrap around the extrusion, then the extrusion is older. Without specific details about the geological context, this is the general approach to answering the question.


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.


In general the law of superposition states that in an undeformed sequence of sedimentary rock each layer is?

Younger than the layer below it.


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.


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.


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.


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


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.


What is the law of the geological principle that states that in horizontal layers os sedimentary rock each layer is ilder than the layer above or below it and younger than the layer below it?

The law you are referring to is known as the Law of Superposition. This principle states that in any undisturbed sequence of sedimentary rocks, the oldest layers are at the bottom, with younger layers deposited on top. As a result, each layer of rock is older than the layer above it and younger than the layer below it, providing a chronological framework for understanding geological history.


Is the fault older or younger the rock layer A Explain?

To determine whether the fault is older or younger than rock layer A, we can use the principle of cross-cutting relationships. If the fault cuts through rock layer A, it is younger than that layer, as it must have formed after the rock was deposited. Conversely, if rock layer A is found to be disrupted by the fault, then the fault is older. Therefore, examining the relationship between the fault and rock layer A is key to establishing their relative ages.


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.


Brief note on the law of superposition?

It is a law that the higher the rock layer is the younger it is. The deeper it is the older the rock layer is.
