Are the layers of rock above and below the coal older or younger?
The layers of rock above the coal are younger, while the layers of rock below the coal are older. This is because sedimentary layers are deposited in a chronological sequence with the oldest rocks at the bottom and the youngest rocks at the top.
Is the layer of rock at the bottom of a sedimentatry rock younger or older?
The layer of rock at the bottom of a sedimentary rock is older. This is due to the principle of superposition, which states that in an undisturbed sequence of rock layers, the oldest rocks are at the bottom and the youngest are at the top.
How can older rocks be found above younger rocks in a cross section?
There are two possible explanation. In one cases the underlying younger rock could be an igneous intrusion, formed when molten rock was injected into pre-existing rock and then cooled. Another explanation might be that the beds were overturned as the rock was deformed and tilted.
One of the key principles of relative dating is the law of superposition which states that?
Younger layers of sedimentary rock are deposited on older layers
What law suggests that older rock strata are at the bottom and younger rock strata are at the top?
The law that suggests that older rock strata are at the bottom and younger rock strata are at the top is the law of superposition. This principle states that in an undisturbed sequence of sedimentary rocks, the oldest rocks will be at the bottom and the youngest at the top due to the natural layering process over time.
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.
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.
Are the layers of rock above and below the coal older or younger?
The layers of rock above the coal are younger, while the layers of rock below the coal are older. This is because sedimentary layers are deposited in a chronological sequence with the oldest rocks at the bottom and the youngest rocks at the top.
What does the idea of superposition say about rock layers have not been disturbed?
It states that younger rocks lie above older rocks if the layers have not been disturbed.
What does the idea of superposition say about the rock layers that have not been disturbed?
It states that younger rocks lie above older rocks if the layers have not been disturbed.
What the idea of superposition say about Rock layer that have not been disturbed?
It states that younger rocks lie above older rocks if the layers have not been disturbed.
In general the law of superposition states that in an undeformed sequence of sedimentary rock each layer is?
Younger than the layer below it.
Is the layer of rock at the bottom of a sedimentatry rock younger or older?
The layer of rock at the bottom of a sedimentary rock is older. This is due to the principle of superposition, which states that in an undisturbed sequence of rock layers, the oldest rocks are at the bottom and the youngest are at the top.
How could you tell an older rock from a younger rock just by looking at their isochrons?
You could tell an older rock from a younger rock by looking at it because the older rock isochron would have a steeper slope.
What term denotes blocks of older rock enclosed in a body of younger igneous rock?
Xenoliths are blocks of older rock enclosed in a body of younger igneous rock.
How can older rocks be found above younger rocks in a cross section?
There are two possible explanation. In one cases the underlying younger rock could be an igneous intrusion, formed when molten rock was injected into pre-existing rock and then cooled. Another explanation might be that the beds were overturned as the rock was deformed and tilted.
Which scientific principle states that younger rock layers are generally deposited on top of older rock layers and why?
Superposition
