What else can I help you with?
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.
Would you expect to find fossils of an organism that lived relatively recently in old layers of rock or in younger layers?
Fossils of an organism that lived relatively recently would be expected to be found in younger layers of rock, as they would not have had sufficient time to become buried and fossilized in older layers. Fossils of older organisms tend to be found in deeper, older layers of rock.
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 is it called when a top of the rock is younger than the bottom layer?
It is called "overturned stratigraphy" or "inverted stratigraphy." This occurs when the rocks have been folded or overturned due to tectonic forces, resulting in the older layers appearing on top and the younger layers underneath.
Why are the oldest fossils sometimes not on the bottom layers of rocks?
Older fossils may not always be found at the bottom layers of rocks due to geological processes like folding, faulting, or erosion, which can disrupt the original order. In these cases, older fossils may be found at higher layers while younger fossils are found in lower layers.
Intrusions of the igneous rock are younger or older than the rock layers beneath and surrounding them?
Intrusions of igneous rock are typically younger than the rock layers they penetrate. This is because the magma that forms igneous intrusions is usually injected after the surrounding rocks have already solidified and formed.
Is the fault older or younger than the layers?
older because it is at the bottom and the ones on top are younger than the bottoms
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.
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 does the law of superpositioning state?
Principle stating that older rock layers are beneath younger rock layers.
Is a layer younger or older than the layers it cuts through?
A fault is necessarily younger than faults it cuts through; it could not have happened if the layers were not there first.
Would you expect to find fossils of an organism that lived relatively recently in old layers of rock or in younger layers?
Fossils of an organism that lived relatively recently would be expected to be found in younger layers of rock, as they would not have had sufficient time to become buried and fossilized in older layers. Fossils of older organisms tend to be found in deeper, older layers of rock.
What is superpostioning?
The Law of Superposition states that younger layers of deposition will form on top of older layers of deposition.
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.
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
How is it that crosscutting feature is always younger than the rock layers in 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.
Which scientific principle states that younger rock layers are generally deposited on top of older rock layers and why?
Superposition
