Is the youngest or oldest rock on top?
The youngest rock is typically found on top in a sequence of rock layers due to the principle of superposition, which states that younger rocks are deposited on top of older rocks. This means that the oldest rock is usually located at the bottom of a sequence of rock layers.
Where is the youngest layer of rock found?
On the top
What rock layer is the youngest?
The principle of superposition states that in an undisturbed sequence of rock layers, the youngest will be at the top, the oldest at the bottom.
What layer is the youngest layer in the sedimentary rock?
The one closest to the surface because rock layers are laid down one on top of another.
The rock at the bottom of an undisturbed sequence is?
The bottom is oldest. The top is newest. -From bottom to top is the equivalent of oldest to youngest in an undisturbed sequence.
Is the top layer of rock the youngest layer?
According to the Law of Superposition, in a depositional sequence of undisturbed rock layers, the top layer of rock is the most recent to form from the processes of lithification or eruption of lava onto the surface, and are therefore the youngest rock layers.
What does the law of superposition tell us about rock layers?
youngest on top
When might the youngest layer in a set of sedimentary rock not be on top?
1. If a set of rock layers has been disturbed by movement of tectonic plates, the youngest layer may no longer be on top.
Where is the youngest rock usually found?
in the middle of the ocean ridge
Is young rock age on the bottom or top of a chart or graph?
Youngest at the top, oldest at the bottom, just as in nature.
In which layer of rock shown below are the fossils the youngest?
The fossils are typically found in the uppermost layer of rock, as sedimentary rock is formed from the accumulation of materials over time. Newer layers are deposited on top of older layers, meaning that the youngest fossils would be located in the most recent (top) strata. Therefore, the youngest fossils are in the layer that is highest in the sequence shown.
Which is the youngest in a sereis of undisturbed rock layers where shale lies between sandstone below and limestone above?
The shale layer is the youngest in the series. In undisturbed rock layers, the Law of Superposition states that the youngest layer is on top and the oldest is at the bottom. So, in this case, the limestone would be the oldest layer, followed by sandstone, and then shale.
