What is the oldest sedimentary rock?
In an undisturbed strata, the oldest layers are at the bottom. It's called the law or principle of superposition.
What states that in undisturbed rock layers the oldest rocks are on the bottom and the rocks become progressively younger toward the top?
principle of superposition
The concept that the oldest layer will be at the bottom in an undisturbed sequence of sedimentary strata is called the Principle of?
superpostion
How do a geologist use the principle of superposition?
A geologist uses the principle of superposition to determine the relative ages of rocks and sedimentary layers. This principle states that in undisturbed layers of rock, the youngest layers are at the top while the oldest layers are at the bottom. By observing the order in which different rock layers are stacked, a geologist can infer the sequence of events that happened over time in a particular location.
What does the principle of superposition state?
Layers at the bottom are the oldest.
What is the oldest sedimentary rock?
In an undisturbed strata, the oldest layers are at the bottom. It's called the law or principle of superposition.
Where are the oldest layers of sediments located?
The oldest layers of undisturbed sediment are at the bottom.
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 states that in undisturbed rock layers the oldest rocks are on the bottom and the rocks become progressively younger toward the top?
principle of superposition
How are the layers of rock if they are undisturbed?
The undisturbed rock layers are horizontal and in order of age from youngest nearest the surface to oldest at the bottom of the rock unit.
The concept that the oldest layer will be at the bottom in an undisturbed sequence of sedimentary strata is called the Principle of?
superpostion
What does the The Law of Superposition state?
Principle stating that older rock layers are beneath younger rock layers.
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.
What is law of superpostion?
In geology, the law of superposition states that in any undisturbed sequence of rocks that are deposited in layers, the oldest layers are on the bottom. Each layer is younger than the layer below it.
What can you tell from undisturbed rock layers?
You can tell the age of the layers. The bottom layer is the oldest and the top is the youngest. When the layers are disturbed they tend to get bent and messed up and you cannot tell the age
How do you determine the order of rock layers?
The chronological order of rock layers is usually determined by their order in an undisturbed sequence of strata. According to the principle of superposition, the oldest layers would be found at the bottom and the youngest layers at the top. In disturbed rock layers (those that have been folded, uplifted, or generally disrupted by tectonic forces), the determination must be made based on the presence of index fossils, comparison to undisturbed strata or radiometric dating.
