What else can I help you with?
Are black diamonds more or less expensive than regular diamonds?
Black diamonds are more porous and from younger sedimentary rocks, so they are not as expensive as other diamonds.
What is a synonym for minor?
secondary, insignificant, trivial, unimportant
What is the focus of early communication for infants younger than 12 months?
emotion
Is Perdita Weeks and Honeysuckle Weeks related?
Yes. Perdita is Honeysuckle's younger sister.
Any method of determining whether an event or object is older or younger than other events or objects?
fossil
What states That I an undeformed sequence of sedimentary rocks each bed is older than the one above it?
The principle you're referring to is known as the Law of Superposition, which states that in an undeformed sequence of sedimentary rocks, each layer (or bed) is younger than the one beneath it and older than the one above it. Therefore, if a sequence is undeformed, the oldest layers will be at the bottom and the youngest at the top. This principle is fundamental in geology for understanding the relative ages of rock layers and the history of the Earth.
In general the law of superposition states that in an undeformed sequence of sedimentary rock each layer is?
Younger than the layer below it.
What fundamental concept states that in a horizontal sequence of conformable sedimentary strata each higher bed is younger than the bed below it?
The fundamental concept you are referring to is the Law of Superposition. It states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are found at the bottom, while the youngest rocks are found at the top.
What is the geologic columnused in relative dating?
1.Geologists use the geologic column to help them interperet rocks sequences. 2.they use to help them identify rock layers in complicated rock sequence.
Where is the oldest rock layer in an undisturbed rock sequence?
In an undisturbed rock sequence, the oldest rock layer is typically found at the bottom. This is due to the principle of superposition, which states that in sedimentary rock layers, younger layers are deposited on top of older ones. Thus, as you move upwards through the sequence, the age of the rock layers decreases.
What are the 3 laws of relative dating?
Law of Superposition: In an undisturbed sequence of rock layers, the oldest rocks are at the bottom and the youngest are at the top. Law of Original Horizontality: Sedimentary rocks are deposited in horizontal layers. Law of Cross-Cutting Relationships: Any rock layer or geologic feature that cuts across another rock layer is younger than the rock layer it cuts across.
What geologic law is applied if an igneous intrusion is observed through a layer of sedimentary rock?
The principle of cross-cutting relationships is applied in this case. It states that the intrusion must be younger than the sedimentary rock it cuts through, as the igneous rock is "cutting across" pre-existing layers. This helps in determining the relative ages of the rocks involved.
What characteristic most directly distinguishes an angular unconformity from a nonconformity?
An angular unconformity is characterized by tilted or folded sedimentary layers overlain by horizontal layers, indicating a period of deformation and erosion before new deposition. In contrast, a nonconformity is marked by the erosion of older igneous or metamorphic rocks, with younger sedimentary layers deposited on top, showing a gap in the geologic record due to uplift and erosion.
What is the definition angular unconformity?
Angular unconformity is a type of unconformity in which tilted or folded rock layers are overlain by horizontal rock layers. This indicates a period of deformation and erosion followed by deposition of younger sedimentary layers. It represents a gap in the geologic record.
What. Type of unconformity consists of tilted sedimentary rocks that are overlain by younger more flat lying sedimentary rocks?
angular unconformity
Younger layers of undisturbed sedimentary rock are above older layers according to?
the principle of superposition, which states that in an undisturbed sequence of rock layers, the youngest layer is on top and the oldest is on the bottom. This principle helps geologists determine the relative ages of rock layers based on their position in a stratigraphic sequence.
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.
