The law of superposition states that in any undisturbed sequence of sedimentary rocks, the oldest layers are at the bottom and the youngest are at the top. In a cross section of rock layers, this principle can be applied by examining the arrangement of the strata; the lowest visible layers would represent the earliest geological formations, while the uppermost layers would indicate more recent deposits. Any disruptions, such as faults or intrusions, must be considered to accurately interpret the chronological sequence of events. By analyzing the relationships between these layers, geologists can reconstruct the geological history of the area.
What else can I help you with?
According to the law of superposition the lowest layer in a cross section of rock is what?
According to the law of superposition, the lowest layer in a cross section of rock is the oldest, as sedimentary rocks are typically laid down in sequence with the oldest rocks at the bottom and the youngest at the top.
What are the guidelines used to determine the relative ages of the rocks and events shown by a geologic cross section?
The guidelines used to determine the relative ages of the rocks and events shown by a geologic cross-section is the Law of Superposition. It is the basic law of geochronology.
How does this cross section indicates that the Stockton sandstone is the oldest rock layer?
In a geological cross-section, the principle of superposition states that in undisturbed sedimentary layers, the oldest layers are at the bottom and the younger layers are deposited on top. If the Stockton sandstone is depicted at the lowest level of the cross-section, it indicates that it was formed first, before the overlying layers. Additionally, if there are no intrusions or significant folding that would disrupt this order, it further supports the conclusion that the Stockton sandstone is the oldest rock layer.
Stem's cross section?
Most plant stems are hollow - giving a cross-section that resembles a donut.
A water heater draws 40A from a 120V power source in 10m away What is the minimum cross section of the wire that can be used if the voltage applied to the heater is not lower than 115V?
To maintain a voltage drop of less than 5V over the 10m distance at a current of 40A, you would need a wire with a minimum cross section of 6 AWG. This size of wire will help ensure that the voltage applied to the heater remains not lower than 115V, taking into account voltage drop considerations due to the length and current draw.
According to the law of superposition the lowest layer in a cross section of rock is what?
According to the law of superposition, the lowest layer in a cross section of rock is the oldest, as sedimentary rocks are typically laid down in sequence with the oldest rocks at the bottom and the youngest at the top.
According to the principle of superposition the lowest layer in a cross section of a rock sequence?
According to the principle of superposition, the lowest layer in a cross section of a rock sequence is the oldest, as younger layers are deposited on top of older layers. This principle helps geologists determine the relative ages of rock layers by analyzing the order in which they were formed.
What are the guidelines used to determine the relative age of a rocks and events shown by a geologic cross-section?
The guidelines used to determine the relative ages of the rocks and events shown by a geologic cross-section is the Law of Superposition. It is the basic law of geochronology.
4 How does the type and direction of stress applied affect the selection of the material and the cross section?
12
What is a direct axial load?
It is a load applied in the axis of the member perpendicular (normal) to the cross section.
What could not be the shape of a cross section of a cylinder?
A square.
What would the cross section of a square pyramid be?
Depending on the inclination of the plane used for the cross-section, it could be a square, rectangle, trapezium, triangle.
What are the guidelines used to determine the relative ages of the rocks and events shown by a geologic cross section?
The guidelines used to determine the relative ages of the rocks and events shown by a geologic cross-section is the Law of Superposition. It is the basic law of geochronology.
What could not be the shape of a cross section of this cylinder?
A square.
How do you put cross-section into a sentence?
The architect presented a detailed cross-section of the building, illustrating the various layers of materials used in its construction. By examining the cross-section, the engineers could better understand how to optimize the structural integrity of the design.
Will an increase of applied voltage decrease the resistance of a copper conductor?
No, the resistance is fixed by the cross section and length of the conductor and does not vary with voltage.
How does this cross section indicates that the Stockton sandstone is the oldest rock layer?
In a geological cross-section, the principle of superposition states that in undisturbed sedimentary layers, the oldest layers are at the bottom and the younger layers are deposited on top. If the Stockton sandstone is depicted at the lowest level of the cross-section, it indicates that it was formed first, before the overlying layers.
