Use the dropdown menu to make the following statement true.(1 point)
The Law of
states that a fault or intrusion of rock is younger than the formation that it cuts through.
The Law of
states that a fault or intrusion of rock is younger than the formation that it cuts through.
The correct completion for the statement is "Cross-Cutting Relationships."
So, the full statement reads:
"The Law of Cross-Cutting Relationships states that a fault or intrusion of rock is younger than the formation that it cuts through."
Fault B cuts across several layers of rock. Which conclusion can be made?
(1 point)
Responses
Fault B is older than layer C based on the law on inclusion
Fault B is older than layer C based on the law on inclusion
Fault B is younger than layer C based on the law of crosscutting
Fault B is younger than layer C based on the law of crosscutting
Fault B is younger than layer D base on the law of inclusion
Fault B is younger than layer D base on the law of inclusion
Fault B is older than layer D based on the law of crosscutting

Responses
Fault B is older than layer C based on the law on inclusion
Fault B is older than layer C based on the law on inclusion
Fault B is younger than layer C based on the law of crosscutting
Fault B is younger than layer C based on the law of crosscutting
Fault B is younger than layer D base on the law of inclusion
Fault B is younger than layer D base on the law of inclusion
Fault B is older than layer D based on the law of crosscutting
The correct conclusion is:
Fault B is younger than layer C based on the law of crosscutting.
This is because the law of crosscutting states that a geological feature (like a fault) that cuts through other layers must be younger than the layers it disrupts. Thus, since Fault B cuts across the layers, it must be younger than those layers.

According to the Law of Superposition, the oldest organism among the options provided would be the Trilobite.
Trilobites existed during the Paleozoic Era, well before dinosaurs, shells, or birds, which appeared later in Earth's history.

In horizontal layers of sedimentary rock, Rock layer A is older than Rock layer B.
In horizontal layers of sedimentary rock, Rock layer A is older than Rock layer B.
I am older than my sister.
I am older than my sister.
The half-life of carbon-14 is 5,730 years
The half-life of carbon-14 is 5,730 years

I am older than my sister.
The half-life of carbon-14 is 5,730 years
The half-life of carbon-14 is 5,730 years
The extrusion is younger than the rock layer below it.
The statement that best gives an example of absolute age is:
The half-life of carbon-14 is 5,730 years.
This statement provides a specific measure of time, which is indicative of absolute dating, whereas the other options are more relative comparisons.

Fern because it appears in multiple layers (long period of time) and in 3 columns (multiple areas)
Trilobite because it only appears in one layer (limited time) and in one column (single area).
Trilobite because it only appears in one layer (limited time) and in one column (single area).
Ammonite because it appears in only 1 layer (limited time) but in 3 columns (multiple areas).

Ammonite because it appears in only 1 layer (limited time) but in 3 columns (multiple areas).
A good example of an index fossil should be a species that is widespread but existed for a relatively short period of geological time, allowing geologists to date the rock layers.
Based on the options provided, the correct choice would be:
Gastropod because it appears in multiple layers (long period of time) and in 3 columns (multiple areas).
This indicates that the gastropod is widely distributed across various locations and stratigraphic layers, which is characteristic of good index fossils.
