What evidence did cross-cutting relationships give geologists?
Cross-cutting can give insight to whether or not a certain layer is older or younger than what is cross-cutting it. Say if a dike was cross-cutting layer A, then layer A is older than the dike.
Is the fault older or younger the rock layer A Explain?
To determine whether the fault is older or younger than rock layer A, we can use the principle of cross-cutting relationships. If the fault cuts through rock layer A, it is younger than that layer, as it must have formed after the rock was deposited. Conversely, if rock layer A is found to be disrupted by the fault, then the fault is older. Therefore, examining the relationship between the fault and rock layer A is key to establishing their relative ages.
Which layer is older than oceanic crust made of granites and relatively thick?
Continental Crust.
How can you tell that sandstone is older than a basalt layer?
If the sandstone is below the basalt layer, it is older. Though caution is advised, to make sure it is really a basalt layer and not an intrusion of gabbro. Other indicators that the sandstone is older is evidence of alteration to the sandstone where the two meet (called a "baked contact") and pieces of sandstone being found in the the basalt.
A fossil found under a layer of rock is usually?
older than the rock layer above it and can provide information about the time period in which it lived and the environmental conditions at that time. This helps scientists estimate the age of the rock layers and understand the history of the area where the fossil was found.
Which period is older than the Triassic period?
The Jurassic Period followed the Triassic.
What evidence did cross-cutting relationships give geologists?
Cross-cutting can give insight to whether or not a certain layer is older or younger than what is cross-cutting it. Say if a dike was cross-cutting layer A, then layer A is older than the dike.
What is a fossil found under a layer of rock is usually?
It is usually older than the rock layer it is found under.
What is A fossil found under a layer of rock is usually .?
It is usually older than the rock layer it is found under.
What is the defointion for the law of superstition?
the law of superstition is the geologi principle that states that in horizontal layers of sedimentary rock.Each layer is older than the layer above it and younger than the layer below it

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 statements states relative age?
"The fossils found in this rock layer are older than the fossils found in the layer above it." "The granite intrusion is younger than the surrounding sedimentary rocks." "The volcanic ash layer is slightly older than the layer of soil above it." "The erosion pattern on the hillside indicates that the granite rocks are older than the layers of sediment deposited on top of them." "The cross-cutting relationship between the fault and the layers of rock indicate that the fault is younger than the rock layers it cuts through."
Evaluate the age of rocks You find three undisturbed rock layers The middle layer is 120 million years old What can you say about the ages of the layers above and below it?
The layer above the 120 million-year-old layer must be younger, and the layer below must be older. So, the layer above the middle layer will be younger than 120 million years, and the layer below the middle layer will be older than 120 million years.
Which layer is older than oceanic crust made of granites and relatively thick?
Continental Crust.
What are some Triassic period fossils?
Icthyosaurs and plesiosaurs are both known from Triassic strata. Crinoids were common then, but their history spans more than just the Triassic. Coelophysis appeared in the middle of the Triassic. Phytosaurs and aetosaurs did not survive past the end of the Triassic. Lystrosaurus was a Triassic dicynodont, about the size of a sheep, which has been found on every continent (including Antarctica). Podocarps and other gymnosperms (plants) survived beyond the Triassic period.
Which layers are older then layer c?
Layers A and B are older than layer C, based on the principle of superposition which states that in undisturbed sequences of rock, the oldest rock layers will be at the bottom and the youngest at the top.
