Is a layer younger or older than the layers it cuts through?
A fault is necessarily younger than faults it cuts through; it could not have happened if the layers were not there first.
If a fault occurs in an area where rock layers have been folded what type fault would it be?
What is the relative age of a fault that cuts across three horizontal sedimentary rock layers?A. The fault is older than the middle layer. B.The fault is younger than all the layers it cuts across.C. The fault is the same age as the top layer. D. The fault is older than all the layers it cuts across == ==
Is the fault older or younger than rock layer A?
older because it is at the bottom and the ones on top are younger than the bottoms
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."
Intrusions of the igneous rock are younger or older than the rock layers beneath and surrounding them?
they are younger and extrusions are older. they are younger because the surrounding rock layers had to have been there first in order for it to appear. :)
Which is younger a fault or sandstone?
One is not necessarily older than the other. It depends on the context. A fault running through any rock must be younger than that rock.
Are rock layers always younger than the faults that cut across them?
If the situation is as simple as the one you have stated, it isn't difficult. Meanwhile, many faults displace laterally, either in compression or tension so that it can appear that younger rocks overlie older ones. See the law of super-position. Compressive faults generally force younger rocks below older, but not always. See subduction zones. Then see ophiolite suites.
Are the layers of rock above and below the coal older or younger?
Every layer of rock, as one moves up from the core, is younger than the one below it. This means that the layers of rock above and below the coal are different ages, with the one above younger and the one below older.
How do you know that an intrusion is younger than its surrounding rock layers?
younger over older is a phrase you can use to remember this principle.
How is the fault younger than three rock layers?
The rock layers that a fault passes through had to have already existed for them to break and create a fault. This is analogous to the door panel of your car had to have already existed for it to bend and create a dent.
Is an extrusion older or younger than the rock layer below it?
Extrusion is older than intrusion because, an extrusion is always younger than the rocks below it. An intrusion is always younger than the rock layers around and beneath it. Hope the answers correct ;)
How is it that crosscutting feature is always younger than the rock layers in cuts across?
A crosscutting feature is always younger than the rock layers it cuts through because the feature always forms after the rock layers have been formed, making the rock layers older.
