How the law of superposition helps scientist determine relative age?
Younger layers are deposited on top of older layers, whether the layer is sedimentary or volcanic. Occasionally faults may result in overthrusts, where a series of older layers may be pushed over the top of younger layers. But this is rare. In general, the older layers will be the lower layers.
Are older fossils found in higher layers of earth or lower layers?
lower0000
Which layers are older then layer c?
z
Younger layers of undisturbed sedimentary rock are above older layers according to?
the principal of sedimentarianism
When studying a stack of rock layers the layers are usually toward the bottom and the layers are usually toward the top?
Older ; Younger . 1 (; N.R.C.J
What does the law of superpositioning state?
Principle stating that older rock layers are beneath younger rock layers.
Why would newer rock layers ever be below older rock layers?
Due to faulting or folding.
What does the law superposition state?
Principle stating that older rock layers are beneath younger rock layers.
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.
What do an intrusion and an extrusion tell us about the rock layers?
(Intrusion) You can learn how old the rock layers are around it. the rock layers around under and all around the intrusion are always older than the intrusion itself. (EXTRUSION) the layers of rock bellow the extrusion is older than the extrusion.
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. :)
What is based on the idea that younger rock layers are deposited on top of older rock layers in undisturbed areas?
The answer is: Relative dating
