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?

Would you expect to find fossils of an organism that lived relatively recently in old layers of rock or in younger layers?
Fossils of an organism that lived relatively recently would be expected to be found in younger layers of rock, as they would not have had sufficient time to become buried and fossilized in older layers. Fossils of older organisms tend to be found in deeper, older layers of rock.
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.
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 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 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.
Is the fault older or younger than the layers?
older because it is at the bottom and the ones on top are younger than the bottoms
What is likely to be true about the age of rocks in deeper and deeper layers?
In general, rocks found in deeper layers are older than rocks found in shallower layers due to the principle of superposition, which states that younger rocks are usually on top of older rocks. This is based on the idea that sedimentary rock layers are deposited in chronological order over time.
Why is it that the lower an object is in the ground the older it is?
As sedimentary layers form over time, the lower layers end up being older than the layers deposited on top, due to the principle of superposition. This concept helps geologists determine the relative ages of different geological features based on their positions within the rock layers.
One of the key principles of relative dating is the law of superposition which states that?
Younger layers of sedimentary rock are deposited on older layers
