How does fossils size relate to faunal succession?
faunal succession is basically stating that the more complex something is, the younger it is. So the bigger the fossil is the younger it is.
Is it true to say that radioactive istopes in clastic sedimentary rocks always predict an age that is younger than the sedimentary rock?
That would not be true due to the fact that sedimentary clastic rock is composed of particles of pre-existing rock.
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
Is aragonite more likely to be found in younger or older fossils?
Aragonite only occurs in fossils of the Cainozoic era as the unstable polymorph aragonite rearranges its chemical structure to form more stable Calcite over time.
Would you expect to find fossils of an organism that lived relatively recently in old layers of rock or in younger layers?
No, not unless there was a large disturbance that rearranged the layers.
Where can you find the oldest fossils in sedimentary rock layers?
It would be found in the lower layers, rather that younger fossils which are found in the upper layers. ♥
Where are older fossils mostly found under or above younger fossils?
If the rocks containing the fossils have been involved in a mountain building episode they would be folded and if some of the folds were laid in a recumbent position and later eroded you would have older above younger rocks. Of course, it would be easy to find out if this was the case because of the various sedimentary structures in each separate layer of rock.
Any method of determining whether an event or object is older or younger than other events or objects?
fossil
What are the difference between reworked fossils and leaked fossils?
From the law of faunal succession,older beds are characterized by fossils of older age and the younger beds are characterized by younger age fossils.But in some exceptional condition the younger fossils are reported in the older formation and those are termed as leaked fossils. whereas,Fossils of older age occur in younger rock are known as reworked fossils.They are derived from the older rocks by reworking ad recycling of sediments.
Younger fossils and not older fossils are more like?
this is an incoherent question that cannot possibly be answered
How the law of superposition helps paleontologist?
Superposition is the methodology of younger sediments being deposited over older rocks. Paleontologists can determine the evolution or extinction of a species by looking at what fossils are either present or absent in a particular sedimentary layer.

What. Type of unconformity consists of tilted sedimentary rocks that are overlain by younger more flat lying sedimentary rocks?
angular unconformity
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."
What are the relative ages of igneous intrusion and overlying sedimentary rock layers that dome upward?
The intrusion is younger than the overlying sedimentary rock.
What does the principle of superposition tell you about the relative ages of sedimentary rock layers?
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.
Where would you typically find younger rocks?
If you are talking about sedimentary rock, and the idea of relative dating, then the younger rock would be on top closer the the surface.
