Why would newer rock layers ever be below older rock layers?
Due to faulting or folding.
Fossils in newers layers of earth tend to resemble current?
Organisms.Fossils found in newer layers of Earth's crust tend to be similar to present-day organisms.
What is rock layers?
rock layering is where you have one layer of old rock them a newer layer then an other newer layer.
How does the position of fossils in layers show evolutionary changes?
Assuming the layers aren't deformed, the lowest deposition layers are the earliest. Later deposition layers accumulate on top of the earlier layers. Thus, the lowest layers have the earliest fossils, and the highest layers have newer fossils. By comparing the features of early and late fossils of a species, you can determine some of its evolutionary changes. Of course, not all features survive in a fossil - soft tissues, for example.
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 The Law of Superposition state?
Principle stating that older rock layers are beneath younger rock layers.
What is the Law of Superposition?
Superposition is the principle that states that, in undisturbed strata, newer layers will be deposited over older layers; thus, in a core sample, those samples of earth and rock nearest the surface will be newer in age than those beneath them.

A place where an old eroded rock surface is in contact with a newer rock?
Is called an unconformity.
In layers of undisturbed sedimentary rock the oldest rocks are on the?
Factors such as wind, ice, and warder contribute to sedimentary build up. As this occurs older layers of sedimentary rock are driven lower while newer layers replace them closer to the surface.
What is the law of superpostition?
All this means is that if you see a diagram of rock layers, the oldest layers are on the bottom and the newer layers are on top.
Why would newer rock layers ever be below older rock layers?
Due to faulting or folding.
Fossils in newer layers of the earth tend to resemble current?
organisms

When archaeologists study an excavation site objects found closer to the surface are?
Not as old as those found deeper
How did the study of organisms on islands help support Darwin's ideas?
It Gave evidence and the fossil organisms on the bottom or older layers were more primitive than those in upper or newer layers.
