Define: Index fossils
fossil considered to represent a certain period In Earth's past
Define: Geological column
a theoretical picture in which layers of rock from around the world are mashed together into a single, on a broken record of Earth's past
Define: The Theory of Evolution
a theory which states that all of life on this earth has a single, common ancestor that existed a long time ago
How are index fossils used by geologists?
index fossil are used by geologists to determine what time period of layer of rock rock rap resent. If a geologist find index fossil for the cabrain time period In a layer of rock, for example, the geologist says that the layer of rock was laid down during can bring times.
Is it possible to go somewhere in the world and see all major layers of the geological column in one geological formation?
no. The geological column is not something that exist somewhere in the world. It is a construct base on uniformitarian assumption.
According to the uniformitarian view, which creatures lived on earth first: trilobites or fish?
sense trilobites are lower on the geological column uniformitarians assume that trilobites existed on Earth to before fish
If a paleontologist finds only fossil algae in a layer of rock, roughly how old does the geologist think the rocks are?
when only algae are found in a layer of rock, geological column says that the rock is assumed to be Precambrain,which is assumed to be five hundred seventy years old or older
A geological formation with only two layers of rock is studied. One has fossils of mammals only and the other has fossils of fish only. According to uniformitarian assumptions, which layer should be on the bottom and which should be on the top?
according to the geological column, fish came before mammals. This means the layer with only fish must be the older layer. Thus, the layer with fish should it be on the top bottom and the day you're with mammals should be on top.
Why is the geological column considered to be evidence for evolution?
The geological column is viewed as evidence for evolution because it indicates that early in early history, there were only simple life forms. As time went on, the geological column indicates that more and more complex life forms started to appear. This is exactly what the theory of evolution says.
Why is the geological column not really evidence for evolution?
the geological column is not really evidence for evolution because it is not real. since it is constructed with assumptions, the evidence is only good if the assumptions are valid.
what does the data from Mount St Helens tell us about the time it takes to form stratified rocks?
the data from Mount St Helens indicates that stratified rock can form in less than a day.
if you see a canyon with a river flowing at the bottom of it,should you assume that the river eroded the canyon?
no, you should not make that assumption. The only time we have actually observed a canyon form, it formed as the result of a catastrophe and then later the river forms. Thus, the data from Mount St Helens tell us that canyons cause rivers, not that rivers cause canyons.
on a geological scale, was the Mount St Helens eruption a major catastrophe? What does that tell you about the kind of geological formations which can be formed in a major catastrophe?
on a geological time scale, the Mount St Helens cut astrophe was rather miner. This tells us that a major catastrophe would most likely result in larger deposits of stratified rocks and larger canyons.
what did the Mount St Helens eruption have that the major flood would also have?
the Mount St Helens eruption had mudflows. These mudflows caused most of the geological features that have been studied, and a major flood what also have such mudflows.
what is so important about the Cumberland bone cave when it comes to the question of uniformitarianism verses catastrophism?
the Cumberland bone cave is a fossil graveyard that contains many fossil from several different climates. This is important because it is excellent evidence for a worldwide flood and is a major problem for the uniformitarian for you point because it is not something that can be well explained in terms of uniformitarian assumptions.
Do fossil require millions of years to form?
no. fossilized hats, pliers, and water wheels tell us that fossil can form rapidly.
what is a paraconformity?
a paraconformity is an unconformity that does not really exist in a geologicauniformitarians believe must exist because of the fossils found in the formation.
list at least four problems with uniformitarianism as discussed in the text.
the text discusses the following problems-you need only list four of them:a. There are too many fossiles in the fossil record. b. fossil graveyards with fossiles from many different climates are hard to understand in the uniformitarian view. C. Index fossil are called into question by the many creatures we once thought were extinct but now know are not. D. uniformitarian must assume the existence of paraconformities.
what are the three problems with catastrophism that were discussed?
catastrophists have offered no good explanation for the existence of unconformities between rock layers laid down by the blood. They also cannot explain certain fossil structures that look like they were formed under normal conditions which would not exist during the flood. Finally, they have not yet explained the enormous amount of limestone that exists all over the world in terms of Noah's flood.
why does the fossil record offer no evidence for evolution?
the fossil record contains no fossils that are undeniable intermediate links. If evolution occurred, there should be millions of such fossils.
why does the fossil record of for evidence for the idea that God created each plant and animal individually?
the fossil record contains no fossil that are undeniable intermediate links. This is exactly what you would expect if God created each plant and animal individually.
