Holt McDougal Earth Science Chapter 6 – The Rock and Fossil Record Chapter Exam

Much of northern New Jersey was covered with glaciers during the last ice age. While digging in this region, a geologists discovers bands of light- and dark-colored clays just below the surface. What are these sediments and how is the geologist most likely to determine their age? Identify the type of unconformity shown in the diagram below and describe how it formed. Identify the two types of unconformities in the diagram below and describe how they formed. Contrast relative-age dating and absolute-age dating.

Its fairly precise up unto about 5, years, but after that there is really no way to calibrate it, that means to verify it by some other independent method, so it works out ok to a point. Also, there’s no reason that things have always been exactly the same as far as decay rates are concerned. Mayor changes could have occurred when God cursed the ground or during the flood.

I believe that all of the fossil fuels and things like that resulted from the flood. This is why they contradict each other.

Fast facts on the fossil record All the different kinds of animals appear abruptly and fully functional in the strata with no proof of macroevolutionary ancestors. At the very least, this is a strong indication that not all life evolved from a common ancestor. There is no scientific proof that life has evolved. Although scientists will continue to discover new varieties of fossil animals and plants, it is generally agreed that the millions of fossils already discovered and the sediments already explored provide a generally reliable indication of which way the evidence is going.

That is, there will continue to be little or no fossil evidence found to support Evolutionism. Most fossil animals and plants were buried in water-laid sediments. There is no scientific proof that the fossils, the coal, or the Earth are billions of years old. There is increasing evidence that many sedimentary rocks, which some thought took thousands or millions of years to accumulate, almost certainly were deposited in only months, days, or hours.

In almost all cases, the very existence of the fossils, in the types and numbers discovered, strongly indicates catastrophic conditions were involved in the burial and preservation of these animal and plant remains. Without such conditions, there seems to be no plausible way to explain their existence.

How are rocks and fossils dated?

Originally published in Journal of Creation 14, no 1 April dating the fossil record worksheet answers The reality of the geologic column is predicated on the belief deaf dating australia fossils have restricted ranges in rock strata.

In actuality, as more and more fossils are found, the ranges of fossils keep increasing.

Carbon dating is a method, based on unprovable assumptions about the past, used to date things that contain carbon (e.g. fossils). It can only give maximum ages of around 50, years and yet C has been found in fossils and diamonds thought to be millions and billions of years old respectively.

Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age. Scientists also use direct evidence from observations of the rock layers themselves to help determine the relative age of rock layers. Specific rock formations are indicative of a particular type of environment existing when the rock was being formed. For example, most limestones represent marine environments, whereas, sandstones with ripple marks might indicate a shoreline habitat or a riverbed.

The study and comparison of exposed rock layers or strata in various parts of the earth led scientists in the early 19th century to propose that the rock layers could be correlated from place to place. Locally, physical characteristics of rocks can be compared and correlated. On a larger scale, even between continents, fossil evidence can help in correlating rock layers.

The Law of Superposition, which states that in an undisturbed horizontal sequence of rocks, the oldest rock layers will be on the bottom, with successively younger rocks on top of these, helps geologists correlate rock layers around the world. This also means that fossils found in the lowest levels in a sequence of layered rocks represent the oldest record of life there. By matching partial sequences, the truly oldest layers with fossils can be worked out.

By correlating fossils from various parts of the world, scientists are able to give relative ages to particular strata. This is called relative dating. Relative dating tells scientists if a rock layer is “older” or “younger” than another. This would also mean that fossils found in the deepest layer of rocks in an area would represent the oldest forms of life in that particular rock formation.

Explain why both relative dating and absolute dating are necessary to develop the fossil record.

Dating the Fossil Record Activity. Record the samples in order from bottom to top oldest to youngest in. Write an X in the appropriate column to indicate which fossil or fossils are present in each sample.

Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.

Primary source references As a preface to this document, I want to point out that it is a shame that we have to continue to refute the same arguments that evolutionists keep bringing up over and over again in their attempts to argue against the fact of creation, which fact has been well established since the day the earth was created ex nihilo several thousand years ago.

It is also a shame that the masses have bought all this based on some circular reasoning about fossils, where fossils tend to be found buried, similarities between various life forms, the presence of certain decay products in rocks, and other inherently speculative arguments about the past, based on phenomena that exist in the present. If I hope to accomplish anything, it will be to simply encourage critical thinking.

One must get past the arguments ad populum that its popularity counts for something , ad hominem that if you attack the person making the argument, this counts for something , and especially ad baculum that there are people who have the clout to decree it as true , to ask the key questions and challenge the unsubstantiated assumptions and thinking of those who would hold to the evolution position.

Today there are an increasing number of anti-creationist authors who are producing books and periodicals that make this relatively brief presentation insufficient to deal with all the points in dispute. Those defending creation today who don’t have the time to devote their life’s study to gaining expertise in all fields of inquiry must principally be prepared to think critically, logically, and challenge unsubstantiated assumptions made by these people.

They must also keep a level head in the face of some vicious attacks and diatribes that will be directed against them, as is advised in the scriptures 1 Peter 3: By way of definitions, I want to point out that when I speak of “evolution,” I am referring to the popular contemporary use of the word, which in a nutshell is the belief that all life forms are related by ancestry, and that the first life form occurred spontaneously, all due to completely natural processes. When I speak of “creation,” I am referring to the inherently obvious fact that the origin of all life forms can be attributed to a creator who purposefully created them with planning and intent, and the documented fact that this occurred over the course of a week’s time several thousand years ago.

This document is not a scientific thesis, but an apologetic intended to be submitted and defended by me in an interactive, online electronic forum. I claim no copyright on this document, and grant its use to the public domain.

A trace fossil is the remains of the activity of an animal rather than the remains of a part of the body. Footprints, burrows, trails, and coprolites are examples of trace fossils. Trace fossils tell us information about how animals lived in general. They can sometimes give very specific information about how fast an animal moved or what it ate. By identifying the fossils and combining this data with known preferences, palaeoclimates can be reconstructed. Non-biting midges as an example Non-biting midges, also known as chironomids, larvae are a good example of how palaeoclimates can be reconstructed using sub fossils.

Articles home page Creation vs. Evolution 0. Introduction and table of contents The following is an organized presentation on the creation vs. evolution controversy.

What about the fact that the “simple” organisms are buried in the lower levels and the more “complicated” ones are buried in the higher levels? Doesn’t this fact support the notion that simple organisms evolved into more and more complex organisms over time, with the more complex organisms buried and fossilized above the earlier and simpler life forms? Certainly this seems like a very logical assumption. But, things just aren’t that easy. There are a number of potential problems with this interpretation of the fossil record.

For example, it is interesting to note that some general kinds of fossilized creatures are very generally found in the same relative vertical orientation, with respect to each other in the fossil record, that they would have naturally been found in during life. Single celled organisms make their first appearance in the lowest layers followed by multicelled ocean bottom-dwelling creatures like sponges and worms etc.

Higher up come creatures like bony fishes, then land plants and animals, then birds and larger land animals. Of course, this is a very general pattern and does not explain why certain creatures that lived on the bottoms of oceans, like trilobites, make their first appearance in the Cambrian Ma while other creatures that live on ocean bottoms, like crabs and lobsters, don’t appear until the beginning of the Cretaceous Ma.

If the geologic column truly represents a series of closely spaced catastrophic burial events instead of long ages of time, how can this feature be explained? Certainly this seems like a difficult and rather mysterious problem for those, like myself, who might think to question the long age notion of the fossil record. At least a partial explanation might be found in the fairly recently discovered fact that at least some nested hierarchical patterns to the distribution of different populations both living and within the fossil record seem to be strongly related to ecological and population-size factors.

DOES RADIOMETRIC DATING WORK?

One of the scientists who found the tissue and published a paper on it in the peer-reviewed literature 1 Mark Armitage was subsequently fired from his position at California State University Northridge. He has sued the university , claiming that he was fired because of his religious views. Instead, this update is about the fossil itself. Samples from the fossil were sent to Dr.

Which of the following is not a manmade cause of global warming? a. burning fossil fuels b. deforestation c. respiration d. population growth user: which of the following practices that are needed to run a nuclear power plant has a negative impact on both air and water?

Rating Newest Oldest Best Answer: It is presumptuous to think Christians would claim the devil did it. It shows you probably wont take our answers seriously. But I will give mine for the fun of it. The majority of the fossil record happened during the world wide flood. You will see there are few primary things required for fossilization. Rapid burial, and rapid pressure, Fossils are formed the majority of the time during floods. We find sea creatures fossilised on the tops of mountians sugesting at one point the mountians where lower and covered in wated.

If identical fossils were found in two widely separated rock layers, it could mean that the two rock layers A. In the drawing below which layer is probably the oldest? Look at the diagram below to answer the following two questions. In which sequence are the rock layers listed in order from oldest to youngest? Based on the given rock and fossil evidence in the diagram above, which two letters most likely indicate parts of the same layer?

Using the diagram, select the choice that places the four events in their correct order. Layers 1 – 4 are folded. Unconformity below layer 6. Layers 1 – 4 are deposited. Layers 6 – 8 are deposited. What is the relative age of a fault that cuts across many rock layers? The fault is older than all the layers it cuts across.

Fossil Record

It is a trick question. You cannot do it. There is no convincing someone who has his mind made up already. But sometimes, it is even worse. Sometimes, when you point out a fossil that falls into the middle of a gap and is a superb morphological and chronological intermediate, you are met with the response: You are losing ground!

Originally published in Journal of Creation 14, no 1 April Abstract The reality of the geologic column is predicated on the belief that fossils have restricted ranges in rock strata. Shop Now Summary In actuality, as more and more fossils are found, the ranges of fossils keep increasing. I provide a few recent examples of this, and then show that stratigraphic-range extension is not the exception but the rule.

The constant extension of ranges simultaneously reduces the credibility of the geologic column and organic evolution, and makes it easier for the Genesis Flood to explain an increasingly-random fossil record. Different kinds of fossils do not occur randomly. Instead, they tend to be found at specific horizons, and these horizons can be located in rocks all over the world. For example, the evolutionist asks us why a layer of rock containing trilobites is never found to contain dinosaurs, and why a layer with dinosaurs is always found above one with trilobites and never the reverse.

Fossil succession can be viewed in terms of solitary fossils, commonly called index fossils. Otherwise, groups of fossils can be used. These are often called fossil assemblages or assemblage zones. The essence of fossil succession, however, remains the same whether individual fossils, of groups of them, are used. For approximately the last two hundred years, this succession of fossils in sedimentary rock has been used to argue that the earth has undergone successive events.

chapter 17 – The fossil record

Tiny pores on plant leaves and needles called stomata regulate carbon dioxide absorption and water vapor release. Stomata numbers decrease during times of high atmospheric CO2, and increase when atmospheric CO2 is low. The SI-CO2 relationship varies according to plant species, habitat altitude, and other factors. Correlation charts are constructed using modern plant specimens by determining their SI numbers and corresponding CO2 concentrations.

When SI and CO2 ranges are fully characterized for a plant species, the charts are used as to estimate CO2 levels for related species in the geologic past. To determine plant age Carbon14 methods are usually used to about 40, years ago.

Sunday, August 21, I teach a course on 1 Corinthians at the seminary, have used the commentaries you cite as textbooks, and have more familiarity with the literature generally than you do. Partaking in sexual immorality most certainly does have to do with paganism. It has to do, at least in part, with a return to the immoral lifestyles out of which they emerged, though Paul admits in the case of incest they are even outdoing the pagans in immorality.

Paul repeatedly warns Gentile converts in all his letters not to live as they once lived as Gentiles who did not know God. In 1 Thess 4, Gal 5, 1 Cor , 2 Cor 12, Romans 1, 6, 8, 13 , not to mention texts in Col 3 , Eph , and the Pastoral Epistles, Paul repeatedly states that if believers adopt again their old Gentile practices, especially sexually immoral practices, they will not inherit the kingdom of God.
