Laboratory Manual in Physical Geology, 5th Edition

History[ edit ] Biblical dates for creation[ edit ] The first major comprehensive draft of Genesis was composed by the Yahwist in the late 7th or the 6th century BC, during the Babylonian captivity , with later additions made by the priestly source in the post-exilic period. The poor world is almost 6, years old. In particular, discoveries in geology required an Earth that was much older than thousands of years, and proposals such as Abraham Gottlob Werner ‘s Neptunism attempted to incorporate what was understood from geological investigations into a coherent description of Earth’s natural history. James Hutton , now regarded as the father of modern geology, went further and opened up the concept of deep time for scientific inquiry. Rather than accepting that the Earth was deteriorating from a primal state, he maintained that the Earth was infinitely old. As these processes were very gradual, the Earth needed to be ancient, in order to allow time for the changes to occur. While his ideas of Plutonism were hotly contested, scientific inquiries on competing ideas of catastrophism pushed back the age of the Earth into the millions of years — still much younger than commonly accepted by modern scientists, but a great change from the literalist view of an Earth that was only a few thousand years old.

Objections to evolution

Outlook Other Abstract U-Pb radioisotope dating is now the absolute dating method of first choice among geochronologists, especially using the mineral zircon. A variety of analytical instruments have also now been developed using different micro-sampling techniques coupled with mass spectrometers, thus enabling wide usage of U-Pb radioisotope dating. However, problems remain in the interpretation of the measured Pb isotopic ratios to transform them into ages.

Among them is the presence of non-radiogenic Pb of unknown composition, often referred to as common or initial Pb. There is also primordial Pb that the earth acquired when it formed, its isotopic composition determined as that of troilite in the Canyon Diablo iron meteorite.

USGS Paleontology glossary Acritarch microscopic organic structure from any of a number of organisms; common during the Proterozoic. Adaptive radiation, evolutionary radiation the rapid expansion and diversification of a group of organisms as they fill unoccupied ecological niches , evolving into new species. Age of Mammals term found in popular books on evolutionary systematics for the Cenozoic era, beginning with the Paleocene Epoch when following the K—T end Cretaceous mass extinction , mammals underwent a huge evolutionary radiation and thus replaced reptiles as the dominant life on Earth.

The Age of Mammals has in turn been replaced by the Anthropocene or Age of Man, Holocene when humans dominate every conceivable environment and most other life forms apart from weedy species are suffering a mass extinction Yes, I know humans are also mammals, so technically speaking this is still the Age of Mammals, but I tend to think of the Age of Mammals as a period of flourishing biodiversity.

MAK Age of Reptiles term found in popular books on evolutionary systematics for the Permian through to Cretaceous periods but obviously originating with Victorian discoveries of “antediluvian monsters” , when reptiles first mammal-like reptiles , then archosaurs and marine reptiles were the dominant life on Earth. Paleontologist Edwin Colbert wrote a popular intelligent layperson book with the same title. The Age of Reptiles was followed by the Age of Mammals. The fresco sits in the Yale Peabody Museum in New Haven, Connecticut, and was completed in after three years of work.

The Age of Reptiles was at one time the largest painting in the world, and depicts a span of nearly million years in Earth’s history. Painted in the Renaissance fresco secco technique, The Age of Reptiles was an important cultural influence during the s—60s, images of which are often found in earlier books on paleontology, and was also the model for dinosaur toys.

Despite its somewhat outdated view of dinosaurs presenting them as slow, sluggish creatures , The Age of Reptiles is still notable for its historical and artistic merit and as the largest natural history painting in the world. It has been an inspiration to many visitors including both Robert Bakker and Peter Dodson , who credit it with influencing them to become paleontologists.

Dodson was nearly moved to tears upon first seeing it as a college senior.

Lab 8 dating of rocks fossils and geologic events answers Sep Explain how the radioactive decay of certain elements can be used to determine the ages of Earth materials. God would presumably be universal and timeless as well as all-knowing, as is the universe, therefore these man-written books and scriptures, are just that, man-written linguistically created nonsense used to control men and women thousands of years ago. One must consider the fact that, even now, there are religious zealots and ordinary people still entrenched in a control belief system that is so far removed from reality that it borders on madness.

The classic Miller—Urey experiment and similar research demonstrated that most amino acids, the basic chemical constituents of the proteins used in all living organisms, can be synthesized from inorganic compounds under conditions intended to replicate those of the early Earth.

The language of man follows things and imitates them; the Word of God precedes and creates them. Man speaks because things are; but these are because God hath spoken. Let Him speak again, and things will revert together with man who speaks of them, to nothing. Let us be content to perceive in creation a character which belongs only to God, and which distinguishes His work from that of His creatures.

The human mind works only with the materials with which God supplies it; it observes, imitates, combines, but does not create. The best painter in the world, composing the most beautiful picture that ever proceeded from the hand of man, creates nothing: Trace to the origin of each of the several things which have combined to form this picture, and you will find that all the channels from which they came, converge towards, and meet in the Creator, who is God. In thus showing us from its first page that the visible world has had such a wonderful beginning, the Bible informs us that it is also as a Creator that God saves souls.

He not only develops the natural dispositions of our hearts, but creates in them new ones, “For we are labourers together with God”; but labourers working like the painter, with what God has given to us. We hear, read, seek, believe, pray, but even these come from God.

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.

Are you sure that you want to delete this answer? Yes Sorry, something has gone wrong. In , the British physicist Lord Rutherford–after defining the structure of the atom– made the first clear suggestion for using radioactivity as a tool for measuring geologic time directly; shortly thereafter, in , Professor B. Boltwood, radiochemist of Yale Uniyersity, published a list of geologic ages based on radioactivity.

On the wet sand right this does not happen. The Egyptians moistened the sand over which the sledge moved. By using the right quantity of water they could halve the number of workers needed. The researchers published this discovery online on 29 April in Physical Review Letters. For the construction of the pyramids, the ancient Egyptians had to transport heavy blocks of stone and large statues across the desert.

The Egyptians therefore placed the heavy objects on a sledge that workers pulled over the sand. Research from the University of Amsterdam has now revealed that the Egyptians probably made the desert sand in front of the sledge wet. Experiments have demonstrated that the correct amount of dampness in the sand halves the pulling force required.

Firm sand The physicists placed a laboratory version of the Egyptian sledge in a tray of sand. They determined both the required pulling force and the stiffness of the sand as a function of the quantity of water in the sand. To determine the stiffness they used a rheometer, which shows how much force is needed to deform a certain volume of sand. Experiments revealed that the required pulling force decreased proportional to the stiffness of the sand.

Capillary bridges arise when water is added to the sand.
