Kuban last revised Jan. I use this format to avoid webbot spamming Fig. Brown’s website and book showing what he calls the “Rupture Phase of the Flood” Introduction Walter Brown, a young-earth creationist and retired mechanical engineer, has developed a “Flood model”1 which he believes accounts for virtually all geologic evidence on earth, as well as a variety of astronomical phenomena.

His central thesis is that only a few thousand years ago the Earth’s entire crust consisted of a granite slab 20 to 60 miles thick until recently, claimed to be 10 mi thick , suspended over a large reservoir of highly pressurized water. According to Brown, due to centuries of “tidal pumping” from the Moon’s gravity, the crust suddenly cracked and burst open, violently releasing the subterranean water and flooding the entire earth Fig.

He argues that large masses of rock and water were ejected into outer space during this massive eruption, creating all the asteroids, comets, and meteoroids in our solar system. He further claims that the immense slabs of broken crust, which he calls “hydroplates,” undulated, heaved and slid thousands of miles in a matter of months or less, and then crashed into each other to form mountains within hours. Brown presented early versions of the model during the ‘s Brown, , and subsequently revised and expanded it into a more comprehensive model of earth history, which he described in a book entitled In the Beginning: Compelling Evidence for Creation and the Flood, now in its 8th edition Brown, He provides updates and excerpts of large portions of his book at his Creationscience.

Can science prove the age of the earth? No scientific method can prove the age of the earth and the universe, and that includes the ones we have listed here. Further, it has to be assumed that the clock was never disturbed. There is no independent natural clock against which those assumptions can be tested. For example, the amount of cratering on the moon, based on currently observed cratering rates, would suggest that the moon is quite old.

However, to draw this conclusion we have to assume that the rate of cratering has been the same in the past as it is now.

Geologic Timing Is Everything! Geologic Timing is Everything! Introduction The words slide off the tongue—Earth was formed from a cloud of hot gas and dust 4. But how long is that? One of the most difficult things for the human brain to comprehend is the scope of geologic time because it is impossible to visualize the magnitude of numbers like a million or billion.

Though distorted in the details, many of these stories seem to reflect the true account in Genesis 6—9. This fascination is also bringing people in droves from around the globe to the life-sized Ark replica at the Ark Encounter in northern Kentucky. At the same time, several teams have continued searching for the real Ark. Most of them have focused on Mount Ararat in northeastern Turkey, where eyewitness accounts of a wooden structure have spurred interest for centuries.

This was a region, not a single mountain. How were the rocks and strata in this region formed and changed during the Flood and in the years afterward? Since the s, several dozen expeditions have scaled Mt.

At the time that Darwin’s On the Origin of Species was published, the earth was “scientifically” determined to be million years old. By , it was found to be 1. In , science firmly established that the earth was 3. Finally in , it was discovered that the earth is “really” 4.

A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation for example, the large muscles of a weightlifter. Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment. Also used to describe the process of genetic change within a population, as influenced by natural selection.

A graph of the average fitness of a population in relation to the frequencies of genotypes in it. Peaks on the landscape correspond to genotypic frequencies at which the average fitness is high, valleys to genotypic frequencies at which the average fitness is low. Also called a fitness surface. A behavior has adaptive logic if it tends to increase the number of offspring that an individual contributes to the next and following generations.

If such a behavior is even partly genetically determined, it will tend to become widespread in the population.

By Mazuk The principle of superposition builds on the principle of original horizontality. Most scientists today believe that life has existed on the earth for billions of years. In step 2, students can investigate the role of brittle vs ductile environments in relation to compressional, tensional, and shear stresses.

In Part A this activity, you will investigate the scope of geologic time by creating a timeline that marks major geologic and biological events over the billion year existence of planet Earth.

After mating, the female then builds a nest elsewhere to raise the young alone. Franco Atirador Stephen J. Gould argued that these enormous antlers, which required great mineral resources from plants to support and prevented the elk from navigating through forests, were largely responsible for their extinction. The positioning of the antlers were poor for combat between males, but were great for intimidating rivals and impressing females.

Consider also the most popular explanation offered for the photo right , that a concretion formed around an s-era hammer as minerals precipitated out of the surrounding limestone. From Adam until Real Science Radio , in only generations! Another paper, in the American Journal of Physical Anthropology Eugenie Scott ‘s own field on High mitochondrial mutation rates , shows that one mitochondrial DNA mutation occurs every other generation, which, as creationists point out , indicates that mtEve would have lived about generations ago.

Two Primary Means of Dating Rocks. 1) Relative Dating Determines the temporal order of rock forming events Does not give numeric ages Use of stratigraphic principles and fossils.

The Oldest Living Thing: The oldest living thing on earth is either an Irish Oak or a Bristlecone pine. If we assume a growth rate of one tree ring per year, then the oldest trees are between 4, and 4, years old. Also, with regard to fossil tree rings, the author has been unable to find any documented instances of fossil trees having more than about rings. This is significant since we are told that God literally made the Earth, and all that is in it, only about years before the Noachian Flood described in the Book of Genesis.

In a Bristlecone Pine tree was discovered that has just over 5, tree rings. Helium in the Atmosphere: Helium is a byproduct of the radioactive decay of uranium as it decays into various different elements into its final stable element: As it decays, the helium not only accumulates in the rocks themselves, but also escapes from them and accumulates in the earth’s atmosphere. They also know how much helium is currently in the atmosphere.

Opt out or contact us anytime In a presentation at the conference, Wise showed a slide of a fossil sequence that moved from reptile to mammal, with some transitional fossils in between. He veered suddenly from his usual hyperactive mode to contemplative. Wise is refining a theory, for example, that the order reflects how far the animals lived from the shore, so those living farthest from the water show up last in the record. We have lines of possibility that we continue to advance but at the same time we recognize that this is science, so the explanations are subject to change with new discoveries.

His answer confirmed him as the product of the postmodern university, where truth is dependent on the framework: But if the parameter is different, portions of it could be completely in error. The theory is the first attempt to describe the mechanism of the flood. A computer model refining the theory purports to show an earth wobbling crazily on its axis as land masses come together and then break apart, forming the continents we have today.

So which side did he choose? Everybody has moments of doubt. But I can have those moments without my brain exploding. But they have become a burden to many geologists at Christian colleges around the country.

Relative Dating

The way it really is: Even the way dates are reported e. However, although we can measure many things about a rock, we cannot directly measure its age. For example, we can measure its mass, its volume, its colour, the minerals in it, their size and the way they are arranged. We can crush the rock and measure its chemical composition and the radioactive elements it contains.

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.
