Tagish Lake Research Paper

Large amounts of iridium – a chemical element that is not a part of the Earth’s crust composition – were originally found in rocks of Europe and United States, and have been found everywhere ever since. Iridium, common in meteorites, is a testable evidence of the disaster hypothesis. Gould continues that the Cretaceous debacle, which is one of five episodes of mass dying, occurred at the same time as the large comet might have smashed into the Earth. The author believes this is not merely a coincidence, rather, it is a proof of the cause-effect relationship. The demise of a wide range of habitats along with the extinction of dinosaurs gives an inestimable advantage to the disaster theory over other claims, the author adds. The comet struck the Earth, and habitats, from terrestrial to marine, died with geological suddenness. Finally, this hypothesis has had an impact on the study of an atomic war and its consequences. A nuclear war, Gould says, may cause a huge drop in temperatures and result in the extinction of humanity. Testable evidence, study, development, contribution – all this makes good science.

At the beginning of the passage, he tells the readers that two of these theories are speculation and the other is pure science but each one is hard to dismiss. Testicular malfunction, the first example, cannot provide enough evidence to support this theory, solely because a paleontologist cannot extract samples and information from a fossil and simply because testicles do not fossilize. The scientists proving this theory, E. H. Colbert for an example, admitted that testicular malfunction is just a hypothesis. Therefore, Gould believes that this theory is merely unusable, but not as disadvantageous as psychoactive overdosing. Drug overdosing, like sex, can not be tested because again, like testicles, livers do not fossilize. In addition, there is also not enough evidence to prove this theory explicable, thus becoming another speculation proposal. Consequently, the theory of asteroidal zapping is the exponential scientific reasoning for dinosaur extinction. This theory can be proven by Luis and Walter Alvarez, a father-son geologist team, who became the first to propose the idea of asteroidal collision. The father and son duo collected sediment samples from deep in the Earth’s core in which they found extremely high amounts of iridium. Iridium is a highly testable chemical, therefore allowing the theory of asteroid and earth collision to be plausible. Gould’s final analysis proposes that asteroidal collision is the most scientific theory among the three. The author believes the asteroid colliding with earth and changing its temperatures allowed for evolution to happen. In summary, Gould distinctly and carefully analyzes the three theories, showing his reasoning for his scientific

Impact craters are geologic structures formed when a large meteorite, asteroid or comet smashes in to a planet or a satellite. Meteorites are small rocks in space that hit the earth's atmosphere at a high velocity. Throughout their history they have heavily bombarded all the inner bodies in our solar system. In this experiment we will use marbles as our meteorites, these will be free falling objects that will be used to copy an asteroid impact. The surfaces of the Moon, Mars and Mercury, where other geologic processes stopped millions of years ago, record this bombardment clearly. On the Earth, however, which has been

One of Barry Counties most visited and largest lakes is none other than Gun Lake. The lakefront is home to a deep Indian history that reflects the extensive development of the surrounding area over the years. The lake is a key area in Barry County for recreation and tourism, but its rich history is its most important aspect.

The city of Gem Lake, Minnesota shares much of its history with the larger, surrounding cities of White Bear Lake and Little Canada. Originally a wooded land covered with lakes, the area now known today as Gem Lake remained uncolonized until the 1840s. As early as 1843, French explorer Jean Nicollet drew a map depicting “Bear’s Lake.” This was the first record of the present day area, and it would signify the impending colonization.

Blue Mountain Lake is a rural hamlet in the Town of Indian Lake of Hamilton County, New York located at the intersection of New York Routes 28 and 30. Blue Mountain Lake also refers to the lake on the banks of which the hamlet is situated. Blue Mountain Lake is about 90 miles (140 km) north of Utica, New York and about 90 miles (140 km) northwest from Albany, New York. The place is named after the mountain peak, Blue

The sedimentary layers of rock and soil are used by the evolutionists to argue that the layers of rock would have gradually built up over millions of years. Paul D. Ackerman in his book, It’s a Young World After All: Exciting Evidences for Recent Creation, argues that if it took millions of years to build the rock layers found in the Grand Canyon, then scientists should be able to encounter countless numbers of meteors. “With the passage of vast amounts of evolutionary time, these accumulating meteorites would be incorporated into the geologic column, and there should be many of them contained in the rock layers today.” Geologists should be coming across chunks or at least pieces of meteors when digging or observing the layers. However, they do not; which means that there must have been a catastrophic event that laid down the geologic column quickly. This would explain why there are not any indications of meteors in the geological column. Ackerman ends the chapter with a clear cut conclusion: “What do the data show? A clear result in favor of a recent creation. One survey of the literature a few years ago failed to turn up a single case of a meteorite being found in the geologic column. The meteorite clock reads clearly to the effect that the earth is not very old.”

Bradbury’s (1967) dissertation research was the first comprehensive study of Zuni Salt Lake maar. Based on a radiocarbon age of 22.9 ± 1.4 ka 14C yr BP (Haynes et al., 1967) on aquatic, calcareous algae from Zuni Salt Lake lacustrine deposits 15 m above the present lake level, he concluded that the Zuni Salt Lake maar formed during the late Pleistocene. This single date provided a maximum age for the Zuni Salt Lake maar but has long been viewed as suspect because of probable hardwater carbon-reservoir effects. Subsequent argon dating of Zuni Salt Lake volcanic rocks resulted in low-resolution plateau ages of 114 ± 38 ka and 86 ± 31 ka (McIntosh and Cather, 1994).

Dealing with flooding has been an all too often occurrence for those who live or work around the western suburbs of Chicago. Parking lots are often underwater making them unsafe to enter and effectively shutting down the Schools and businesses in the area. Standing water is found around every corner causing roads to become barricaded off. I have personally watched cars floating down the street. Finally, the local residents and governments have had enough, they've reached a decision. One of the parks in the area will be torn down to make room for an emergency runoff pond. The chosen park is Armstrong Park, which includes the natural walking path park called Lake George. Adding the runoff pond will vastly improve the surrounding communities

About 7,700 years ago, Mount Mazama erupted on itself after building upon itself and reaching an impressive height of 12,000 feet. The aftermath of the collapse left a crater more than 2000 feet deep and 6 miles wide (Reichmann)! The rocks and minerals from the Mount Mazama

This research will be about concern about the pollution of Lake Macatawa, in Holland Michigan, which is leading to a clean-up effort. Preliminary research has led me to a lot of information through government regulations and newspaper articles. Because the funding for the cleanup of this lake will be done with public money, it makes sense that it would be discussed in the local paper, The Holland Sentinel. The Sentinel has a few stories, both about the cleanup through public funds, and the stories that began to rise a little bit more recently, the funding through private donations.

The Cretaceous-Paleogene boundary that occurred around 65 million years ago marks one of the three largest mass extinctions in the past 500 million years. The hypotheses of Cretaceous-Tertiary boundary impact on Yucatán Peninsula, Mexico shows evidence in the Gulf of Mexico of turbidity currents, and giant waves occurring because of the impact. There is also other evidence that impact ejecta were distributed all over the world. The mineral that was ejected during this impact was iridium. Iridium is a mineral that is commonly used to indicate a rock layer from the K-T boundary. Iridium is only found naturally on extraterrestrial bodies. In addition to Iridium, shocked quartz is used to indicate the K-T boundary. Shocked quartz is unique and

Analysis of the Murchison meteorite revealed many amino acids, the building blocks of proteins. The Murchison meteorite provided evidence that organic molecules can be formed outside the

asteroids, meteors, etc, life forms on Earth could have developed as a result of unintentional microorganism contamination. This idea implies that microorganisms can successfully survive in space, and if subjected randomly to ideal conditions evolution can occur. Evidence for this theory is also relatively strong as tests done on the Murchison meteorite which fell near Murchison, Australia in 1969 revealed it contained over 90 different amino acids (among which nineteen are found in Earth life). Although Panspermia does not directly explain the origin of all life (only its distribution) the synthesis of microorganisms in space could also be justified. If certain compounds were subjected to conditions similar to those of the Miller-Urey experiment, ultraviolet light could be substituted for lightning as a chemical reaction

Surprisingly, the clay held almost 30 times more iridium than the limestone layers above and below the clay. Similar layers in other parts of the world gave the same results. The conclusion was that a giant meteorite hit the Earth 65 million years ago and had released a large
