Sedimentary rock forms in layers over millions of years. If you look at a cliff made from sedimentary rock, you’ll notice distinct layers that may even be different colors. Changes in the environment cause changes in the rocks. For example, a volcanic eruption may create a layer made of hardened ash. The oldest layers of rock are at the bottom. Newer layers are at the top. All about Layers of Rocks Fun Science Facts for Kids Image of Layered Sedimentary RocksSometimes, the layers are twisted or tilted because of the movement of the Earth’s tectonic plates. Rocks on a fault line may snap or break.Gizmodo online Dating Profile
Unreliability of Radiometric Dating and Old Age of the Earth
Scientists study these layers to learn more about the Earth’s history. Radiometric dating measures radioactive elements in the rocks. Scientists can learn exactly how old a rock is by using radiometric dating.

Com/all-about-layers-of-rocks/ Learn about the oldest rocks found in the parks that range in age from 8 billion to 655 million years old. Fossils are found in the rocks, museum collections, and cultural contexts of more than 765 National Park Service areas and span every period of geologic time from billion-year-old stromatolites to Ice Age mammals that lived a few thousand years ago. Visit the parks that preserve fossils from each major time period. Have you ever wondered how geologic time works? This interactive classroom learning activity helps build the basic understanding of geologic time for grades 9-9. Every park contains a slice of geologic time. In this classroom resource we highlight a few parks associated with each geologic time period. Using a simple three or four generation family tree, students will construct a relatives time tree that mimics the major divisions of the geologic time scale (Precambrian, Paleozoic, Mesozoic, and Cenozoic). For Grades 9-67. Read about the age of the Universe and Earth while learning how scientists determine geologic age through Radiometic Dating. You will also be recieving a free copy of Codes and Creation CMI\'s by Calvin Smith in your inbox. There is no doubt that it is an important question and stratigraphic locations abound. One of the most popular locations is the K/T boundary.

Evidence has been presented to support that choice, one of which is a change from worldwide/continental to local/regional sedimentation. However, a close analysis of this evidence suggests that it raises more questions than it answers, supporting the idea that the end of the Flood corresponds to the Late Cenozoic. Creationists have shown that geological and paleontological observations are congruent with the Genesis Flood and problematic for secular natural history. Uniformitarian 6 scientists cannot explain or ignore an increasing number of phenomena that contradict their interpretations, such as the lateral extent of many strata and the absence of erosion between layers. 7-9 In addition, many creationists are constructing comprehensive models to explain the Flood, for example Brown 5, 6 Budd 7 Hunter 8 Oard 9 Setterfield and Setterfield 65 Tyler 66 and Wise et al. 67Disdaining creationism, secular scientists seem unaware of much of this work. For instance, in a new book critical of biblical history, a recent creation, a global flood, and the accounts of Genesis, Young and Stearley 68 misstate much about creationism and Flood geology, seemingly content with straw men of their own devising to fill its many pages. 69 The theory then rapidly rises to a position of control in the processes of the mind and observation, [and then] induction and interpretation are guided by it. From an unduly favored child it readily grows to be a master and leads its author withersoever it will. 66Flood geology is nowhere near the advancement of uniformitarian geology at Chamberlin s time. Thousands of geologists and large amounts of money had taken the science from the gentleman amateurs of the early 6855s to a position of influence in academia and society. Thus, we must be even more careful of ruling hypotheses that distract from important questions and investigations. So, those proposing hypotheses or models must accept the professional give and take that should mark science, much less science done by Christians. I encourage the development of ideas, but not the tendency to reject criticism and questioning. This is an application of what the Bible calls iron sharpening iron and will promote progress that will be otherwise retarded by ruling theories. Given this methodological approach, I wish to examine the location of the post-Flood boundary. I must first acknowledge opposition to the often-unspoken assumption that the geological time scale is the metric for arguing this boundary.
Three positions were argued in Reed and Oard: 67the geological time scale represents a correct chronostratigraphic (relative) arrangement of the rock record, 68it is an anti-biblical template not useful to diluvial research because it uses time as its stratigraphic key, 69 andThe third position is mine, and I believe it to be a middle ground between the two, based on field evidence I have studied. For more information, I recommend reading the cited literature. For those who choose to use the time scale as at least an approximate yardstick, there are three major proposals for the post-Flood boundary (figure 6). 78 77Creationists are interested in identifying the post-Flood boundary for several reasons. Perhaps the most important is to show the presence of the Flood in the rock record to those who do not believe it ever occurred. These include uniformitarians, theistic evolutionists, and other old-earth creationists. Many of these people believe there is little or no evidence for the Flood. For example, anti-creationist geologist, Arthur Strahler proclaimed: Strahler at least grudgingly admits we have a little evidence. But, the Christian geologist, Davis Young, now retired as a geology professor from Calvin College, is surprisingly less generous: there is no geological evidence to confirm the idea of a universal deluge. In addition to these apologetic reasons, the boundary constrains the part of the rock record caused by the Flood, a crucial component of any Flood model. Third, it also allows a geologically-based understanding of post-Flood processes and events, providing a context for the times between the Flood and the founding of the Mesopotamian empires, which can be forensically studied by archaeology. Among creationists, the question of the extent, nature, and severity of post-Flood catastrophes is a question that continues to be debated. On the other side of this stratigraphic boundary is information about late-Flood processes and events, which can provide understanding about the nature of the changes during that time. Fourth, the timing of the end of the Flood helps us understand the approximate number of animals that formed the faunal baseline for later diversification and migration.
For example, if the correct location is the K/T boundary, the Tertiary would include sediments and fossils laid down after the Flood. Given the extent and thickness of some of these deposits, it would have been a time of waning catastrophes. Tertiary fossils show a great variety of mammals all across the planet, requiring a model for the fecund repopulation and rapid spread of these animals immediately after the Flood. 77 If the correct location is in the Late Cenozoic, then the paleontological evidence would suggest a slower and less dramatic post-Flood diversification. The number of animals spreading out from the mountains of Ararat would need to be explained only by the variety we see today and during the Ice Age. 85 Thus, the boundary placement affects the burgeoning subfield of baraminology. A fifth reason is the timing of the Ice Age. Did it begin immediately after the Flood in favorable locations, such as the mountains of Scandinavia, eastern and central Canada, the Greenland mountains, and Antarctica, or was it delayed for several centuries by large-scale post-Flood catastrophism? 86 Would it have been possible on a globally warm post-Flood Earth to delay the Ice Age, as shown by Cenozoic fossils at high latitudes? 87-89Sixth, since the boundary placement is foundational to developing Flood models, effort may be wasted if the location is not known. Any creationist who assumes an incorrect boundary will likely be wrong about events after the Flood and during the late Flood period. Finally, the responsibility of teaching the truth binds creationists to try to discern as best they can the nature of the Flood, which they will teach to the church. We should remember: Examine everything carefully hold fast to that which is good (NASB). As a new creationist many years ago, I was influenced by the idea of significant post-Flood catastrophism. I accepted the Miocene Columbia River Basalts (CRBs) as post-Flood the arguments seemed valid. 85 I accepted the Pliocene dam breach hypothesis for the formation of Grand Canyon.
86, 87 If asked, I would have suggested the end of the Flood at the K/T boundary, 88 though I had not thought through the issues.
