Evidence Of The Dynamic Changes Of Earth 's Surface Through Time

The age of the earth has been debated for centuries. Many people believe in evolution that it took billions of years for everything and everyone to form. Others believe that God created the earth in seven days and that the earth is young. Secular scientist and Christian scientist both use different methods for determining how old the earth is. For example, Secular scientist look and use the layers of rocks to help them, while Christian scientist uses the Bible and look at historical data from other cultures to help them. Doesn't looking at archeological data seem more accurate than looking at rocks? If the earth is truly billions of years old, then why is there little sediment on the sea floor? Or how can secular scientist explain finding soft tissue in a fossil if the earth is old? The most logical explanation is that the earth is young. Many people believe something just because people say that it is true, sometimes it is good to investigate for yourself and see if it is good for you.

Next, these rocks undergo erosion, which is the process of moving sediments from one place to another. Then, these sediments are deposited all at one place and over time they start to converge and cement as layers which are also known as strata. As time keeps going, new sediments deposit and cement together over old ones forming new layers. This is a repetitive process that eventually build up layers to make up a Sedimentary rock. Approximately 40 major sedimentary rock layers exposed in the Grand Canyon National Park area range in age from about 200 million to nearly 2 billion years old. As you can see, sedimentary rock formation takes an excessive amount of time.

Radiometric dating is a technique that utilizes unstable isotopes of natural elements. Because these unstable isotopes eventually decay at a constant and singular rate despite any environmental changes such as temperature or moisture changes. The unit used as measurement is a half-life which is the amount of time it takes 50% of the original isotope to decay into the next isotope or daughter isotope. Basically the amount of half-lives is multiplied by the length of the half-life to estimate the age of the object being tested. Every element used has a different half-life and that makes each useful for measuring certain types of material. Some have longer a half-life and thus a longer effective dating range. Potassium-argon dating is useful for dating material that is extremely old. This method is used by geologists to replace relative ages based on rock formation with absolute ages. The dates found from the radiometric technique are accurate because the sources, the individual radioactive isotopes, are unchanging and unaffected by environmental factors. This means that the radiometric data will always be precise unlike relative dating which relies on the theory of uniformitarianism, the theory that geological history is made up of endless and uniform

Encyclopaedia Britannica also states that it is “proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old” (1998). This method of age determination is dependent upon the decay of nitrogen and radiocarbon (Carbon-14) (Encyclopaediea Britannica, 1998; Opinions of Radiocarbon Dating, 2011). Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere (Encyclopaediea Britannica, 1998; Opinions of Radiocarbon Dating, 2011) and all living things exchange the gas carbon-14 with the atmosphere surrounding them. The amount of carbon-14 exchanged into the living organism is perfectly balanced with its surroundings, but when an organism dies, they stop taking in the gas and that equilibrium is damaged. Because Carbon-14 slowly decays at a known rate called its “half-life” in a dead organism, scientists can figure out how long ago it had stopped exchanging carbon with its atmosphere. Thus, its age can be determined by measuring the amount of Carbon-14 in a sample (Hirst, 2017; Opinions of Radiocarbon Dating, 2017; Oxford Radiocarbon Accelerator Unit Research Laboratory for Archaeology, n.d.; Earthsky, 2017; Cram, 1993). With the utilisation of Radiocarbon Dating, scientists have been able to discover that Lindow

Radiometric dating is still being used today. Modern uranium-lead radioactive dating of meteorites and earth materials gives us today's estimate that the earth is about 4.5 billion years

Scientist are able to use modern instruments to accurately date these rocks by measuring radioactive decay. These rocks are approximently 1.7 billion years old, less than half the age of the earth. These black rocks tell scientist not only how old they date back but

The Grand Canyon is a plethora of geological treasures. However, the debate on how old the Grand Canyon really is continues throughout the scientific community. Between relative dating and absolute dating, which one will give a more accurate answer or will both be needed?

Geochronology is associated with geology. Geochronology deals with the absolute age dating for the rock formations. When it comes to geochronology, it also is associated with the Geologic Time Scale.

The methods used to date the various rocks in Grand Canyon fall into one of two methods: Relative dating and Absolute dating. These two methods for dating are accurately named. Since relative dating is based mostly upon paleontology and the Law of Superposition, it is a dating system which can cover a very large timespan. Also, there are a few drawbacks to it, the primary one I noticed was that the farther one goes back in time, the fewer fossils there

Dating the rocks of the Grand Canyon is a scientific way to find out the age of this mysterious landmark. The age of the Earth and the Grand Canyon is a question both of a biblical interpretation and scientific investigation. It can be viewed by an old earth creationist and young earth creationist. The two creationists have a difference of opinion concerning the formation and age of the Grand Canyon rocks.

Before the discovery of radiometric methods to determine the age of the Earth, the first few attempts were off by thousands of millions

This method is used to determine the exact age of fossils, artifacts and the earth. This involves, examining several strata of the crust of the earth to show the time intervals of one layer of rock to another layer as well as use the layering principle to confirm the series of cultures.

When we think of history, we think of important people, places, cultures, events, and much more. The backbone of history rests on its chronology. It gives us the "when" of basic analysis. It gives us a frame of reference, the order of things. Before having an "absolute" way of determining dates, history was based in guesses and assumptions. Many attempts were made to organize the dates of the past. Some of these attempts were made by geologist. Geologist used the idea of "stratigraphic succession" (Renfrew, 1973) which is based on the "principle that when successive layers or strata are observed in position, the underlying ones are the earliest." (Pg. 23 Renfrew, 1973) By setting the layers in
