1. Wegner’s hypothesis of continental drift using the observation that the earth’s surfaces are continually changing and other evidence was that the continents had once been joined‚ and over time had drifted apart but he couldn’t explain the mechanism behind it. 2. Evidence gathered by Ewing‚ Tharp and Hess that lead to the theory of plate tectonics was: ⦁ In the early 1950s Ewing‚ with the help of Marie Tharp‚ a cartographer‚ mapped the seafloor using available echo profiles‚ the resulting mapped

The Origin of the Earth‚ One of God’s Hidden Secrets “Much of geology is pure speculation and is as such on the same basis as philosophy‚ or must be accepted on faith‚ as the truths of theology” (Rehwinkel 177). For geologists this means that any theory of how the Earth‚ atmosphere and life originated‚ takes faith to believe‚ whether it is the evolutionist’s view or the creationist’s view. Creationists believe that the Earth was created 6000-7000 years ago. This number is based on what the Bible

of the Moon’s origin? The currently accepted hypothesis for the Moon’s origin--which is supported by chemical analysis of Moon rocks--is that it began as part of Earth but was blown off when the early Earth was struck by a Mars-sized early planet (retroactively named Theia). Huge amounts of debris were ejected into orbit around the Earth‚ where most of it coalesced into the Moon. The other moons in the solar system have different origins. The small ones are mostly captured asteroids‚ I think‚ while

“EARTH HISTORY” Geologic Time: Geology needs a time Scale: -The prime goal of the science of geology‚ is to interpreting earth history. Geological time scale- -Anordered‚internallyconsistent‚ internationally recognized sequence of time intervals‚ and record the life of Earth. Short history of geology: James Ussher(mid 1600s)- he determined that earth was only a few thousands of years old having been created in 4004 b.c Catastrophists(17-18cen.)-believed that earth landscape had been developed

AGE OF THE EARTH Scientists have settled on the age of the earth of about 4.6 billion years as a result of research started almost 50 years ago. This conclusion was based upon carefully designed and conducted experiments that compared the ratios in rock samples of parent elements to daughter elements ( some of which would have been from radioactive decay of the parent‚ some of which may have been present in the sample at the time of formation). Since radioactive decay is known to occur at a constant

Heaven on Earth Everyone has that special place where they can go to escape all the pressures and worries of life‚ that wonderful spot where you can go to soothe all your complications and stress. Imagine for a moment what that place is for you. A place that makes you feel complete and captivated. For me‚ the beach is that ultimate place that is unlike any other I have ever experienced.

Surface Tension Properties of Liquids Introduction The purpose of this experiment is to measure and record the surface tension of water and other aqueous solutions using capillary rise method techniques and practicing lab safety. In this laboratory the surface tension of water depends on the concentration of the following solutes; NaCl‚ acetone‚ and sodium dodecyl sulfate (SDS). Intermolecular interactions as well as other phases (solid‚ or air) make a liquid exist. The data collected will show

Old Earth vs. New Earth Many Christian scholars are open to the belief in an old earth. One of these scholars is Colin Humphreys who believes that radioactive dating methods aren’t as accurate as most people think but they can still prove that we have a very old earth. Greg Koukl‚ is another Christian apologist‚ speaker‚ philosopher‚ and author who believes that the answer to the old earth/new earth lies in the heavens. The stars show light that takes millions of years to get to us. He argues that

Life on Earth. 1. Analysis of the oldest sedimentary rocks provides evidence for the origin of life. * Identify the relationship between the conditions on early Earth and the origin of organic molecules. * Scientists estimate that the universe is 10-20 billion years old and arose as a big bang‚ which is still expanding the universe. * The early Earth was very different from the Earth today and no oxygen was present. This means that there was no ozone layer exposing the Earth’s surface
