A look at the Inner Earth Studying the earth’s interior can help us to understand earthquakes‚ volcanoes‚ plate tectonics and more about the inner earth’s natural processes. In general the earth’s interior has been sorted by Gravity. Heavier elements like iron tend to sink toward the center or core of the earth. Lighter materials‚ the silicates‚ oxygen compounds and water have risen to become part of the crust. This action has created distinct layers within the earth and is still in process today

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

Use the Internet or textbooks to research geologists’ findings. The diagram below shows a cutaway view of the earth (not to scale). Identify each layer and describe its general characteristics.

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

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

“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
