He never got the credit he deserved‚ and it wasn’t until the early 1960’s when a younger generation of geologists took over and further proved seafloor spreading tectonic plates grinding across each other deep within the earth. Wegener responded with to the strong criticism the best way possible‚ by compiling additional evidence and other sources. He admitted

amount of error. Because absolute dates through radioactive dating are really only for igneous/metamorphic rocks and because heat and pressure affect the dates‚ therefore not making them absolute. 3.) In order to get an accurate numerical date‚ geologists require on average 0.5-1 grams of material. Why might this be difficult to obtain from some recent (<5‚000 years old) volcanic ashes or other thinly bedded deposits? It’s hard to collect that amount because the ash is so thin that it is easily

this work he described the idea of uniformity by saying that the same chemical‚ physical‚ and biological laws and processes that are happening today have also happened in the geological past. This was the first theory of merit for the old-Earth geologist of the day. He was directly influential to a man named Charles Lyell‚ who was inspired by Hutton’s book and went on explorations around Europe seeking evidence for the theory that over long periods of time‚ these weak geologic forces we see today

Continental drift has helped create the diversity we see present in modern day plants and animals. Through a process of speciation‚ the movement of the continents has had a generous role throughout evolution‚ effecting and distributing flora and fauna. The Earth’s continents were once one‚ a large supercontinent called Pangea that later separated into two smaller ones known as Gondwana and Laurasia. The separation and collision of continents has not only created some of the valleys and mountain ranges

PART C - Analyze and Conclude 1. After you created a geologic time scale with key events in Earth’s History‚ compare the number of events in each era. Did more Earth-shaping events occur early in Earth’s history or later on? Explain why. Based on my geologic time scale‚ there are three events in Precambrian Time‚ two events in Paleozoic Era‚ four events in Mesozoic Era and one event in Cenozoic Era. These events mostly occurred later on in Earth’s history. Mesozoic Era has the most events which

Coincidentally‚ prior to the earthquake‚ Haiti experienced two tropical storms and a major hurricane in 2010; which may corroborate geologists’ assertion that increased soil erosion from these extreme weather events may have triggered the 2010 earthquake in Haiti (Ader‚ 2011) (Wdowinski‚ Tsukanov‚ Hong‚ & Amelung‚ 2010).

Earth is changing Introduction We often think of the Earth as a stable and safe place to live. The landscape we see seems timeless and impossible to influence. At the same time‚ we know there are a lot of forces that affect our planet and change it. Some changes are quick‚ such as when earthquakes and volcanic eruptions break the ground or covering it with lava. Other changes may take millions of years‚ such as wind or the abrasive forces of water. The hunt for food‚ searching for land to cultivate
