Part 1 This diagram was similar to one Alfred Wegener drew to show the distribution of continents 300 million years ago. His theory of continental drift was met with skepticism in the scientific community. [pic] 1. Describe three forms of evidence Wegener used to support his ideas of continental drift. Wegener used landorms, climate, and fossils to support his theory of continental drift. He said that when it came to landforms all the continents seemed to fit like a “jigsaw puzzle”. Even went as as far to say the mountain ranges seemed to line up as well. Wegener said that the same fossils and rock from one continent would end up on a different continent. For instance a fossil found in Africa would also be found in South America. When it came to climate, Wegener said that some fossils did not match the climate. For instance, there a glacier scratches in South Africa. 2. Years later, the continental drift theory reemerged as plate tectonic theory, with two additional pieces of evidence. [pic] [pic] Refer to the images above. Discuss in detail the two pieces of additional evidence that supported Wegener’s theory, now known as the theory of plate tectonics.

...Associate Level Material History of Rock Worksheet Leah Bechtel 12/09/2012 SCI/245 Robert Dillon Write a 500- to 750-word explanation regarding the role of plate tectonics in the origin of igneous rocks. The role of plate tectonics in the origin of igneous rock is extremely important. Igneous rock is formed from magma that reaches the continental and oceanic crust or through hot spots that are around the world. There are three different places where igneous rocks can form; where the lithospheric plates pull apart at mid ocean ridges, where plates come together at seduction zones, and where continental crust is pushed together making the crust thicker and allowing it to heat to a melting point. The word igneous comes from the Latin word for fire, igneous rocks start off as a hot, fluid material which is usually erupted from the Earth’s surface as lava, or magma at shallow depths or deep depths. Magma is a mush like material that can carry a load of minerals, but people often think of lava and magma as a liquid like material of molten metals. The three types of igneous rocks are extrusive, intrusive and platonic rocks. Extrusive rocks are rocks that form and cool on the crust of the Earth whether it is on the continental crust or the oceanic crust. Extrusive rocks cool quickly, within a few seconds to months and they have invisible or very small grains; extrusive rocks have an aphanitic texture. Intrusive rocks are rocks that form within already existing rocks causing...

...Associate Level Material Sedimentary Rock Worksheet Use the following table to describe and distinguish between the effects of weathering and erosion. Each response must be at least 200 words. Effects of Weathering Effects of Erosion What are the Differences? Mechanical or physical weathering includes two main processes: fracturing and abrasion, which may be intense in wet and dry regions. Wind, rain, snow, ice and other geological events cause mechanical weathering. This type of weathering leads to splitting of rocks and minerals into fragments. Big and sudden changes in air temperature, which are very common in deserts or water temperature changes, always cause expansion or contraction of minerals. For example, when water enters a crack and freezes, it widens the crack and eventually leads to breaking of the surface. Plant roots have a similar effect when they grow so big that they reach the crack in the rock. At some point, the rock will fall apart. This type of weathering changes the mineral composition of rocks by chemical processes and it can sometimes lead to dangerous conditions. Water is the basic agent in chemical weathering because it initiates the whole process. Some of its effects are oxidation (rusting), hydration and carbonization. Chemical weathering also causes loss of chemical elements by solution in water. Caves, stalactites and stalagmites are created by different chemical processes of weathering Sheet erosion is soil movement from raindrop...

...Shake and Erupt: A critical reflection on teaching earthquakes and volcanoes to KS3 Rationale: Perhaps the most dynamic features of the Earth’s awesome power and nature are when Volcanoes and Earthquakes occur. Their workings are at the very core of our planet’s history and their unpredictable activity continues to shake mankind’s understanding of the planet. This topic or scheme of work for my mixed ability year nine class offers a plethora of attributes that both incorporates sound core Geographic knowledge and divers teaching formats that can present a degree of awe and wonder into the minds of young people. Planning and teaching such a topic at a time when the Geography National Curriculum is being reviewed by the new coalition Government, seems to provide somewhat of a blank canvass as to what pedagogical approaches might be the most appropriate to adopt. Whatever the NC will look like, we are led to believe that there will be a re-focus on the ‘core’ knowledge in subjects like Geography. This is not to say a return to didactic teaching where teachers are merely transmitters of information, or indeed to adopt a textbook pedagogy which is reminiscent of the late 1970s and 1980s. The Geography Curriculum Consultation Full Report makes it clear “That a line-by-line, detailed list of geography’s contents is not the best way to draw a positive response from teachers . . . though there is strong support for the national curriculum achieving greater clarity over the core...

...Exploring Taiwan---Taiwan Is Alive How does it feel like to live on a floating plate, unaware of probable earthquakes and tectonic movements? I understood how it feels like because I live in Taiwan! After an introduction to the geology of Taiwan, I found Taiwan a really active and dynamic island. This reminded me of an article I read on New York Times years ago; it titled: Taiwan Moves Closer to Mainland, Pulled by Forces That Molded Its Mountains. In the article, there were a research team built by three groups of geologists from three countries—Taiwan, United States of America and Japan. In order to learn the process of mountain building on Taiwan islands, they used seismic monitoring device and computer graphing to track the movement of tectonic plates. Such research found one of the facts that Taiwan is actually moving closer to Mainland China! Not to mention that Taiwan is growing taller and taller where our mountains has been rising above sea levels since 60 million years ago. I cannot help but wonder if Taiwan Island would join the Eurasia millions years after! Despite my fantasy of walking across Taiwan Strait to Eurasia many years after, it is amazing to learn that there are actually “underground” forces pushing and pulling Taiwan islands by millimeters every second. The most apparent connection between these forces and our lives on the island is earthquakes and volcanic activity. First, through my life until now, I have experienced at least thousand times of...
