Effects on Motion and Plate Techtonics

...Material Effects of the Motions of Tectonic Plates Worksheet From Visualizing Earth Science, by Merali, Z., and Skinner, B. J, 2009, Hoboken, NJ: Wiley. Copyright 2009 by Wiley. Adapted with permission. 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. 1. Describe three forms of evidence Wegener used to support his ideas of continental drift. • Continental Margins (Visually land masses fit together like a puzzle) • Rock layers (similarity on the coast lines as well in a different continent • Fossil evidence (How some animals were identical on the other side of the world, and how tropical plants were found in Arctic regions. 2. Years later, the continental drift theory reemerged as plate tectonic theory, with two additional pieces of evidence. 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. • One additional piece of evidence was the mapping of the ocean sea floor. When all these investigations about the ocean sea floor were given to scientist, a new light in the composition of the rocks and their distribution was discovered. Wegener's ideas started now to make sense for most geologists, the saddest part is that at this time Wegener was already dead so he could not see his vindication...

Your responses will be assessed according to the accuracy of the content. Minerals 1. How do minerals affect society? Minerals are dense, nonliving, naturally occurring substances. That have definite chemical formulas and general structure. They vary in color, solidity, crystal form, density, crystal size, transparency, location, composition, and abundance. They have many uses and purposes in society. Almost all chemical elements in the Earth's crust are associated with at least one mineral. This is how we are able to build buildings on ground and not live in floating huts.   2. What is the difference between metallic and nonmetallic minerals? Provide two examples from each category and discuss their uses. Metallic minerals are those minerals which can be melted to obtain new products. Aluminum is one of the most abundant metallic minerals on earth.  It is used in the production of automobiles, construction, electrical, machinery materials. Copper also a metallic mineral is used in building construction for things such as cables and heating pipes. Non-metallic minerals are those which do not produce new products upon melting. Clay for example is used in floor and wall tile as an...

...Chapter 6 Sustainability extra worksheet 4: Changing climate of Antarctica Science Understanding Verbal/Linguistic NAME: CLASS: DATE: In 2009 it was reported by the U.S. Geological Survey that the ice sheets in the southern part of the Antarctic Peninsula (Figure 1) were disappearing and that the change in the amount of ice was significant. Since 1998 approximately 4000 square kilometres of ice has been lost from one area. This area of ice lost is about one and a half times the size of the Australian Capital Territory (ACT). This loss of ice is regarded as very strong evidence of the effects of global warming on the planet. [pic] Figure 1 This map identifies the main areas of Antarctica. However, in the same year it was reported by the Australian Antarctic Division that the ice is expanding in eastern Antarctica (see Figure 1) and parts of eastern Antarctica are becoming cooler. Ice core drilling in the ice off Australia's Davis Station in East Antarctica revealed that in 2008 the ice had a maximum thickness of 1.89 metres. The ice had not been this deep for 10 years. Since the 1950s, when continuous record began, the average thickness of the ice at Davis has been 1.67 metres. Data collected do not provide any evidence of large scale melting of ice over most of Antarctica. The loss of ice in the west over the last 30 years has been more than offset by increases in the Ross Sea Region which is just one part of eastern Antarctica. ...

Sci/245 Comparison Worksheet

...Associate Level Material Comparison Worksheet Use the following table to compare extrusive and intrusive rocks. Describe and compare each type in at least 150 words. Extrusive Rock Intrusive Rock Extrusive rock refers to igneous volcanic rock formation in which hot magma from inside the Earth flows out to the surface as lava or explodes violently into the atmosphere to fall back as pyroclastic. This is different from intrusive rock formation, in which magma does not reach the surface. The main effect of extrusion is that the magma can cool much more quickly in the open air or under seawater, and there is less time for the growth of crystals. Often, some of the lava fails to crystallize at all, becoming an interstitial natural glass or obsidian. If the magma contains abundant volatile components which are released as free gas, then it may cool with large or small vesicles (bubble-shaped cavities) like those found in pumice or scoria. These rocks form many kilometers below the Earth’s surface, as molten rock called magma flows into cracks or underground chambers. There, the magma cools very slowly over thousands to millions of years. As it cools, elements combine to form common silicate minerals, the building blocks of igneous rocks; the mineral crystals can grow quite large if space allows. Rocks that form in this way are called intrusive igneous or plutonic rocks. The mineral crystals within them are large enough to see without a microscope. There are many different...

Photovoltaic White Paper

...Photovoltaic Power Systems Compiled by Tracy Dahl Overview Photovoltaic (PV) technology converts one form of energy (sunlight) into another form of energy (electricity) using no moving parts, consuming no conventional fossil fuels, creating no pollution, and lasting for decades with very little maintenance. The use of a widely available and reasonably reliable fuel source—the sun—with no associated storage or transportation difficulties and no emissions makes this technology eminently practicable for powering remote scientific research platforms. Indeed, numerous examples of successfully deployed systems are already available. The completely scaleable nature of the technology also lends itself well to varying power requirements–from the smallest autonomous research platforms to infrastructure-based systems. This technology can be limited, however, by annual fluctuations in solar insolation, especially at extreme latitudes. Based on semiconductor technology, solar cells operate on the principle that electricity will flow between two semiconductors when they are put into contact with each other and exposed to light (photons). This phenomenon, known as the photovoltaic effect, was first discovered by Edmund Becquerel in 1839. Actual development of PV technology began in the 1950s and gained greater impetus through the NASA space program during the 1960s. Research continues today at national laboratories and within private industry, focusing on increasing conversion efficiencies...
