Since this is your first question for Yahoo! answers I would like to make sure you have a good experience and be sure you get a good answer. I am an earth scientist, specifically a geologist. I specialize in sedimentology and sequence stratigraphy of carbonate rocks. What I love about carbonate rocks is that they were all 'born.' Carbonate rocks are made from living things like oysters, clams, coral, algae, and even microbes. Sedimentology is the study of how these rocks formed as they were laid down as sediments, and sequence stratigraphy is the study of how those rock deposits are related in space and time to cycles of the earth's orbit and changing sea levels.  Another special interest of mine is speleology, the study of caves, and I am most interested in paleocaves which are ancient caves that in most cases have collapsed and been buried. \n\nEarth science is one of the most inclusive of all fields of science. Some fields of earth science are geology, oceanography, atmospheric science, glaciology, hydrology, and soil science. In practice earth science uses chemistry, biology, physics, mathematics, geography, and often includes engineering as well. Many "earth" scientists also study other planets. One of my friends makes maps of Venus. There are interdisciplinary fields of earth science like biogeochemistry which studys the cylces of things like carbon, nitrogen, and other chemicals through the environment. \n\nAs a geoscientist I have had the good fortune to work in many interesting places, such as Chile, Ethiopia, Albania, Barbados, Puerto Rico, Alaska, Spain, Netherlands, Belgium, Canada, Mexico, and just about every state in the US. I visited the world's largest copper mines in Chile, and the worlds driest desert, the Atacama. I worked in the Awash basin in Ethiopia among the Afar tribes. I worked in caves in Barbados and in Puerto Rico. I spent several years working in the Grand Canyon, and have been on top of Mt. St. Helens, the well known volcano. I have also visited volcanoes in Hawaii. I can think of no other field of study that can lead to so many exotic places. I can also say with certainty that I have been places on this planet where no other man had been before me, deep inside of caves. I've also had the great pleasure of studying carbonate rocks in the ocean, by diving.  \n\nAn ineresting website that describes the varied things an earth scientist does:\nhttp://www.earthsci.org/education/careers/geolo/geolo.html\n\nAGI has a lot of interesting earth science images:\nhttp://www.earthscienceworld.org/imagebank/index.html\n\nHere is a USGS website where you can see a live image of a volcanic eruption (when they get snow cleaned off the webcam): http://www.avo.alaska.edu/activity/Augustine.php\n\nOne of the best link sites for earth sciences:\nhttp://www.lib.berkeley.edu/EART/EarthLinks.html

What is the Earth made of?\nhttp://www.leo.lehigh.edu/envirosci/geology/penngeo/whatis/whatis.html\n\nChemical Structure of the Earth\nhttp://www.earth.northwestern.edu/people/seth/202/lectures/Minerals/compintro.htm\n\nStructure and composition of the Earth\nhttp://www.amonline.net.au/geoscience/earth/structure.htm\n\nThe way we know what makes the earth, chemically speaking is to test for it.  Such as the composition of the atmosphere is put through a mass spectrometer (http://answers.yahoo.com/question/index?qid=20060905084043AAQ20dx) this tells scientist exactly what elements are in the test sample and in what percent!  We do the same for tests in the earth, of course there are abundant other tests to perform, both chemical and by hand, to tell us a more rounded story of the formation of the earth's history.

Well, it is fairly simple. One of your best resources is weather.com. Look at a globe and you can learn a lot as well.

Depends where you look. We don't have records long enough to look at the statistics of earthwuakes for the whole of the Earth.\n\nHowever, over time, some areas become more active and some less so.

If you’re asking about the research discipline of “planetary geology,” then its origins are rather recent.  Speculation existed about the nature of other planets’ surfaces—e.g., Lowell’s canals on Mars or the oft-envisioned swamps of Venus—but until we started sending spacecraft to explore the worlds and bring back data, such speculations didn’t amount to much of a science.\n\nMost would consider Eugene Shoemaker (1928–1997) the founder of planetary geology; he started the Astrogeology Research Program of the United States Geological Survey in 1961.  Shoemaker’s focus was on asteroids and meteorites, but with increasing quantities of data returned to Earth by missions to Mars, Venus, and other locales, the science grew to encompass many different worlds.\n\nPlanetary geologists study the origin, evolution, and structure of planets and their moons, as well as comets and asteroids.  (The more general term “planetary science” includes disciplines that include orbital dynamics, planetary atmospheres, and so forth.)  Of course, Earth provides a spectacular example of geological processes at work, but many of them (plate tectonics, for example) are unique to our home world.  Nonetheless, interesting analogies exist to the kind of events that may have taken place on other planets, moons, and such, so the challenge is to know what to learn from the well-known terrestrial science of geology and when to keep an open mind.\n\n(At least that’s my best shot.  My background is in astronomy, though, so details of this description might be a little off.)\n\nFor some interesting popular-level articles on the topic of planetary geology, take a look at links on the Geology News website:\nhttp://geology.rockbandit.net/category/planetary-geology/\n\n\nRyan Wyatt\nRose Center for Earth & Space\nNew York, New York

Igneous, they tell us a lot about what the age of the Earth and location of the poles.\n\nSedimentary, tell us the climate of an area and preserve fossils.\n\nMetamorphic, they look cool but are hard to tell anything from.  Their general location tells us of orogenies and faults.\n\nAll rocks are important and different geologists study different things.  Oil bearing shale is important to some geologist since if we can figure out an economical method of extraction we wouldn't be dependent on other countries for oil.\n\nGeology is like a big puzzle, and it's interesting seeing how the pieces fit together.

National Geografic website has a lot of information about it. \nIf you go to the linlk provided and then to the section of Natural Forces, you will find a lot of material to support your research. \n\nSecond link is about simulate and understand these events, explaning how it works at all their levels. You can find it to Earthquake, Hurricane, etc. I've putted the link to Vulcanoes\n\nGood luck

I would suggest the rock cycle. This is a basic earth science project that you can make as simple or complex as you want. You can identify the three major parts and how they interact going from one part of the cycle to another. You can identify the different properties of these rocks (and find samples if you want). If you want to make it really elaborate, you can bring in how plate tectonics drives the rock cycle, and how volcanism, metamorphism, and sedimentation form the Earth's surfaces.\n\nAnother topic that might be interesting to you would be to identify all the products and materials around you that come from rocks and minerals. Since this includes almost everything (e.g gypsum wallboard, clay in ceramics, iron in cars, aluminum in beverage containers and cars, plastic made from oil, shampoo made from oil, household detergent made from oil, electricity made from burning coal and natural gas, salt on your table, etc). You could look for the most surprising things, and could perhaps include how soil is made from weathered rock so even trees and plants come from rocks. You can do some research on how each of these materials is mined and where it comes from. You get the idea, right? \n\nDepending on where you live, you might do something on natural hazards in your area.If you have earthquakes you could find a fault map for your area and research earthquake hazards. If you have landslides or coastal erosion you could research what causes these things. Of course, if you live next to a volcano that is an excellent topic.  For example, see if you can find an eruption hazard map.  You might want to make sure your teacher approved of this because it might not be within the scope of your class (some teachers might consider this geography more than earth science). \n\nJust a bunch of ideas from a geologist. Hope this helps.
