Plate Tectonics Map Project DUE DATE TBA Your Goal: Create your own fictional world complete with continents, oceans, tectonic plates, mountains, earthquakes, volcanoes, and other evidence of a dynamic earth. Your world will have its own fictional history that explains the locations of these detailed features. You will create a Mercator Projection Map (rectangular map of a spherical planet like the one above) that illustrates all of the features of your world. Your map must be large (something like poster board size will do) and you will be graded highly on creativity and effort. Maps can be 2-dimensional or 3-dimensional. Step One: Begin brainstorming what your world is going to look like. Create a small "sketch" map as a rough draft. Decide what the major continents (at least 7) are and name them. You'll choose continental margins (shapes) that reflect on a long geologic past of plate movements, collisions, and changes. The location of the continents should also start to tell a story of the past. [Think about Pangea Gondwanaland + Laurasia modern continents.] In your sketches, include two prior dates in which your continents were in a very different location (again, think about Pangea, Gondwanaland, and Laurasia) so that we can see the history of your planet! Select dates for these maps of the past. Depending on where your continents are choose oceans and name them. Once you have these drawn out in a sketch add plate margins and name the tectonic plates that are created by where you place your boundaries. Remember that you can have oceanicoceanic, oceanic-continental, and continental-continental boundaries. In other words the "lines" of your plates can go anywhere on the map, through continents and/or oceans. You'll address what features you'd find across your world later on. Start to think about where divergent, convergent, and transform boundaries will be located. For example if you have two continents that "fit together," once were joined, and are now moving away from one another you'll place a divergent boundary between them. This is important especially for the large tectonic plates on your map. You may have to make changes to your world if you find inconsistencies. Use a pencil! Continue to add details to the rough draft sketch that you've now created. Your rough draft will be checked for part of your project grade. Checklist #1: ____ Continents (at least 7) ____ Continental margins/borders (shapes) - locations must tell a story - include sketches of two additional dates in the past where the continents were in different locations ____ Oceans ____ Tectonic Plates (at least 12) Step Two: Start marking divergent, convergent, and transform boundaries on your map. Reference Global Map of Plate Boundaries on the Wiki to help you. Remember that different sides of a single plate could be moving in several different directions. Look at the Pacific Plate for example. Your world is one giant puzzle and your plates are puzzle pieces, think about this when you consider where plates are moving. Ex. A plate moving in a relative northward direction is probably colliding with a plate to the north of it as well as pulling away (diverging) from a plate to the south of it. Using handout called, "Types of Plate Boundaries" and start deciding what types of features you are going to find along your plate boundaries. For example, if you have a divergent boundary between two oceanic plates (look up Divergent: Oceanic-Oceanic on your worksheet) you'll find that you should place a Mid-Ocean Ridge along this boundary. Make notes on your map where you'd find: Mid-Ocean Ridges, Earthquake/Fault Zones, Volcanoes, Rift Valleys, Deep Ocean Trenches, Volcanic Mts. (land), Island Arcs, Undersea Volcanoes, Mountains, Rift Zones, etc. Note that your maps may change slightly depending on your results. Ex. If you find an Oceanic-Oceanic Convergent boundary you might add an Island Arc (like Japan) to your world near that boundary. You may also add "Ancient" mountains that exist on your continents from earlier continental movements. These mountains may be used as evidence to piece the continents together. (Note: they should have a different symbol in your key than modern folded mountains caused by plate collisions) Check List #2: Plate Boundaries are labeled: ____ Divergent Boundaries ____ Convergent Boundaries ____ Transform Boundaries Features at plate boundaries (or ancient features, possibly in the center of plates) (must include at least eight different features) ____ Mid-Ocean Ridges ____ Earthquake/Fault Zones ____ Volcanoes ____ Rift Valleys ____ Deep Ocean Trenches ____ Volcanic Mts. (land) ____ Island Arcs ____ Undersea Volcanoes ____ Mountains ____ Rift Zones Types of Plate Boundaries and the Results of Each Type Continental:Oceanic Convergent Results: Subduction zone, basaltic oceanic crust is more dense than granitic continental crust. Deep Ocean Trenches, Stratovolcanoes and Volcanic Mts. on Land. ex. Cascade Mountains in the Pacific Northwest US and the Andes Mountains in South America. Compression, Reverse faulting, strong earthquakes. Oceanic:Oceanic Convergent Results: Subduction zone. Deep Ocean Trenches, Island Arcs, Undersea Volcanism. ex. Mariana Trench, Japan, Aleutian Islands (Alaska), Phillipines, Sumatra (2004 Tsunami). Compression, Reverse faulting, strong earthquakes. Continental:Continental Convergent Results: Folded Mountains on Land. ex. Himalayan Mts., the Alps in Europe, the Appalachian Mts. (ancient orogonies or mountain building events) in the Eastern United States. Compression, Reverse faulting, Strong earthquakes. Oceanic:Oceanic Divergent Results: Mid-Ocean ridges surrounded by new oceanic crust, the newest crust is closest to the rift zone. Tension, Normal faulting, weak earthquakes. ex. MidAtlantic Ridge, East Pacific Rise. Continental:Continental Divergent Results: Young plate boundaries, rift valleys that may eventually fill with ocean water creating a new ocean and then it becomes an oceanic-oceanic divergent boundary/mid-ocean ridge. Tension. Normal faulting, weak earthquakes. ex. Great Rift Valley Africa, Lake Superior in North America (ancient/dormant rift). Transform Boundaries Results: Moderate Earthquakes on land or on the ocean floor, shearing force. ex. San Andreas fault (California, USA), North Anatolian fault (Turkey, active), Chaman fault (Pakistan, active), Dead Sea fault (Middle East).
