Plate Tectonics Graphic Organizers Extension Ideas Mapping Activity Using the map that’s included, I ask students to plot the location of several well-known volcanoes and to explain the relevance of their location. (Mt. St. Helens, Mt. Fuji, Aconcagua, Mt. Shasta, Mt. Redoubt…) Volcanoes can be marked with a red triangle. I also ask them to plot 5 recent large earthquakes with a yellow star and to explain the details—plates involved, death toll etc. Play Dough Activity A favorite review activity for my students is to demonstrate their knowledge of plate boundaries and the features they form (trenches, ridges, fold mountains…) with a container of Play dough. I’ll give each student a container and then ask them to show me what type of plate boundary produces a trench or to show how a rift valley is formed, create a feature found when two continents collide etc. I then wander through the classroom and ask them to explain their work. A ton of fun and the hands-on nature of the activity really helps to cement the concepts. (I currently do this activity with Seniors—they talk about it for days.) Have fun!

What plate boundaries would you cross? What is the plate movement at each? Draw arrows and include labels for all of the features. (trenches, ridges, boundaries…) Using a map of the world’s plate boundaries, draw a cross-section as if you were to travel from the coast of South America to the coast of Africa. What plate boundary would you cross? Label the oldest rocks and the youngest rocks on your diagram and include all features found along the way. © 2011-Addie Williams Plate Boundary Review Name:___________________________________ Illustration by Jose F. Vigil. USGS. Using the diagram above, write a well-organized paragraph to explain how plate tectonics relates to the existence of volcanoes and the occurrence of earthquakes. © 2011-Addie Williams © 2011-Addie Williams Color code the plate boundaries with colored pencils. Convergent = Blue Divergent = Red Sliding = Green Plate Boundaries Plate Tectonics Explain the Theory of Continental Drift. The theory, proposed by Alfred Wegner, that the earth’s continents were once joined in a supercontinent called Pangea. The continents have moved slowly over time to their present day location. Describe the properties of the LITHOSPHERE. Hard rocky outer shell of the earth that includes the earth’s continents and its ocean basins. The crust of made of igneous, sedimentary and metamorphic rocks. The crust floats on the mantle. Describe the properties of the ASTHENOSPHERE The asthenosphere is a layer of rock in the mantle that acts like a plastic (like silly putty) where movement from convection currents occurs. Draw and explain how CONVECTION CURRENTS relate to PLATE MOVEMENT. The convection currents in the asthenosphere push and pull the earth’s plates. Where the currents sink, the plates are pulled downwards, where the current rise, the plates are pulled apart. Explain three pieces of evidence to support the THEORY OF CONTINENTAL DRIFT Mesosauras fossils found in S. America and Africa where it looks as if the continents once fit together like puzzle pieces. The puzzle like fit of the continents. Where are the YOUNGEST rocks on Earth found? Explain. At spreading centers (mid-ocean ridges) and near volcanoes. © 2011-Addie Williams Plant fossils in the Antarctic indicate that it must have been closer to the equator / in a different climate zone than it is now. Where are the OLDEST rocks on Earth found? Explain. On the continents far away from spreading centers. Types of Plate Boundaries—Draw and explain each. Collision Boundary (Continent / Continent) Where two plates collide one plate will sink under the other (older, heavier plate) and fold mountains will form. Feature Formed ___________________________ Fold Mountains Himalayans Example Diverging Boundary (Ocean / Ocean) Subduction Boundary Where an ocean plate collides with a continental plate the heavier ocean plate slides underneath. Feature Formed ___________________________ Trench / chain of volcanoes Example Marianas Trench Diverging Plate Boundary (Continent / Continent) Where two ocean plates spread apart magma rises to the ocean floor. Where two continental plates diverge / spread apart a rift valley will form. Feature Formed ___________________________ Mid Ocean Ridge Feature Formed ___________________________ Rift Valley Example Example Mid Atlantic Ridge East African Rift Valley Draw and explain what happens at a Sliding / Transform Plate Boundary Where two plates slide past each other like lanes of traffic on a road. Feature Formed Fault zone Example San Andreas Fault Why do you think SUBDUCTION boundaries have the deepest earthquakes? The sinking plate gets pulled deep inside the earth, as the plate makes its way down it creates deep earthquakes in the earth. © 2011—Addie Williams Types of Plate Boundaries: Draw and explain each.
