    Gizmos Name: □ ale: Student Exploration: Plate Tectonics Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: asthenosphere collision zone, convergent boundary, crust divergent boundary earthquake, lithosphere, mantle, plate plate tectonics, subduction zone, transform boundary, volcano Prior Knowledge Questions (Do these BEFORE using the Gizmo.) t . Volcanoes are openings in Earth's crust where lava. gas. and ash can erupt. Where are active volcanoes located? Volcanos are active on locations where earthquakes occur often 2. An earthquake is a violent shaking of Earth s surface. Where are earthquakes common? Earthquakes are common between plates of land, so somewhere in Japan and California Gizmo Warm-up Volcanoes, earthquakes, mountains, and other features of Earth's surface owe their origin to the movements of plates: enormous, slowly- moving sections of Earth s crust. Al plate boundaries, plates collide, move apart move under or over each other, or slide past one another. The theory of plate tectonic s describes how the plates move, interact, and change the physical landscape. The Pi'ate Tectonics Gizmo shows a cross-section, or side view, of Earth. (Not to scale ) Above the cross section is a bird's-eye view of the same location. 1. Turnon Show labels. What are the layers of Earth that you can see? Crust -> Lithosphere -> Asthenosphere The lithosphere is a layer of rigid rock that consists of the crust and the upper part of Earth s mantle. The asthenosphere is a layer of the mantle that can deform like plastic. 2. Turn on Boundary name, and click on each boundary. What four boundaries do you see? Transform Boundaries. Convergent Boundaries Collision. Convergent Boundaries:Subduction Divergent Boundaries Reproduction far educaUsnal use cnty. Public sharing cr posting prohibited.

    Activity A: Sliding plates Get the Gizmo ready : • Select BOUNDARY A. Question: What happens when plates slide past one another? 1. Observe Boundary A is a transform boundary The arrows below the BOUNDARY A label will move the plales. Click the left arrow once to see how (he plates move. How would you describe the motion of plales in a Iransform boundary? The rnolion of the plate is moving away from me 2. Sketch. Draw a bird’s-eye view of (he plate boundary before and after the plate motion. Draw an arrow to show which way the plate moved. Before movement After movement 3. Locate: Turn on Show location. Where on Earth can you find iransform boundaries? (Note: You can refer I o a world map or atlas for location names.) II is located in California above south america and parts of India Highlight these locations on lhe map below. To do this, click on lhe drawing and select Edit.
