© Stephanie Elkowitz 7 Tectonic Plate Boundaries SNAPs Lab Science Skills Station Objective 1. Model the motion of tectonic plates at plate boundaries. 2. Compare and contrast convergent, divergent and transform plate boundaries. 3. Compare and contrast a convergent plate boundary between oceanic plates, continental plates and an oceanic and continental plate. Skills Utilized Overview Tectonic plates are large slabs of Earth’s lithosphere. They move or slide over the asthenosphere – the top part of the mantle. Earth’s core unevenly heats the asthenosphere. This uneven heating causes the tectonic plates to move. Tectonic plates can move towards each other, move away from each other or slide past each other. When plates move away from each other, new lithosphere is created. When plates move towards each other, lithosphere is destroyed. When plates slide past each other, they “grind,” which creates disturbances such as earthquakes. At this station, you will study tectonic plate motion. You will model how the motion of tectonic plates and how the composition of tectonic plates impact what occurs at a plate boundary. Make observations Infer and/or Predict Compare and contrast Model a concept Illustrate a concept Divergent Boundary Plates moving away from each other Convergent Boundary Plates moving towards each other Transform Boundary Plates sliding past each other
