As students become aware of plate movements, they begin to identify patterns that set the stage for deeper understanding of a very complex topic. The activity uses a simple “Where’s Waldo” approach to identify tectonic symbols on a laminated World Plate Tectonic map. Objectives.
World Map of Plate Boundaries. “Where’s Waldo”-style geography. Mapping world plates helps students connect topography, earthquakes, volcanoes, and plates. Introduction. The plate tectonics mapping activity allows students to easily begin to identify basic tectonic processes on a global scale.
We refer to plate boundaries as constructive or destructive. Boundaries at which continental and oceanic crust converge are called _________________. At these boundaries the denser oceanic crust, and accompanying material, subducts below the lighter continental crust and dewaters.
Student will be able to correctly identify the landforms created by plate boundaries by performing the edible plate tectonics lab. Students will be able to accurately explain that the movement of Earth’s crustal. plates causes both slow and rapid changes in Earth’s surface by reflecting on their lab activity.
Constructive boundaries, also known as divergent boundaries, occur where two plates move apart. They are called constructive because sea floor spreading extends the crust. Teacher Demonstration - Stretching the Crust. Tension thins the crust, and normal faulting produces a rift valley.
The boundaries between plates can be convergent (collisional), divergent (extensional), or side-to-side movement (strike-slip or transform movement) and typically feature mountain ranges.
The data maps used in Discovering Plate Boundaries are, a map of seafloor age, a map showing earthquake location and depth, a map showing locations of recent volcanic activity, and a map showing the Earth’s topography and bathymetry. This slide contains details about the map projection.
