1. Bathymetric Map Project

2. Begin to find plate boundaries Ocean ridges, rises, and deep ocean trenches are all geologic features that are formed at plate boundaries Let’s use these features to draw some of our plate boundaries Use a Yellow colored pencil to trace over the ridges and rises (white areas).

3. Continue finding plate boundaries Use a Pink/Red colored pencil to trace over the trenches (blue areas). Use a Green colored pencil to trace over the Mountains (white on land).

4. Using earthquake and volcanic activity to find plate boundaries Earthquakes and volcanoes are common along tectonic plate boundaries Plot the 10 circled earthquakes with this colored symbol (blue oval) using latitude and longitude Plot the 8 circled volcanoes with this colored symbol (purple triangle) using latitude and longitude Complete boundaries by connecting the earthquakes and volcanoes using an Orange pencil

5. Label 7 major tectonic plates: Eurasian, Indo-Australian, Pacific, American, African, Antarctic, Nazca

6. What is the direction of motion for the major plates? Held stationary

7. Color the plates Lightly color each plate a different color. Remember that the left and right edges of the map are connected; color any split plates with the same color! Hold the map edges together, forming a cylinder, so that you can see this relationship. Make sure you have an arrow on each plate (except the African plate) to show direction of motion

8. Label Plate Boundaries Based on the movement of the plates and what occurs at the boundaries, label each major boundary. Divergent Convergent Transform
