Mrs. Evans: Learning Guide Oceanography Unit 2 Bathymetry, Map Skills and Plate Tectonics Big Idea: The Earth has one big ocean with many features. Why do the ocean’s size, shape and features (mid-ocean ridge, rift valleys, abyssal plains, continental shelves and slopes, trenches) vary due to the movement of Earth’s lithospheric plates? What are the main ocean bottom features? How do oceanographers describe direction and location? (longitude, latitude, altitude and depth) Learning Targets Activities Using a topographical map of contour Map Skills intervals, explain what it means when the contour lines are close together, far Snack Tectonics apart, form a “loop” or form a “V” shape. Globe Scavenger Hunt 2.1 Interpret nautical charts, bathymetric Drown a Mountain maps and profiles. 2.2 My Own Private Island Explain the theory of plate tectonics and the formation and evolution of AMS Investigation 2 A & B ocean basin features through time. 2.3 Give an example of a place in the world where each of the following events is occurring. Be as specific as you can. Listing the name of a continent or country may not be enough.
