Student Exploration: Ocean Mapping

Name: Date: Student Exploration: Ocean Mapping Please go to the first website provided to you on Canvas. Gizmo Warm-up To measure the depth of the ocean floor, scientists use a technology called sonar. A pulse of sound waves is emitted by a transmitter. The waves bounce off the ocean floor and return to the instrument. The time it takes the signal to return to the device is recorded and analyzed to determine the depth of the ocean at that point. The Ocean Mapping Gizmo™ allows you to create and interpret maps made by this method. 1. On the 3D POINT pane, the blue grid represents the ocean surface. The tan grid represents a depth of 6 meters (19.7 feet). Each cube has a height of 1 meter. To find the depth of the ocean, subtract the number of cubes from 6 meters. A. How many cubes are stacked below the boat? 5 B. How deep is the ocean at this point? 1 meter 2. Select the TABLE tab to check your answer. Were you correct? yes
