Students learn how ocean depth is measured and discover the mid-ocean ridge as they chart the Atlantic seafloor.
In this activity, students will:
- READ background information about how scientists use sonar to measure the depth of the ocean.
- GRAPH longitude and ocean depth data on a provided graph. The graph creates a “side profile” of the Atlantic ocean floor. This reveals the mid-ocean ridge!
- ADD LABELS to the graph by coloring the Earth and the ocean and labeling the mid-Atlantic ridge and other features.
- ANSWER questions that review seafloor spreading and continental drift.
Teacher Notes:
