Procedure C Completion: Understanding Seafloor Polarity and Spreading

What is the task in Procedure C?

What do we need to consider when completing the diagram representing normal and reversed magnetic polarity on both sides of a mid-ocean ridge center in Procedure C?

Task in Procedure C

In Procedure C, the task is to complete a diagram representing the pattern of normal and reversed magnetic polarity on both sides of a mid-ocean ridge center. This involves shading the pattern of normal polarity on the west side of the ridge, indicating the direction of sea floor spreading with arrows, and labeling the locations of the youngest and oldest bedrock, as well as the hottest crustal temperatures.

Completing Procedure C requires a solid understanding of seafloor spreading and magnetic polarity distribution. The diagram must accurately reflect the symmetrical pattern of normal and reversed magnetic polarity on both sides of the mid-ocean ridge center.

Normal polarity indicates alignment with the Earth's current magnetic field, while reversed polarity indicates a reversed alignment. The completion of the diagram involves shading the normal polarity sections on the west side of the ridge to mirror the pattern on the east side.

The arrows drawn on both sides of the mid-ocean ridge should indicate the direction of sea floor spreading, typically moving away from the ridge center. The youngest bedrock, representing the most recently formed crust, is usually located closest to the ridge center, while the oldest bedrock is found farther away. The hottest crustal temperatures are closer to the ridge center due to increased volcanic activity.

For accurate completion of Procedure C, it is essential to follow the correct placement of normal polarity sections, draw arrows indicating sea floor spreading, and label locations of the youngest and oldest bedrock, and hottest crustal temperatures.
