Question

identify and label the plate boundaries and/or features that are illustrated. match the label to the boundary or feature shown.
deep sea trench
rising magma and divergent boundary
subducting and melting
volcanoes on overridng plate
mid ocean ridges

Explanation:

To solve this plate boundary and feature matching problem, we analyze each label and feature:

Step 1: Analyze Each Feature/Label

• Mid - Ocean Ridges (A): Mid - ocean ridges form at divergent boundaries where tectonic plates move apart. In the diagram, the area with rising magma (E) and the spreading oceanic plates (A) corresponds to mid - ocean ridges, as new oceanic crust is created here.
• Rising Magma and Divergent Boundary (E): At divergent boundaries (like mid - ocean ridges), magma rises from the mantle to fill the gap between separating plates. So E matches with rising magma and divergent boundary.
• Deep Sea Trench (B): Deep - sea trenches form at convergent boundaries where one plate subducts beneath another. The “Plate Boundaries” label (B) near the subducting zone corresponds to a deep - sea trench.
• Subducting and Melting (C): At convergent boundaries, the subducting plate (oceanic plate) descends into the mantle, where it subducts and melts. The area labeled C (near the subducting plate) matches this process.
• Volcanoes on Overriding Plate (D): As the subducting plate melts, magma rises through the overriding plate, forming volcanoes. The area labeled D (on the overriding continental plate) corresponds to volcanoes on the overriding plate.

Matching:

• A: Mid Ocean Ridges (since it’s the divergent boundary with spreading plates)
• B: Deep Sea Trench (convergent boundary with subduction, forming a trench)
• C: Subducting and melting (the subducting plate descends and melts)
• D: Volcanoes on overriding plate (magma from subduction forms volcanoes on the upper plate)
• E: Rising Magma and Divergent Boundary (magma rises at the divergent boundary between oceanic plates)

Answer:

• A: Mid Ocean Ridges
• B: Deep Sea Trench
• C: Subducting and melting
• D: Volcanoes on overriding plate
• E: Rising Magma and Divergent Boundary
