Solution:
The question asks to match the labels 'A) outer boundary of the exclusive economic zone' and 'B) outer boundary of the continental shelf' with the corresponding numbers on the diagram. Based on typical maritime zone definitions:
- The exclusive economic zone (EEZ) typically extends up to 200 nautical miles from the baseline. In the diagram, the boundary marked with '200 miles' and corresponding to number 4 or 5 seems to represent this. Given the context and the visual representation, number 4 is the most likely candidate for the outer limit of the EEZ.
- The continental shelf is defined by geological and legal criteria. The inner boundary of the shelf is usually the territorial sea limit (12 nautical miles). The outer limit of the continental shelf can extend beyond 200 nautical miles, but in this diagram, the boundary marked with '200 m' depth and corresponding to number 2 appears to indicate the edge of the continental shelf in this particular geological context, or a transition zone. The '12 miles' indicates the territorial sea. Boundary 1 is likely the baseline or inner territorial limit. Boundary 3 is within the 200-mile zone, potentially representing a specific geological feature or a sub-zone.
- However, the question specifically asks for the 'outer boundary of the continental shelf'. Looking at the diagram, the geological layers extend significantly. The dashed line labeled '200 m' is a depth contour, often used to delineate the shelf break. This corresponds to boundary 2.
- The 'outer boundary of the exclusive economic zone' is generally understood to be 200 nautical miles from the baseline. Boundary 4 is indicated as extending up to 200 miles in width from the coast, making it the most plausible representation of the EEZ outer limit in this diagram.
Matching:
| Boundary Type | Corresponding Number | Reasoning |
|---|
| A) Outer boundary of the exclusive economic zone | 4 | The 200-mile distance is explicitly indicated, aligning with the definition of the EEZ. |
| Б) Outer boundary of the continental shelf | 2 | The '200 m' depth contour often signifies the shelf break, which is the outer limit of the continental shelf. |
Note: Boundary 1 is likely the baseline or 12-mile territorial limit. Boundary 3 is within the 200-mile zone and might represent a specific geological feature or a sub-zone. Boundary 5 is further offshore and could represent a different zone or limit, but 4 is directly linked to the 200-mile distance for the EEZ.
