Study question
How does a long, narrow barrier island sit between the open Atlantic and protected mainland waters, and which map evidence helps you recognize that arrangement?
Map task
- Zoom until Assateague Island and the mainland are both visible.
- Use the lower-left scale to estimate the island's north–south length.
- Identify the ocean side and the bay side. Note where roads and developed areas stop.
Show a model answer
The island is a narrow strip running roughly north–south, with the Atlantic to the east and Chincoteague and Sinepuxent Bays toward the mainland. The measurement changes with endpoints and screen scale, so it should be reported as an estimate.
What this map supports
It supports orientation, place names, access patterns, and approximate distance. It does not show historical shoreline position, sediment movement, elevation, storm overwash, or water depth. Those questions need dated imagery or specialist datasets.
