Which statement is true about Marine Shorelines Symbols vs Mines and Caves symbols?

• A. Quarry is a Marine Shorelines symbol.
• B. Quarry belongs to Mines and Caves symbols.
• C. Gravel pit is a Marine Shorelines symbol.
• D. Mill tailings are a Marine Shorelines symbol.

Answer: (B)

Symbol categories on maps distinguish coastal shoreline features from mining and cave features. Marine Shorelines symbols show things you’d find along the coast—sand, dunes, tidal flats, rocks shaped by the sea, piers, and similar shore-adjacent features. Mines and Caves symbols cover excavation sites and cavities, including quarries, mines, gravel pits, and tailings—features tied to mining activity rather than the coastal environment. A quarry is an open-pit excavation used to extract stone, so it belongs with the Mines and Caves symbols rather than Marine Shorelines. A gravel pit is essentially another mining excavation, so it would fit in the same mining-cavities category. Mill tailings are the waste material left after ore processing, also a mining-related feature, so they belong in Mines and Caves as well. Therefore, the statement that quarry belongs to Mines and Caves symbols is the correct one.
