How many watersheds are in the continental United States?

• A. 200
• B. 2,110
• C. 2,200
• D. 3,000

Answer: (B)

The correct answer is based on the classification of hydrological areas, specifically the number of watersheds defined in the continental United States. Watersheds are essential for understanding water management, ecology, and environmental protection. The United States Geological Survey (USGS) provides detailed data on these areas, and it recognizes approximately 2,110 watersheds across the continental U.S. Each watershed is a land area that drains into a specific water body, such as a river, lake, or ocean, and their delineation is vital for effective water resource management and conservation efforts. This number reflects a well-established system for monitoring and managing water resources at local, state, and national levels.
