What is one of the important roles of a watershed?

• A. Soil formation
• B. Water supply
• C. Climate regulation
• D. Fossil fuel storage

Answer: (B)

A watershed plays a crucial role in the water supply as it is a land area that channels rainfall and snowmelt to rivers, lakes, and reservoirs. This natural system collects and stores precipitation, which is essential for maintaining both surface and groundwater resources. Healthy watersheds contribute to the availability of clean water for drinking, irrigation, and other uses while also supporting aquatic ecosystems.

While soil formation, climate regulation, and fossil fuel storage are all important environmental processes, they do not specifically highlight the primary function of a watershed in the context of water supply. Watersheds are fundamental in the hydrological cycle, making them critical for sustaining water availability in various ecosystems and human activities.
