Wonderful Watersheds

5. a type of surface that does not allow water to pass through, often found in urban areas
6. low-lying areas that are regularly saturated with water, providing habitat for diverse species
8. a smaller river or stream that flows into a larger one
9. water stored beneath the Earth’s surface, filling the porous spaces in soil, sand, and rock
11. a man-made lake where water is stored for future use, often behind a dam
12. the process by which water soaks into the subsoil and rocks
15. to remove pollutants from water as it moves through a watershed, naturally or artificially
16. large expanse of trees, crucial for absorbing rainwater and supporting diverse life

1. water that has been used in homes, industries, and businesses and is not suitable for immediate reuse without treatment
2. vast, often flat areas that can be found at lower elevations
3. flowing body of water that may start as a small stream and grow as it heads towards the ocean
4. coastal area where freshwater from rivers mixes with saltwater from the sea
7. this acts like a natural barrier, separating one watershed from another
10. the area of land where all of the water that falls in it and drains off it goes into the same place
13. water from rain, snowmelt, or other sources that does not soak into the ground but flows over Earth’s surface
14. underground layer of rock or sediment that holds and transmits groundwater
