4. the elevation at which it enters another stream or body of water

9. The ability of a material to let water pass through it
12. holes dug or drilled into the ground to reach an aquifer
13. Water flowing downslope along Earth’s surface
14. The difference between the original water-table level and the water level in the pumped well
17. the process by which precipitation that has fallen on land trickles into the ground and becomes groundwater
18. springs that discharge water that is much warmer than the average annual temperature
19. the method of transport for all particles small enough to be held up by the turbulence of a stream’s moving water

2. an elevated land area that separates one watershed from another
3. The upper boundary of the zone of saturation
5. bodies of water surrounded by land
6. above the water table, materials are moist, but because they are not saturated with water, air occupies much of the pores

20. a stream actively resumes the process of downcutting toward its base level
21. sand, pebbles, and cobbles that the stream’s water can roll or push along the bed of the stream
