Hydrological Cycle

6. the continuous flow of water above, below and across the surface of the Earth
7. the process of water changing from a gas to a liquid as it cools in the upper troposphere layer of the atmosphere
9. water droplets collide and combine or as ice crystals grow, they become too heavy to stay airborne and fall to the earth as drizzle, rain, hail, sleet or snow
12. when the upper surface of the saturated zone is free to rise and fall; rises and falls depending on rainfall and percolation
15. permeable layer confined between relatively impermeable layers; usually under pressure; water table level less variable
16. the movement of water vapor as it is carried by air currents
17. the movement of water through soil down to the water table
18. any porous water-bearing geological formation

1. is the rate of water that a well can supply over a long period of time
2. is an area from which surface runoff is carried away by a single drainage system
3. rainfall that does not reach the ground as it collects on plants, treetops, or other structures
4. once the soil reaches it capacity to absorb water, the water will begin to run over the land and move towards the lowest point by the force of gravity
5. water changes from liquid to gas state as it is heated by the Sun; it rises up into the atmosphere; this occurs from oceans, lakes, streams and the surface of Earth
8. area of soil where air is still present; water moves towards water table
10. area of soil where no gas is present; all spaces filled with water
11. the movement of water beneath the earth’s surface
13. the movement of water through Earth’s surface into the soil
14. tiny holes in the leaves of plants, called stomata, release water vapor into the air
