Water Cycle

3. water that falls to the surface from the atmosphere as rain, snow, hail, or sleet.
6. table the surface between the saturated zone and the unsaturated zone (zone of aeration).
8. the constant circulation of water from the sea, through the atmosphere, to the land, and its eventual return to the atmosphere by way of transpiration and evaporation from the land and evaporation from the sea.
11. a system in which material moves from place to place but is not gained or lost from the system.
13. the part of the subsurface water that is in the zone of saturation, including underground streams.
14. water, in the form of liquid, vapor, and/or ice, that resides in Earth’s soil layer.
15. a place in the Earth system that holds water.

1. a weak chemical bond between a hydrogen atom in one polar molecule and an electronegative atom in a second polar molecule.
2. the change of state of matter from a liquid to a gas. Heat is absorbed.
3. a measure of how easy it is to force water to flow through a porous material.
4. a measure of the percentage of pores (open spaces) in a material.
5. the quantity of heat energy required to increase the temperature of a material or system.
7. the process by which water absorbed by plants, usually through the roots, is emitted into the atmosphere from the plant surface in the form of water vapor.
9. zone the zone, beneath the water table where all of the pores are filled with water.
10. the rate of movement of water from one reservoir to another.
12. the movement of surface water into rock or soil through cracks and pore spaces. percolate: the passing of water through a porous material.
