Water Cycle

2. The unsaturated underground layer through which water moves downward.
4. The process in which tiny water droplets form around airborne particles such as dust, salt, or smoke.
8. These form when millions of tiny water droplets gather around particles in the atmosphere.
9. The process in which liquid water changes into water vapor.
10. The pulling force created by evaporation at the top of a plant that draws water upward from its roots.
11. Microscopic pores in plant leaves that allow water vapor to escape.
12. The process that occurs throughout an entire liquid when vapor pressure equals atmospheric pressure.
13. Water that falls from clouds as rain, snow, sleet, or hail.
15. The process in which water vapor cools and changes into liquid droplets.
18. An underground layer of saturated earth that stores water and supplies wells.
20. Roads, sidewalks, and roofs that prevent water from soaking into the ground.
21. The invisible gas that forms when liquid water evaporates.
22. These grow in colder clouds by absorbing surrounding water vapor.
24. Precipitation that flows across Earth's surface instead of soaking into the ground.
25. The main source of heat that causes water to evaporate.

1. Water that is stored and moves beneath Earth's surface.
3. The property that causes water molecules to stick to other surfaces.
5. The process in which plants release water vapor into the atmosphere.
6. The process in which precipitation soaks into the ground.
7. The specialized vascular tissue that transports water upward through a plant.
14. The deeper movement of water through underground layers toward the water table.
16. The process through which plant roots absorb water from the soil.
17. The property that causes water molecules to stick to one another.
19. The energy a fast-moving water molecule needs enough of to escape into the air.
23. The force that pulls precipitation toward Earth and causes runoff to flow downhill.
