The Incredible Journey

1. Cycle the paths water takes through its various states- vapor, liquid and solid-as it moves throughout Earth's systems(oceans, atmosphere, ground water, streams, etc.) Also known as the hydrologic cycle.
6. Two or more homogeneous(identical) or heterogeneous (different) atoms held together by intermolecular bonds.
7. the process of breaking down nutrients(food) into components that can be easily used or stored by the body.
10. atmospheric water that has condensed onto cooler objects. This usually occurs at night, when the relative humidity rises and the air temperatures cool.
11. the transition of a substance from the solid phase directly to the vapor phase, without passing through an intermediate liquid phase; the apposite of deposition.
15. the conversion of a liquid(e.g. water)into a vapor (a gaseous state) usually through the application of heat energy; the opposite of condensation.
16. the process of laying down sediment or accumulating layers of material carried in suspension. (2) the transition of a substance from a vapor(gas) directly to the solid phase without passing through an intermediate liquid phase; the opposite of sublimation. Frost is an example.
17. the state of water in which molecules move freely among themselves but do not separate like those in a gaseous state.

2. the process by which water absorbed by plants(usually through the roots) is evaporated into the atmosphere from the plant surface(principally from the leaves).
3. the act or process by which an organism exchanges gases with its environment; in animals with lungs, the process of inhaling and exhaling or breathing. Cellular respiration involves the release of energy from food through chemical reactions.
4. the process by which a vapor becomes a liquid; the opposite of evaporation.
5. water falling, in a liquid or solid state, from the atmosphere to Earth.
8. the state of water in which individual molecules are highly energized and move about freely; also known as vapor.
9. energy that pertains to the movement molecules within a material or object. As heat is added to a material, the movement of molecules within the material increases.
12. the natural force of attraction exerted by Earth on objects or materials on its surface that tends to draw them down toward its center.
13. the state of water in which molecules have limited movement.
14. the fluid secreted in the form of sweat by the sweat glands and as water that diffuses through the skin by humans and some other animals that helps lower an elevated body temperature.
