| Term | Definition |
|---|---|
| Evaporation | when a liquid turns into to vapor (gas). Because of heating. |
| Condensation | When a vapor (gas) to turns into a liquid. Because of cooling. |
| Precipitation | Rain, snow that falls to the ground |
| Surface Water | Any body of water above ground: river, stream, lakes, ponds, oceans |
| Infiltration | When water soaks into the ground fills the air spaces between rocks and soil |
| Ground Water | Water held underground in the soil |
| Plant Uptake | When water and nutrients like nitrogen are transferred from the soil and goes into plants |
| Transpiration | When plants take up water from the soil and release it as water vapor through their leaves |
| Runoff/Storm Water | Precipitation that does not soak into the soil but instead moves on the surface toward surface water (stormwater in cities) |
| Sublimation | The transition of a substance directly from a solid to a gas, skipping the liquid phase, triggered by heat. |
| Deposition | Phase transition where gas transforms directly into solid without passing through a liquid state. |
| Freezing | A thermodynamic phase transition where a liquid turns into a solid as its temperature drops |
| Melting | The physical process where a substance changes state from a solid to a liquid |
| Adhesion | Sticking together of particles of different substances. This is how water sticks to other materials |
| Cohesion | Sticking together of particles of the same substance. This explains how water molecules stick to each other which allows for surface tension. |
| Surface Tension | A force present within the surface layer of a liquid that causes the layer to behave as an elastic sheet. |
| Capillary Action | The movement of a liquid through or along another material against an opposing force, such as gravity. |
| High Specific Heat Capcity | The amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat, it takes more energy to increase the temperature of water compared to other substances. |
| Turbidity | Measures water cloudiness due to suspended particles. |
| pH | Measures acidity or alkalinity of water. |
| Conductivity | Indicates the presence of dissolved ions. |
| Eutrophication | Excessive nutrient enrichment in water bodies. |
| Consumptive | The removal of water from an aquifer or body of surface water without returning it to its source. |
| Non-consumptive | Does not or only temporarily removes water from the source. |
| Salinity | The amount of salt present in water. |
