| Capillarity | The process by which water is drawn into openings due to the attractive force between water molecules and the surrounding earth materials |
| Climate | The overall view of a region's weather conditions over long periods of time |
| Ground Water | The subsurface water found beneath the water table in the zone of saturation |
| Hydrologic Cycle | A model, often a diagram, used to illustrate the movement and changes of state of water at and near Earth's surface |
| Infiltrate | Sink into, under the influence of gravity, the upper parts of earth's lithosphere where the water becomes subsurface water |
| Permeability | The degree to which a porous material will allow fluids, such as water and oil, to pass through it |
| Porosity | Percentage of open space in a material compared to its total volume |
| Prevailing Winds | Winds that blow from a certain compass direction for a large part of a year |
| Runoff | All the natural liquid water flowing at earth's solid surface, including stream flow |
| Seep | Sink into, under the influence of gravity, the upper parts of earth's lithosphere where the water becomes subsurface water |
| Sorted | A condition in which all the particles in a material are the same or similar in size |
| Stream Discharge | The amount of water that passes a certain spot in a stream in a specific amount of time, such as liters per minute |
| Unsorted | A condition in which all the particles in a material are of mixed sizes(or shape,or density) |
| Urbanization | The growth of a city environment |
| Water Cycle | A model, often a diagram, used to illustrate the movement and changes of state of water at and near earth's surface |
| Water Retention | Storing and retaining of percipitation on earth's land surfaces as ice or snow, or as liquid water on trees and other plants |
| Water Table | The interace between the zone of saturation and the zone of aeration |
