Term | Definition |

Water cycle | The continuous movement of water from the ocean to the atmosphere to the land and back to the ocean. |
Water table | The upper surface of underground water, the upper boundary of the zone of saturation |
Aquifer | A body of rock sediment that stores groundwater and allows the flow of groundwater. |
Artesian spring | A spring whose water flows from a crack in the cap rock over the aquifer |
Evaporation | Takes place when water from the oceans and the earths surface changes into water vapor. Energy from the sun causes evaporation. Water gains energy during evaporation. |
Condensation | Takes place when water vapor cools and changes into water droplets that form clouds in the atmosphere. Water loses energy during condensation. |
Precipitation | Is rain, sleet, snow, or hail that falls from clouds onto earths land and oceans. |
Runoff | |
Groundwater | The water located within the rocks below the earths surface is called groundwater. |
Porosity | The percentage of the total volume of rock or sediment that consists of open surfaces |
Permability | The ability of a rock or sediment to let fluids pass, through its open spaces or pores |
Impermeable | A rock that stops the flow of water is called impermeable |
Well | A human-made hole that is deeper than the level of the water table is called a well |
Zone Of aeration | Rainwater passes through the upper zone called zone Of aeration |
Zone of Saturation | Farther down the water collects in an area called the zone of saturation |
Is precipitation that flows over land into streams and rivers. This later enters oceans. | |
Transpiration | |
Percolation | Is the downward movement of water through pores and other spaces in soil due to gravity. |
Water releases from leaves then going into the air |
