Water Vocabulary
6th grade SOL review
| Term | Definition |
|---|---|
| water vapor | water in the form of a gas |
| groundwater | water that fills the cracks and spaces in underground rock layers |
| water cycle | when water moves through bodies of water, land, and living things |
| evaporation | liquid molecules turn to a gas |
| transpiration | process by which water is given off through the leaves of plants as water vapor |
| precipitation | water that falls to the Earth |
| irrigation | process of supplying water to areas of dry land in order to make the land suitable for growing crops |
| photosynthesis | process where plants use Carbon Dioxide, water, and energy from the sun to make food |
| habitat | the place where an organism lives - this place provides all of the things that it needs to survive |
| tributary | smaller streams and rivers that feed into a main river or larger body of water - it contributes water to the larger body of water |
| watershed | the LAND AREA that supplies water to a river system-also known as a drainage basin |
| divide | place where one watershed (land area) is SEPARATED from another (often a mountain range) |
| levee | natural - ridge made up of sediment deposit along a river bank man made-constructed along the edge of water to make the bank taller and prevent flooding |
| reservoir | a lake that stores water for human use |
| eutrophication | the process by which nutrients build up in a lake over many years (this is bad because it will eventually cause the lake to dry up) |
| pores | different sized SPACES between the particles of soil and rock |
| permeable | this describes a material that allows water to easily pass through or permeate, usually close to the surface (ex.: sand or gravel) |
| impermeable | this describes a material that water CANNOT pass through easily - this is usually deeper under the surface (ex.: clay or granite) |
| saturated zone | the area of permeable rock or soil that is TOTALLY FILLED WITH WATER |
| water table | the top of the saturated zone - the water level |
| unsaturated zone | layer of rocks and soil ABOVE the water table that is NOT completely full of water |
| aquifer | any underground layer of rock that holds water |
| spring | occurs when the water table meets the ground surface - groundwater bubbles or flows out of cracks in the rock |
| recharge | NEW water that enters the aquifer from the surface - replenishes and refills the aquifer |
| Artesian well | a well in which water rises on its own because of the pressure within the aquifer - it does not require a pump |
| wetland | area of land covered by a shallow layer of water during some or all of the year - protect shores from waves, absorb pollutants, improve water quality, and contain a wide diversity of life |
