PRESENTATION OUTLINE
Water cycle- The continuous process by which water is circulated throughout the earth and the atmosphere through evaporation, condensation, precipitation, and the transpiration of plants and animals.
Precipitation- rain, snow, sleet, or hail that falls to the ground
Evaporation- The change of a liquid to a gas
Runoff- Water that flows over the ground surface rather than soaking into the ground
Infiltration- Flow of water from the land surface into the subsurface.
Transpiration-Plants release water vapor into the air
Condensation- The change from a gas to a liquid
Groundwater-The water that is beneath the Earths surface
Velocity-the speed of something in a given direction
ex: speed of a river
Gradient-steepness of a stream channel
Channel-A body of water joining two larger bodies of water.
Discharge-An outflow of water from a stream, pipe, groundwater aquifer, or watershed; the opposite of recharge.
Headwaters-Beginning of river
Tributary-a stream of river thst flows into a larger stream of river
Load (stream load)-The materials other than water carried by a stream
Deposition-Process in which sediment is laid down in new locations.
Delta-A fan shaped mass of rock material deposited at the mouth of streams
Levee- Form by deposition, keep water from spilling over
Floodplain-An area along the river that forms when sediment is deposited when the river overflows its banks.
Flood-A very heavy flow of water, which is greater than the normal flow of water and goes over the stream's normal channel.
Dam-A barrier constructed to hold back water and raise its level
Drainage basin- An extent or an area of land where surface water from rain, melting snow, or ice converges to a single point at a lower elevation
Watershed-An area of land that is drained by a river system
Water table-The upper surface of underground water; the upper boundary of the zone of saturation
Zone of Saturation-Lower levels of soil where all spaces are filled with water.
Zone of Aeration-The top zone, right below the surface where the pores are filled with water and air
Porosity-Percentage of open spaces between grains in a rock.
Permeability-Ability of rock or soil to allow water to flow through it
Spring-A flow of groundwater that emerges naturally at the ground surface
Hot Spring-a spring of naturally hot water, typically heated by subterranean volcanic activity
Geyser-A fountain of water and steam that builds up pressure underground and erupts at regular intervals.
Aquifer-An underground formation that contains groundwater
Cavern-A cave, especially one that is large and underground
Sinkhole-A depression produced in a region where soluble rock has been removed by groundwater
