Water
Gotta have it!

The water cycle is the continuous movement of water between land
atmosphere and oceans.
Evaporation is the process by which water
changes from a liquid to a gas or vapor.
Transpiration is the process by which moisture is carried through plants from
roots to small pores on the underside of leaves, where it changes to vapor and
is released to the atmosphere.
Earth’s water is balanced because the amount of precipitation is
equal to amount of evapotranspiration and runoff.
Desalination/distillation is one of mankind's earliest forms of water
treatment, and it is still a popular treatment solution throughout the world
today. In ancient times, many civilizations used this process on their ships to
convert sea water into drinking water.
Water Conservation
Water Protection
If an aquifer has high porosity, it will have high
permeability
The deepest zone of an aquifer is the zone of
saturation.
Water passes quickly through rock that is highly permeable. As the water
table’s gradient increases, the velocity of the water that runs through the
aquifer increases.
If the rock is not permeable enough,
Sometimes an ordinary well will run dry and
not have groundwater flow freely into it.
Because the water is under pressure water will
quickly flow through an artesian well.
Hot groundwater (heated by magma) that rises
to the surface is a hot spring.
Geyser- hot springs that erupts from small
vents
An aquifer is a formation, group of formations, or part of a
formation that contains sufficient saturated, permeable material to
yield significant quantities of water to wells and springs.
Pesticides contaminate because they seep into
groundwater and get into ground water---50%
of nation drinks from groundwater.
Sewage and fertilizers are two ways that
nitrogen is introduced into our water supply.
Sometimes my drinking water looks cloudy.
The cloudiness might be caused by the water in the pipes being under a bit
more pressure than the water in the glass, but is more likely due to tiny air
bubbles in the water.
The USGS Water website says that these are naturally in the water
in small amounts.
-salt, arsenic, sulfur, or radon and iron can naturally be found in
water.
The USGS uses many pieces of equipment, both mechanical and
electronic in order to measure water quality.
