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.
