Background Information
Water is always cycling between the land to the air and back again. This
process is known as the water cycle.
The water in the atmosphere comes from the Earth’s surface water. Surface
water evaporates (changes from a liquid to a gas) and becomes water vapor.
Water vapor is water in the atmosphere. Water vapor is invisible and is in the
form of a gas.

Most of the water in the atmosphere comes from the oceans, especially from
tropical oceans. Wind moves the water vapor to cooler areas where the water
vapor may condense (change from a gas to a liquid) and form precipitation.
Precipitation is any type of water that falls to Earth’s surface such as rain, snow
and sleet.
Precipitation is due to condensation. Condensation does not occur at one
particular temperature. It is due to a difference between two temperatures; the
air temperature and the dew point temperature. The dew point is the
temperature at which water vapor will start to condense out of the air as liquid
water.

When water evaporates, it takes in heat energy from the air causing the air
around it to cool down. This is one reason why the air is cooler by the beach in
the summer time. As water condenses, the water releases heat and warms up
the air around it. The release of heat energy during condensation is a factor in
the formation of hurricanes. The exchange of heat energy that occurs during
evaporation and condensation affects wind patterns and the weather.
*Sublimation is when water changes from a solid (such as ice
and snow) directly into a gas. This usually only happens at high
altitudes.
*Deposition is when water vapor changes directly from a gas to
a solid. This occasionally occurs in clouds when snowflakes are
formed or when frost collects on the grass on cold mornings.

“Most of the thermal energy at the Earth’s surface is stored in the Ocean. The
ocean and atmosphere work together to move heat and fresh water across the
globe. Wind-driven and ocean current circulations move warm water toward the
poles and colder water toward the equator. Thus, the absorption and movement
of energy on the Earth is related to the ocean and atmosphere working together
as a system.”
(http://oceanservice.noaa.gov/education/pd/oceans_weather_climate/energy_oceans_atmosphere.html, 2012)
Water vapor in the atmosphere does not only come from the oceans. It also
comes from other sources such as rivers, streams and transpiration.
Transpiration is when water is released to be evaporated from the leaves of
plants. This occurs when plants go through photosynthesis. Transpiration
accounts for 10% of the water vapor in the atmosphere.

High in the atmosphere, gaseous water (water vapor) cools down, condenses
and turns into clouds. When molecules of water in clouds collect into big enough
drops, they fall on us as rain, snow, sleet or hail depending on the temperature.
Rain, snow, sleet and hail are types of precipitation. Sometimes clouds form on
the ground and form fog. Fog forms when moist air suddenly drops in
temperature and condenses.

When water falls back to earth, some of the water infiltrates or sinks into the
ground and becomes ground water. Other water flows on the surface of the
Earth and is called runoff. Eventually, the runoff from the continents returns to
the oceans completing one turn of the water cycle. The same water has been
cycling on Earth for billions of years.
http://ga.water.usgs.gov/edu/watercycle.html
Fun Facts:
*The length of time an average water molecule stays in the atmosphere is 9
days.
*The length of time an average water molecule stays in the ocean is 3200
years.

There is a fixed amount of water on Earth that is constantly moving and
changing forms through the water cycle. All of this water is known as the
hydrosphere. Even though water is constantly moving through the hydrosphere,
the amount of water in the atmosphere and on the Earth’s surface is always the
same. 97% of the Earth’s water is in the oceans and only 3% of the Earth’s water
is fresh water. “Although the atmosphere may not be a great storehouse of water,
it is the superhighway used to move water around the globe.” (U.S Geological
Survey, 2012).
The water cycle is a continuous process that never ends. This is
important because water is the most important molecule on our planet. All life
on Earth is dependent on a clean supply of water.

Understanding the water cycle is an important part of understanding our
weather and weather patterns. The sun’s heat energy drives the water cycle by
causing evaporation. The cycling of water in and out of the atmosphere is the
main cause of weather patterns on Earth. Weather is the state of the
atmosphere at a given time and place. Weather includes the amount of water
vapor in the atmosphere, the amount and type of clouds, rain, snow, and other
types of precipitation.
Weather is studied and predicted by scientists called Meteorologists. The
science of meteorology is the study of the entire atmosphere, including the
weather. To understand and predict the weather, meteorologist must first
understand how the atmosphere heats and cools, how clouds form and produce
rain, and what makes the wind blow.

Science Reading for Success Passage One
The Water Cycle
By Sharon Fabian (Edhelper.com)
If you haven't heard this before, it might sound a little disgusting, but it's true. The
water that you drink today might be the same water that your little brother took a bath
in last year. It might be the same water that people on the other side of the world used
to wash their clothes or cook their vegetables one thousand years ago. It might even
be the same water that a tyrannosaurus rex drank to wash down a hearty meal millions
of years ago!
The water that we have on the earth today is the same water that the earth has
always had, and the same water that it always will have. The earth's water constantly
recycles itself in a process that is called the water cycle.
The water cycle has three main stages, evaporation, condensation, and precipitation, which
repeat over and over again endlessly. This process cycles water from the earth, through the air,
to the clouds, and back to earth again.
Evaporation is when heat, usually from the sun, changes liquid water on the earth to water
vapor which rises up into the air. When the sun dries up a puddle of water, this is evaporation.
You can also see evaporation in everyday events. When you put wet clothes into your clothes
dryer, and later take out dry clothes, evaporation has gotten rid of the water for you. When you
paint a picture, and let it sit to dry, evaporation dries the paint.
Condensation is the part of the process that changes water vapor back into liquid water or ice.
As warm air rises, it meets cooler air in the atmosphere, which changes it back to water or ice
and forms a cloud. This is condensation. The water drops that collect on the outside of a glass
of ice water or soda are also condensation. These water drops don't come from inside the
glass, they condense from the air around the glass.
Precipitation is rain, sleet, or snow. It is the part of the water cycle that brings our water back
down to earth. As a cloud fills up with water drops or ice crystals, it starts to get heavy. Sooner
or later gravity takes over, and pulls the water back to earth. It rains, or it snows.
After the rain falls to earth, it may stay here for a long time. Some water stays underground
among the rocks for thousands of years. Eventually, however, the water will end up someplace
where it can be evaporated, often in the ocean, and then the water cycle repeats itself.
Evaporation, condensation, precipitation, evaporation, condensation, . . .
So, if we have as much water as we ever did, why are people trying to conserve water? The
problem with water is not that we might run out of it; the problem with water is keeping
enough of it ready to use. The water cycle can take a long time. Much of the water that falls
32
back to earth ends up in the oceans, which of course are salt water, or in glaciers, which are
frozen. Only a small part of the earth's water is available for our use at any particular time. And
people are using more and more water all the time. So the challenge is to keep a supply of
clean, fresh water available for people to use. Drinking water that a dinosaur once drank might
seem a little strange, but having to drink polluted water -- now, that would be really disgusting.

Science Reading for Success Passage 2
Water Vapor and Weather
By Cindy Grigg (edhelper.com)
Water on Earth can be found in three forms or states. Water in a solid state is ice. We know
water best as a liquid. It can also be a gas called water vapor. Water vapor is water in the form
of an invisible gas. It is held in the air until it changes back to water. When the air gets cooler,
the water can condense in the air. It changes from a gas into a liquid. It first condenses as tiny
little droplets, which make clouds. When the droplets get bigger and heavier, they are pulled to
the ground by gravity. This is precipitation. Precipitation can be rain. It can be frozen
precipitation called sleet, snow, or hail. It can be drops of dew on the grass in the morning. It
can be frozen dew that we call frost.
When talking about weather, we often hear the word "humidity." Humidity is a measure of
how much or how little water vapor is in the air. In summer, the air may feel sticky. Then there
is a lot of humidity; there is a lot of water vapor in the air. Weather people often talk about
"relative humidity." Relative humidity is a percentage. It compares the amount of water vapor
in the air with the amount of water vapor the air could hold at a certain temperature. For
example, the weatherman might say that the relative humidity is thirty percent. He means that
the air holds thirty percent of the water vapor it could hold at the current temperature.
The current temperature is important in talking about water vapor. The temperature of the air
determines how much water vapor the air can hold. The warmer the air is, the more water
vapor it can hold. Weather people also talk about the "dew point." Dew point is the
temperature at which water vapor will start to condense out of the air as liquid water. If the
ground is cooler than the air, the liquid water may collect as dew. If the air temperature drops,
the liquid water may fall as rain. Knowing the temperature and the dew point can help you tell
whether or not it will rain. For example, suppose a weather person says that the temperature is
seventy degrees. She says that the dew point is sixty-six degrees. You know that if the relative
humidity is high and the temperature falls to sixty-six degrees, it will rain.
