UNIT 2: OCEANS AND RIVERS
THE PROBLEM OF THE WATER
DRINKING WATER
WHERE DOES MY DRINKING WATER COME FROM?
The water you get from your faucet can come from two
places - from the water in lakes or rivers (surface
water), or from water that comes from wells
(groundwater).
Many people in this area who live in large cities or
towns get their water for drinking from lakes and
rivers. But, most people in the Spain get their
drinking water from groundwater.
WHY IS DRINKING WATER IMPORTANT?
All plants and animals, including people, have to
drink water. If they don't drink enough good, clean
water, they will get sick, or can even die. But our
water isn't always clean enough. Sometimes it has
germs and chemicals in it. So, we have to clean the
water up before we drink it so that it doesn't make us
sick.
1
FIND OUT ABOUT THE WATER CYCLE
Watered Down = Precipitation
Precipitation is made up of any type
of water that falls to the earth like
snow, hail, mist, or rain.
Soaking it Up = Infiltration
Infiltration happens when water soaks
into the soil from the ground level.
It moves underground and moves between
the soil and rocks. Some of the water
will be soaked up by roots to help
plants grow.
Some of the water keeps moving down
into the soil to a level that is
filled with water, called ground water
2
Underground Water = Ground Water
Ground water is simply water
under the ground where the soil
is completely filled or saturated
with water.
Ground water that meets the
land surface also helps keep
rivers, streams, lakes and
wetlands filled with water.
Fill ‘er Up = The Water Table
The Water Table is found underground
where the rock and soil begin to be
filled or "saturated" with water.
When ground water meets the land
surface, it flows out and helps keep
rivers, streams, lakes and wetlands
filled with water.
Up, Up in the Air = Evaporation
Warmth from the sun causes water from
lakes, streams, ice, and soils to turn
into water vapor in the air.
Almost all of the precipitated water
(80 percent) goes right back into the air
because of evaporation. The rest runs
off the land or soaks into the ground to
become ground water.
Plant Sweat = Transpiration
Transpiration happens when plants give
off water vapor through tiny pores in
their leaves. This is the plant’s way of
getting rid of waste, just like people
and animals sweat when they’re hot!
This water vapor evaporates into the
air and is stored in the atmosphere
until it becomes clouds or precipitation
3
Humidity = Water Vapor
Water vapor is
water in a gas
form that is held
in the air until it
changes back to
water. The water
can change into fine droplets by "condensing" in the
air, and we get clouds. When the droplets get big
enough, they are pulled to the earth by gravity as
precipitation, better known as rain, snow, frost, etc.
Did You Know....?
*
97% of the water on earth is in the oceans
* Only 3% of the water on earth is freshwater
* About 2.4% of the water on earth is permanently
frozen in glaciers and at the polar ice caps
* About 1/2 of 1 % of the water on earth is
groundwater
* Only about 1/100 of 1% of the water on earth is
in the rivers and lakes
* Over 17,000,000 houses use private wells for
their drinking water supply
* A person can live about a month without food,
but can live only about 1 week without water
4
What Can You Do to Help?
There are many small things you can do
to protect your drinking water in a big way!
• If your parents change the oil in the car
themselves, make sure that they take the old
used oil to a recycling center. That keeps the
oil from getting on the ground and polluting the
water under the ground that someone may drink
some day

OCEANS AND RIVERS OF THE LAND
The planet is approximately 71% water and contains
five oceans, including the Arctic, Atlantic, Indian,
Pacific and Southern.
Their borders are indicated on the world image (right)
in varied shades of blue.
For many years only four oceans were officially
recognized, and then in the spring of 2000, the
International Hydrographic Organization established
the Southern Ocean, and determined its limits.
Those limits include all water below 60 degrees south,
and some of it, like the Arctic Ocean, is frozen.
Oceans by size:
13
1 Pacific (155,557,000 sq km)
2 Atlantic (76,762,000 sq km)
14
3 Indian (68,556,000 sq km)
4 Southern (20,327,000 sq km)
15
5 Arctic (14,056,000 sq km)

8. The Congo in Africa with a length of 2,900 miles
9. Parana in South America with a length of 2,800
miles
10. Amur-Ergun in Asia with an length of 2,761 miles
Rivers and seas of Europa and of
the Iberian peninsula.
18
Europe
Hundreds of rivers and their tributaries cross the
European continent.
The European out-standing rivers are:
19
Spain:
The main rivers of Spain flow west and south to the
Atlantic Ocean. The Duero (Douro), Miño, Tajo (Tagus), and
Guadiana rivers rise in Spain and flow through Portugal to
the Atlantic. The Guadalquivir River is the deepest and
most navigable. The Ebro River which flows through Zaragoza
flows into the Mediterranean Sea and is navigable for part
of its course. The rivers are a good source of electric
power
