Use what you read in Section 3 “The Water Cycle” on pages 32-35 to complete this
framework with the important points of the reading assignment.
(1.) Water is naturally ________________________ through the water cycle.
The water cycle is the continuous process by which water moves through the
____________________ and __________________________ parts of the
environment. The source of the energy that drives the water cycle is the ________.
(2.) The water cycle has no real _________________________ or
_______________. When a water molecule absorbs enough heat energy to change
state it _____________________________ and become
_______________________________ (2 words). Even though this water came
from the ocean, evaporation turns it into ____________________ water.
This is because salt is a solid and cannot evaporate so it remains in the ocean.
(3.) Large amounts of water evaporate from ______________________ and
_________________________(2 words). Small amounts evaporate from
_________________________, _________________________, and your
_____________________.
(4.) Plants draw in water from the soil through their ____________________.
Eventually this water is given off through the leaves as water vapor in a process called
______________________________.
(5.) Small amounts of water vapor are released by animals when they
______________________.
(6.) Warm air carries water molecules high into the air where it is much colder. This
causes the water molecule to ___________________. This is called condensation.
(7.) Eventually the drops of water in a cloud become too heavy and they fall back to
earth in the form of _____________________, _____________________,
_____________________, or ____________________. This is called
_______________________________.
What Happened to It?
List four things that might happen to a drop of water once it falls to the earth as
precipitation.
Part I
Using the six terms on the Hydrologic Cycle graphic organizer in your notebook,
draw an illustration of the cycle. You should have an illustration for each term. Use
arrows to show that it is a circular cycle.
Part II
You will create a pie graph that shows the percentage of earth’s water found in each
of the following locations:
a. oceans
b. icecaps & glaciers
c. groundwater
d. lakes
1. To calculate the number of degrees to be represented by each location you
must multiply the decimal in the percentage column by 360 (the number of
degrees in a circle). Your total degrees should equal 360.
2. Use the protractor you have been given to draw a 360° circle. Put a dot in
the center of your circle and draw a radius from the center to the left side of
the circle. You will start measuring here.
3. Your completed pie graph should have four parts. Label each part with the
location and the percentage, not the number of degrees.

Part III
You are to create a bar graph of the least amount of time water is stored in the
reservoir locations listed in the chart (not counting oceans – water stays there
forever). Your finished bar graph should have three (3) bars.
