Chapter 1. Pie Graphs
Part A: Background
Water is an essential to all life. The majority of water extracted for human use is for agriculture, followed by industry. Domestic or household use only accounts for about 8% of all water use, but it is one that we can directly influence with our daily actions.
As humans, we rely on fresh water (water that has few dissolved ions such as salt in it).
Part B: Examine the Data Set
The distribution of water on Earth can be divided by type (saltwater, freshwater), and source.
| Type of Water | Percent of Total Water on Earth |
|---|---|
| Oceans | 97% |
| Freshwater | 3% |
| Water Source | Percent of Fresh Water |
|---|---|
| Glaciers and Ice Caps | 87% |
| Groundwater | 12% |
| Surface and Other Waters | 1% |
| Water Source | Percentage of Surface and Other Waters |
|---|---|
| Lakes | 52% |
| Soil Moisture | 38% |
| Atmosphere | 8% |
| Rivers | 1% |
| Water in Living Organisms | 1% |

Instructions: Create a graph title, such as “Distribution of Water on Earth”. Take a blank circle and input the percentages, which would then be drawn in, colored, and labeled. Create three pie charts, one for each table in this order: Total water, followed by freshwater, followed by surface and other waters.
| Type of Water | Percent of Total Water on Earth |
|---|---|
| Oceans | 97% |
| Freshwater | 3% |
| Water Source | Percent of Fresh Water |
|---|---|
| Glaciers and Ice Caps | 87% |
| Groundwater | 12% |
| Surface and Other Waters | 1% |
| Water Source | Percentage of Surface and Other Waters |

| Rivers | 1% |
| Water in Living Organisms | 1% |
Part D: Apply Skills
Infographic 15.4 shows the breakdown of the three major sectors that use water, and how much.
Infographic 15.7 breaks the domestic portion further into how water is used in a typical U.S. household.
