Lesson Worksheet: The Distribution of Water Science
In this worksheet, we will practice describing and modeling the distribution of water on Earth and how much of this can be used by humans.
Fill in the blank: Most water on Earth is , so it is unusable.
- Asalt water
- Bfresh water
Which list contains only sources of fresh water?
|List 1||List 2||List 3|
- AList 1
- BList 2
- CList 3
Pick the pie chart that shows how much of Earth’s surface is covered by water.
How many quarters of Earth’s surface are covered by water?
- AThree quarters
- BTwo quarters
- COne quarter
- DFour quarters
Why is most fresh water on Earth unusable?
- AIt is dirty.
- BIt is frozen.
- CIt is polluted.
- DIt is underground.
This pie chart shows the distribution of water on Earth.
Which color represents salt water?
Which number points to frozen water?
Which number points to where salt water can be found?
The 4 L of water in this measuring cup represents the total amount of water on Earth.
How much of this 4 L of water would represent usable water?
We can use the 4 L of water in the bigger measuring cup to show the total amount of water on Earth.
What should we do to show how much of this water is fresh water?
- AWe should pour only 30 mL from the bigger measuring cup into the smaller measuring cup.
- BWe should pour 100 mL from the bigger measuring cup into the smaller measuring cup.
- CWe should add 100 mL to the bigger measuring cup.
