Earth is the only planet in the solar system with vast oceans of water.

70% of Earth’s surface is covered by water.

Where is most of Earth’s water found?

Where are some of the other places where water is found on Earth?

ComparisonComparison970 ml represents the amount of water in Earth’s oceans - salt water

30 ml represents total amount of fresh water on Earth

25 ml of that is frozen or underground

5 ml of fresh water (0.5%) is water available for use by land plants and animals, including humans

Fresh water is limited - Life depends of water

Living ResourcesLiving ResourcesTo maintain a high quality of life for all living things, water must be available

Think about & write ideas on:What prevents us from running out of water?

Where does new water come from?What can people do to ensure that there is plenty of water for people and other living things on Earth?
