It is constantly recycled in our world. The same amount of water that was here millions of years ago is still here today.

4. Water Cycle
Water is recycled over and over again through the water cycle.
Processes like precipitation, evaporation and condensation move water through different phases.

6. Water Scarcity Turn in any water cycle papers to the box.

7. How Much Water?
Though there is a fixed amount of water on earth, not everyone has equal access to it.

8. Water Every organism needs clean drinking water.
What happens when we don’t have clean drinking water?
Water scarcity happens when there is a lack of water, either because there is none or people cannot afford it.
