Water is fundamental to life. All organisms need water to be able to survive. Water is considered the universal solvent because essential nutrients for life can dissolve within it. Water is therefore an important delivery mechanism that transports vital nutrients from one place to another within a cell keeping us and other organisms alive.

The unique thing about water is that all three states (liquid, solid and gas) exist naturally in nature. This ability allows the water cycle to replenish water around the world, particularly maintaining fresh water which we need to survive.

1. Evaporation and transpiration
2. Condensation
3. Water storage in the atmosphere
4. Precipitation
5. Runoff
6. Infiltration
7. Groundwater discharge
8. Water storage in oceans
