Human body is about 60% water.
Water is found in Earth’s spheres or subsystems. These spheres are hydrosphere, atmosphere, lithosphere, and biosphere.
The Water Cycle: Constant movement of water between Earth and the air as it changes state of matter.
Always repeating and does not have a start or end.
Evaporation and Condensation:
Energy for the water cycle comes from the sun.
This energy causes water to evaporate, which changes liquid water to water vapor.
Water vapor rises in the atmosphere and begins to cool, causing it to condense (change into water droplets).
Water droplets form clouds.
