Teaching The Hydrosphere

The Hydrosphere

All the water on Earth is part of the hydrosphere. Some water is salty and is called saltwater. Water that doesn't have much salt is called freshwater. Water can be a liquid, a solid (like ice), or a gas (like steam). A process called the water cycle makes the water on Earth change and move over and over again.
