Water cycle

This online resource investigates the Earth's spheres, with emphasis on water.

The site gives students an understanding of the Earth’s four environmental spheres (ie., the biosphere, hydrosphere, geosphere and atmosphere) and how they are connected.

This activity is the introductory experience to a series of lessons about water resources on Earth. Students can investigate the previously mentioned Earth systems by making observations in nature and identifying the systems in the natural world.

This interactive diagram looks at the Earth's water cycle.

The resource includes an interactive diagram that shows how the Earth's water is not only always changing forms between liquid, solid and gas, but also moving on, above and within the Earth.

The interactive diagram contains interactive features that when hovered over, display information and links regarding each stage of the cycle.
