Three phases of water in the environment: The water cycle | Introduction to Earth systems | meriSTEM

Professor Andy Hogg from the Australian National University (anu.edu.au) describes the three phases of water in the environment. This as part of a series of educational videos on our Earth's water.

This clip has been created by the Research School of Earth Sciences (rses.anu.edu.au). These resources are part of a comprehensive program, curriculum matched to the unit 'Introduction to Earth systems'.

This video touches on the following curriculum descriptors:
- Water is present on the surface of Earth as a result of volcanic outgassing and impact by icy bodies from space; water occurs in three phases (solid, liquid, gas) on Earth’s surface (ACSES023)
- Water’s unique properties, including its boiling point, density in solid and liquid phase, surface tension and its ability to act a solvent, and its abundance at the surface of Earth make it an important component of Earth system processes (for example, precipitation, ice sheet formation, evapotranspiration, solution of salts) (ACSES024)
