Unit 1: Introduction to Earth systems Earth and Environmental Science
The Earth system involves four interacting systems: the geosphere, atmosphere, hydrosphere and biosphere. A change in any one ‘sphere’ can impact others at a range of temporal and spatial scales. In this unit, students build on their existing knowledge …

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, …
