The biophysical environment
The biophysical environment includes living things (bio), such as plants and animals, and non-living things (physical), such as rocks, soils and water. The biophysical environment is made up of four parts: the atmosphere, hydrosphere, lithosphere and biosphere.
The atmosphere includes gases that are around the earth and everything that happens in them, such as heat from the sun, weather, smog and haze, climate and acid rain.
The hydrosphere is the portion of the earth that is composed of water in all forms – running water, ice and water vapour.
The lithosphere refers to the rocks and soils on the crust of the earth and how our continents form and wear away.
The biosphere is the zone of the earth and adjoining parts of the atmosphere in which plants and animals exist.
Interactions occur between the four spheres.
