|---|
| Aquifiers | A rock formation containing water, especially one that supplies the water for wells, springs |
| Artesian Basin | Groundwater confined and pressurised within an aquifier |
| Catchment | Area of land where precipitation flows to a lower elevation, such as a river, lake or ocean |
| Climate | Long-term record of atmospheric conditions such as precipitation and temperature |
| Climate Change | Changes in the world's climate due to natural and human activities |
| Continuous Resources | Resources always available (sun, wind, tides) |
| Convection Precipitation | Occurs when evaporation over heated land surfaces causes moist air to rise |
| Environmental Resources | Resources occurring naturally within environments: atmosphere (air), lithosphere (land, soil and minerals), hydrosphere (rivers and oceans), biosphere (plants and animals) |
| Groundwater | Water stored beneath the earth's surface |
| Infiltration | Process whereby surface water seeps underground to become groundwater that then may flow into streams, rivers, lakes, seas or artesian basins |
| Non-renewable resources | Resources formed slowly - often over millions of years - and once used cannot be replenished in the short term |
| Precipitation | Process whereby the suspended droplets in the atmosphere fall as rain, hail, sleet or snow |
| Salinity | Quantity of salt in the soil, land and air affecting biodiversity, agricultural productivity and buildings |
| Sustainability | Balancing social, economic and environmental needs for current and future generations |
| Synoptic Chart | Weather map |
| Water Cycle | Continuous movement of water on earth |
| Water Table | Uppermost groundwater |
| Weather | Short-term changes in atmospheric conditions |
| Arid | having little or no rain; too dry or barren to support vegetation |
| Semi-Arid | a climate or place that is partially arid, or semi-dry and has less than 20 inches of rain each year. An example of semiarid climates is the hot, semiarid climate of the Outback in Australia |
