water in the world
| Question | Answer |
|---|---|
| What are the main types of water on Earth? | Saltwater (about 97%) and freshwater (about 3%). |
| Where is most of Earth’s freshwater stored? | In glaciers, ice caps, and underground aquifers. |
| What does the term spatial distribution of water resources mean? | How water is spread or located across different parts of the world. |
| Why does the distribution of water vary globally? | Due to factors like climate, rainfall, geography, and human access to infrastructure. |
| Name three main forms of water used as resources. | Surface water (rivers, lakes), groundwater, and rainwater. |
| What are the main processes of the water cycle? | Evaporation, condensation, precipitation, infiltration, runoff, and transpiration. |
| How does the water cycle connect people and places? | Through shared water systems like rivers, rainfall, and catchments that cross regions. |
| What factors influence water flows and availability? | Latitude, altitude, topography, location, and climate change. |
| What is a catchment area? | The area of land where all water drains into a single river or body of water. |
| What are the main sources of freshwater in Australia? | Rivers, groundwater, dams, and rainfall. |
| Why do water resources vary across Australia? | Because rainfall and climate differ greatly between regions (north = wet, interior = dry). |
| Which parts of Australia have the most water? | Northern and eastern regions (tropical and coastal zones). |
| What are the two biggest rivers in Australia? | The Murray and Darling Rivers. |
| How does Australia’s water availability compare with other continents? | Australia is the driest inhabited continent, with highly variable rainfall. |
| What is water scarcity? | When water demand exceeds the available supply. |
| What are the two main types of water scarcity? | Physical scarcity (not enough natural water) and economic scarcity (lack of access or infrastructure) |
| What causes water scarcity? | Drought, overuse, pollution, population growth, and climate change. |
| How can governments manage water sustainably? | By building efficient water systems, regulating use, recycling water, and protecting catchments. |
| What can individuals do to manage water sustainably? | Use less water, fix leaks, install water-saving devices, and reuse greywater. |
| What role do NGOs play in water management? | They promote clean water access, build wells, and educate communities globally. |
| What are the four main values of water? | Economic, cultural, spiritual, and aesthetic. |
| Give examples of water’s economic uses. | Agriculture, industry, energy production, and trade. |
| What is an example of water’s cultural or spiritual value? | Aboriginal and Torres Strait Islander Peoples see water as sacred and essential to Country. |
| How do people’s perceptions of water vary? | Some value it for profit (economic) while others value its beauty or spiritual importance (aesthetic/spiritual). |
| Compare the importance of water to one Aboriginal community and one Asian community. | Both depend on water for culture, agriculture, and spirituality, though specific customs and uses differ. |
| What is a hydrologic hazard? | A hazard related to water, such as floods or tsunamis. |
| What is an atmospheric hazard? | A weather-related hazard like cyclones, storms, or droughts. |
| What causes floods? | Heavy rainfall, overflowing rivers, or blocked drainage. |
| What are the impacts of floods? | Damage to homes, crops, infrastructure, and sometimes loss of life. |
| How can people and governments reduce the impact of natural hazards? | By planning evacuation routes, building levees, and improving warning systems. |
| How might climate change affect hazards? | It can increase their frequency, severity, and unpredictability. |
| What are latitude and longitude used for? | To find exact locations on Earth. |
| What is direction? | The way something moves or is located, shown with compass points (N, S, E, W). |
| What is scale on a map? | The ratio between map distance and real distance (e.g., 1 cm = 1 km). |
| What do contour lines show? | Elevation and the shape of the land — close lines mean steep slopes. |
| What is a synoptic chart? | A weather map showing air pressure, wind, and rainfall. |
| What do climate graphs show? | Monthly temperature (line) and rainfall (bars). |
| What are area references? | 4-digit map coordinates locating a general area (e.g., AR 3421). |
| What are grid references? | 6-digit map coordinates locating a specific point (e.g., GR 342156). |
