Hass answers 1. Renewable resources are natural resources that can be replenished and are abundant. For example, solar energy or hydropower. 2. Non-renewable are natural resources that cannot be replaced as quickly as they are being used. For example, coal or nuclear energy 3. Continuous resources are natural resources that are not depleted by human use and are available in virtually unlimited quantities. For example, solar energy or wind energy 4. Water is used for: · Irrigation: it is the manual application of water to soil. Its essential for keeping fruits, veggies and grains growing to feed the worlds population. It helps to grow crops, maintain landscapes, and reestablish disturbed soils in dry areas and low rainfall. · Energy production (hydroelectricity): a renewable energy source that uses the kinetic energy of water to generate electricity. It helps provide backup power during major outages or disruptions. It provides flood control, irrigation support, and clean drinking water · Production of other goods (virtual water): the volume of water used to produce consumer products. The total volume of water refers to all of the water used in the production of a product. All products we consume use virtual water. 5. Water cycle: · Evaporation: Water molecules gain energy from the sun and escape into the atmosphere as water vapor. · Condensation: Water vapor cools and turns back into water droplets, forming clouds. · Precipitation: Water falls to the Earth as rain, snow, sleet, or hail. · Infiltration: Water soaks into the ground and becomes groundwater. · Runoff: Water flows across the land and collects in creeks that flow into larger rivers. · Transpiration: Plants release water into the atmosphere through their leaves. · Sublimation: Solid ice and snow turn directly into gas. · Deposition: Water vapor turns into a solid 6. Water is stored as ground water in aquifers. Aquifers are geological formations that store and transmit water. Groundwater is precipitation that has seeped into the soil and collected underground. 7. Causes of water scarcity: · Climate change: Droughts, heat waves, and extreme weather events can impact water supplies. · Population growth: As the population grows, so does the demand for water. · Pollution: Contamination of water sources can make water unsafe to drink. · Poor management: Poor management of water resources can lead to scarcity. · Loss of natural ecosystems: Deforestation and wetland loss can impact water supplies. · Sprawling cities: Urban areas can increase the demand for water. · Agriculture: Water is needed for agriculture, and water shortages can impact agricultural production. 8. What can water scarcity cause? · Water scarcity can limit access to safe water for drinking and hygiene, and can lead to sewage system failure and the spread of disease 9. Ways to overcome water scarcity: · Water conservation: Use less water and use it more efficiently. This can include taking shorter showers, installing low-flow toilets, and using high-efficiency clothes washers. · Improving irrigation efficiency: Switch from flood irrigation to sprinklers or drip systems to save water. · Recycling water: Treat water that has been used for one purpose and reuse it for a different purpose. Industrial facilities can recycle cooling water, process water, and rinse water. 10. Ways to reduce use of water: · Short showers · Fix leaks · Install water efficient taps + showerheads · Turn off taps · Don’t pre-rinse dishes · Repurpose water · Use a dishwasher 11. Other methods of supplying water: · Recycling water: treated wastewater that can be used for a variety of purposes. WA is hoping to recycle 35% of wastewater by 2025 · Desalination: a water treatment process that removes salts and minerals from water to make it suitable for human consumption, irrigation, or industrial use. It’s used commonly to supply communities that have difficulty accessing freshwater. It's one of the most common ways to obtain fresh water for human consumption and agriculture
