| Question | Answer |
| Describe the water cycle (key words) | Evaporation/Transpiration, condensation, precipitation |
| What changes can water have? | Fusion or solidification, condensation or vaporisation, inverse sublimation or sublimation. |
| In what ways do we use water? | Consumptive, non-consumptive |
| What is a consumptive use of water? Give examples. | Water doesn't return to water cycle. Industrial, domestic, agriculture and livestock. |
| Why is sustainable management important? | Because water is an essential resource that is constantly threatened by pollution. |
| What percentage of water can we need for agricultural use? | We use the 79 percent of the water. Example: For 1kg of potatoes we need 500 l of water. |
| What examples of domestic use do we need a lot of water for? | Examples: Washing the car 300 l Filling the bath 200 l |
| In industrial use, do we spend a lot of water in Spain? | No, comparing with the others uses. |
| If you want to save water, will you have a shower or a bath? | I'll have a shower because if I use the bath I am going to spend more water. |
| What is the non-consumptive use of water? | When the water we use is returned to the water circle without a significant alteration in its quality. |
| Give examples of non-consumptive things. | Recreation activities (pools, water parks...), transport and production of hydroelectric power. |
| What should the sustainable management implement? | Ways to guarantee responsible use and ensure availability for future generation. |
| What can you do not to spend a lot of water? | For example having quick showers. |
| What is water pollution? | It's the alteration in the composition of water that makes it inadequate for its intended use. |
| What are the factors considered to measure the quality of water? | The temperature, the quantity of dissolved oxygen, the presence of certain microorganisms, the colour, the flavour and the odour. |
| What are the main sources of water pollution? | a) Domestic pollution and Industrial pollution. b) Wastewater and algae. c) Pollution from agriculture, livestock farming, domestic pollution and industrial pollution. |
| What are the zones according to its water quality? | Clean zone, polluted zone and self-purification zone. |
| What is wastewater? | Water polluted by domestic use. |
| Can the water used in industries kill species? | Yes |
| What are the main effects of water pollution? | 1. Death of aquatic (water) animals. 2. Disruption of food-chains. 3. Diseases. 4. Destruction of ecosystems. 5. Rising levels of mercury in oceans. |
| Why is mercury dangerous for children and pregnant women? | a. Because it affects the development of the central nervous system. b. Because it affects the development of the digestive system. c. Because it affects the development of the bones. |
| Water-borne diseases are those communicated by water, especially by drinking water. | Yes |
| Water-borne (transmitted by water) diseases can be: | a. cholera and tuberculosis. b. rabbies and flu. c. AIDS |
| Water pollution can also significantly increase the rate of algal blooms, which create massive fish die-offs as the oxygen in the water gets depleted and the fish suffocate. | Yes |
| How can we prevent water pollution? | 1. Put rubbish in the correct bin. 2. Use water wisely. 3. Don't throw chemicals to the toilet. 4. Don't throw used oil down the sink drain. 5. Buy “green” (environmentally safe) cleaning liquids. 6. Do not to overuse pesticides and fertilizers. |
| Which target are water laws directed to? | They are usually directed at industries, hospitals, schools and market areas. |
| What does law focus on about water pollution? | On how to dispose, treat and manage sewage. |
| In Spain, is waste or sewage treatment very efficient? | Yes. |
| Who is in charge of water treatment in Pamplona? | a. La Mancomunidad de la Comarca de Pamplona. b. The townhall. c. The Government of Navarra. |
| There is a new system of water sanitation and purification in Arteta (Ollo Valley). | Yes |
| Who is in charge of controlling the quality of the water we drink in Spain? | SINAC (Sistema de Información Nacional de Aguas de Consumo) |
| Farmers in Navarre who want to contribute nutrients to the soil can ask for sludge (mud) from the Arazuri WWTP (Water waste treatment plant). | Yes |
| The first water supply to Pamplona took place in 1790, from the fountain of Subiza. | Yes |
| What are the properties of pure water? | Colourless, odourless, tasteless |
| What changes can water suffer depending on the temperature? | Fusion or solidification, condensation or vaporisation, inverse sublimation or sublimation |
| The melting point of the water is... | a) 0 ºC b) 100 ºC c) -17,15 ºC |
| The boiling point of the water is... | a) 500 ºC b)100 ºC c) 0 ºC |
| Is solid water more dense than liquid water? | No |
| Why that is good for our life? | If solid water was more dense than liquid, lakes would totally freeze and fish,frogs... would die. |
