Science The Earth's Resources-Lesson 4
| Question | Answer |
|---|---|
| what is air pollution | the addition of any unwanted substance into the air |
| what is a pollutant | the unwanted substance in air |
| what causes a great deal of air pollution | people |
| how does air pollution come from natural causes | when lightning strikes a tree and starts a fire in the forest the smoke and ash from the fire can pollute the air |
| how does a volcano cause air pollution | when it erupts and shoots dust, gas and ashes into the air |
| how can wind pollute the air | by picking up large amounts of dust from the ground and blowing it through the air |
| what is the difference between the air pollution today compared to a few hundred years ago | the air pollution a few year ago was caused mostly by natural resources today it is caused by people |
| what are some ways people cause air pollution | cars, power plants,wood-burning stoves,trash burners and factories |
| what happens when something is burned | pollutants are released |
| what gases are air pollutants | carbon monoxide and carbon dioxide |
| what gases are produced when fuel burns | carbon dioxide and carbon monoxide may be produced |
| carbon monoxide | a colorless, odorless and poisonous gas |
| what is Ozone | a molecule with three atoms of oxygen instead of just two that an oxygen molecule usually has |
| what is Ozone in a lower atmosphere | it is a pollutant that may make it hard for some people to breath |
| what causes the ozone gas in the atmosphere | a reaction between some pollutants and sunlight in the atmosphere |
| how can dust be a pollutant | when people drive on dirt roads or gravel or farmers plow their fields the dust enters the air |
| where do the chemicals that evaporate into and pollute the air come from | paints, cleaning products,hair sprays,and glues |
| what can happen if you breath pollutant air | you can have health problems |
| what happens if you breath small amounts of carbon monoxide | it can be hard for your body to get enough oxygen, tiny amounts can cause headaches and dizziness |
| what can ozone irritate | the lungs |
| what can some pollutants do to your eyes | irritate the eyes and the membrane around them |
| what can inhaling high levels of pollutants do | it can cause coughing, and make it difficult to breath and cause asthma to worsen |
| what can get trapped in the lungs | dust and particles from burning fuel |
| what happens over time to the lungs that breath in and trap particles | lung damage |
| how can they limit exposure to heavy pollutant days | post signs to stay indoors on those days |
| how is acid formed from pollutants | when pollutants in the air react with water vapor a acids form |
| what is acid rain | rain containing the acids formed from pollutants reacting with water vapor |
| why is acid rain bad | because rain or snow with these acids can injure or kill organisms, it can kill organisms in lakes |
| what non-living things can pollution harm | it damages buildings, monuments, especially those made of marble and limestone, rubber and plastic material |
| what do scientis believe can damage farmers crops | acid rain and ozone |
| what types of living things are harmed by pollution | animals,plants and other organisms |
| what do scientist believe about increased amounts of carbon dioxide and other gases do to the earth and its atmosphere | it may causing the atmosphere to get warmer which can cause the climate to change and it could be destroying the ozone that is high in the atmosphere |
| what does the ozone high in the atmosphere protects us from | the sun's harmful ultraviolet rays |
| what can happen with less protective high in the atomosphere ozone | skin cancer could become more common |
| how can you help reduce air pollution from motor vehicles | ride bikes, walk and take the school bus so there are less cars being used |
| how does conserving energy reduce air pollution | if you conserve the use of electricity you reduce how much electricity the power plants have to produce and this reduces how much air pollution the power plant makes to produce the electricity |
| what are the three R words to help conserve energy | reduce, reuse, and recycle |
| how can you reduce the number of things factories produce | buy less new things, reuse and take care of old things |
| what does recycling do | reduces the amount of trash that must be burned or hauled by trucks to landfills, which reduces pollution from the burned trash and reduces pollution by trucks |
| what is the difference between old cars and new cars with regard to pollution | newer cars produce 95% less pollution than cars made 30 years ago, todays cars are fuel-efficient and pollute less |
| how are industries working to reduce air pollution | some find way to reduce the amount of energy they use, and some change how they make things |
