| for long time , the earths early atmosphere was mostly co2. where did it come from? | volcanoes
🗑

| what 3 mains gases is the current atmosphere made of? | nitrogen - 78%
oxygen - 21%
argon - 1%
🗑
|
||||
| name one way that pollution can cause direct harm to humans? | they can cause disease and even death to people who breath it in to much
🗑
|
||||
| name one way that pollution can cause indirect harm to humans? | by damaging the environment like acid rain.
🗑
|

| what is a hydrocarbon? | hydrogen and carbon atoms ONLY
🗑
|
||||
| name the main element that makes up coal? | carbon
🗑
|
||||
| when a hydrocarbon burns, with what substance do the hydrogen and carbon atoms combine? | hydrogen combines with oxygen to make h2o or water and the carbon join up with oxygen to make co2
🗑
|
||||
| when hydrocarbons burn in plenty of oxygen, the atoms involved rearrange themselves into carbon dioxide and what else? | h2o
🗑
|
||||
| what removes carbon dioxide from the atmosphere? | plants remove co2 from the air through the process of photosynthesis
🗑
|
||||
| what atoms make up carbon monoxide? | 1C and 1O only on atom of each
🗑
|
||||
| when does burning release carbon monoxide? | when it is incomplete
🗑
|
||||
| what particles of carbon otherwise known as? | particulate carbon
🗑
|
||||
| describe briefly how sulfur dioxide is produced? | sulfur comes from impurities in fuels
fossil fuels contain lots of impurities, so when they are burned so is the sulfur, the sulfur then joins up with the oxygen to make sulfur dioxide
🗑
|
||||
| give the formulas of nitrogen monoxide and nitrogen dioxide? | NO - nitrogen monoxide
NO2 - nitrogen dioxide
🗑
|
||||
| what effects does acid rain have on the environment | it cause lakes to become acidic, killing plants and animals.it also kills trees and damages some stone buildings and statues
🗑
|
||||
| what do catalytic converters do? | they convert harmful nitrogen monoxide into harmless nitrogen and oxygen, they also convert carbon monoxide into carbon dioxide by adding oxygen
🗑
|
||||
| name 2 things that everyone could do in order to reduce carbon dioxide pollution | you could car share or take public transport, this means you can get more people on one trip rather than having smaller groups in lots of cars
🗑
|
||||
| how do MOT tests help reduce air pollution | there is a legal limit on how much pollution your car can produce, this means that only the cars that are clean enough will be allowed.
