WEEK 3: Up, Up and Away
DAY 5: Here to Stay
Activity 1: Persistent Pollution [4 points]
In 2016, the World Health Organisation announced that Timaru, a small town in the South Island of New Zealand, had the highest recorded levels of air pollution in New Zealand. Some of this pollution was caused by natural events (eg. fires) but most of it was produced (made) by humans.
Watch this short video on air pollution. It will tell you more about the natural and human causes of pollution.
On your blog, share three new things that you learned about air pollution from this video.
Air Pollution
- Smog: a type of air pollution that reduces visibility and has serious health effects.
- Sulfurous Smog: also called London Smog is made out of chemical compounds called sulfur oxides and is caused by the use of sulfur-bearing fossil fuels, particularly coal.
- Photochemical Smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds react to sunlight, creating a brown haze above the cities. It tends to occur more often in summer, where we have the most sunlight.
Hi Lyan,
ReplyDeleteGosh there are some complicated words and phrases you have used there! Do you understand them all? I found it a little hard to understand!
My husband comes from Timaru so I have visited there quite a few times. There certainly is pretty bad smog there at times, particularly in winter when a lot of people have fires going to keep warm.
One thing I learned when I was researching this was that the word 'smog' is made up of 'smoke' and 'fog'!
Thanks for sharing your learning on your blog.
