On July 26, 1943, Los Angeles was blanketed by a thick gas that stung people’s eyes and blocked out the Sun. Panicked residents believed their city had been attacked using chemical warfare. But the cloud wasn’t an act of war. It was smog. So what is this thick gray haze actually made of? And why does it affect some cities and not others? Kim Preshoff details the science behind smog.
Lesson by Kim Preshoff, directed by Juan M. Urbina Studios.

Very good video! Thank you Kim Preshoff for sharing this with us :)
I live in Santiago de Chile, a city historically affected by smog. The city lies in a valley, which makes the problem worse. In the last years, luckily, the cases of extreme pollution have dropped significantly thanks to state policies, but there is still a lot to do.
The most complex of events and terms explained in the simplest words!! Thanks Ted-ed and all other lecturers like Mam Kim Preshoff!!
Thank you Kim!
Way to go Kim!!!
thanks Kim for giving your precious time to us, and teaching us

Wishing you more recognition and acknowledgement all the way from India❤️

The way she pronounced Glasgow.
is incredibly irritating
ahahahha glosgaow
Khushil Parikh you pronounce the "o" in Glasgow.
I came looking for this comment
Khushil Parikh, it's Glas-go (at least in British English, not sure about American English)
IF U CAN I HAVE ANOTHR IDEA FOR A VID:
1) HOW DOES POLYMERISATION OCCURE
2) HOW TO REDUCE POLLUTION
I watched all her videos and all of them are so good. Thanks Kim
Nice stuff Kim and the whole Ted-ED team :). Always glad when I see that you have uploaded a new video
What I learned today:
TED-Ed help amplify the lessons of great teachers

Great job Kim! Well explained, concise, and beautiful graphics! 👍
Nice job, Mrs. Preshoff! Thank you for the clear exposition!
Hi, generally a good video. However, nitrous oxide (N2O) is not the same as nitric oxide, also know as nitrogen dioxide (NO2 or N2O4 since it exists as a dimer), which is what the real problem is in smog. This is often represented as NOx. These are very different compounds with completely different properties. They are as different as water and hydrogen peroxide. Nitrous oxide, is a colorless, nontoxic gas, in fact it is used as a dental anesthetic. N2O4 is a reddish gas which is highly reactive, corrosive, and toxic. It would also be reasonable to refer to the compounds in smog as "nitrogen oxides", if you prefer. Please correct this.
Nice Kim
Wow! Thank you Mrs. Preshoff! Hope to see more of her very soon!
Thank you Mrs. Preshoff for your wonderful contributions.
0:57 sounded like the beep in among us
Lmaoo it does
💟💖Kim Preshoff💕🎀
Thanks for educating us kim!
Congratulations Kim - Very good insightful lecture. First of your videos I saw. Will watch all of them. 👍
Loved the way she pronounced Glasgow
UniVoidz
This is the first comment in wich a person is happy for the way she pronounced that word. (😂😂😂)
I also liked the way she said that word!
UniVoidz it's just a shame it and Edinburgh were pronounced completely the wrong way.
Koffing, use smog attack!
From Pokémon!
It was a lovely presentation Mrs. Preshoff!
well done Kim, & thanks for the video.
There's like 4 first comments.
I'm early let me make a joke
USA
Firstly, thank you Kim. Delighted to know such teachers are still there😊. Secondly, thank you Ted Ed for supporting such initiatives, and making the learnings of these teachers available to us. Thirdly, amazing animation, as always.
Congratulations Kim! It's always great to see great videos being made by amazing people like you!
*SMAUG* ... anyone get it?
the desolation of smog ? NO I don't get it
1:21 who also thought it was a cow at first? xD
umm it's a cow
But, it IS a cow
Oh, nvm, it's a bull because it has horns, but it's also genderless, because it has udders and horns
cows do have horns
He meant who thought that it was the cow which causes the mentioned kind of pollution.
Mrs Preshoff, your lessons are definitely worthwhile! Keep up the great work!
Ms Kim! Great stuff, always loved science.
EARLY HURRRAYYYY
Incredible chanel☺.If you agree with me, give a thumbs up.
Keep up the awesome work Kim!
Thanks a lot Kim! I was just was watching the crown and it talked a bit about the smog of 1954 in London. You explained it so well! Keep up the good work!
I am slightly annoyed at the way she pronounced Edinburgh and Glasgow it's Pronounced (Glas-Goh) and Edinburgh is pronounced (Edin-Bruh) not that difficult. Never even heard them be pronounced that way before.
mhmm i'm from edin and omggg
you Scots are so annoying
What was that pronunciation of Glasgow? It's pronounced Glasgo
omg yeah glosgaow and like i love in edinburgh and it's noT edinboro
brendon urine She pronounced Edinburgh like I would. I'm from Stirling
brendon urine
but how is it pronounced then? Our english teacher also pronounces it that way.
Sugar Cat Glaz-go and Edin-bra or Edin-bruh
Rebecca Erin Connolly Edinburuh not Edinbruh
Thank you for the educational video Kim!
A big thank you to Mrs. Preshoff and TED-ED team for such wonderful resources.
