GCSE Chemistry - Evolution of the Atmosphere #67

In this video, we'll look at:
- What the early atmosphere was like on earth
- How that atmosphere changed to be suitable for life
- The processes responsible for features of the earth we see today

Hi everyone, to clarify about the percentages not adding to 100% at the start: these percentages are rounded values to make it easier to remember the relative proportions. The true values are closer to 78% nitrogen, 21% oxygen, and 1% for the other gases - though of course you could be even more precise than this, and use more decimal places.

Anybody else’s science teacher make them watch this?

[doorhammer]

the pauses are far far too long, like uncomfortably long

[d_i_a_v_l_o]

this guy has taught me more in a few hours than my chemistry teacher has in 2 years lol

[oghosaIze-iyamu]

My chemistry exam is tomorrow and I can’t thank you enough ❤🙏🏾 I hope I get a high grade in my sciences

[iXeno]

Anyone else annoyed by the pie chart at the beginning adding up to 101% and not 100% >:(

Honestly don't understand how you don't have more viewers, your content is great!
Watched your chemistry playlist before my paper 1 exam on Thursday and I'm hoping it went well, so thank you so much!

[briishtoaster]

who else is here because their science teacher is making them

[infinity]

[stinkylove]

your vids are really carrying my science grades like thank you

[Sam-hnzg]

THANK YOU SO MUCH! I FINALLY found the answer to my earth science question! 🙏

I have an exam today and I was watching as the biology vids on Tuesday and it helped so much. Tysm.

[nakulanil]

This an amazing video thank you so much, I’m gonna get a 9 in biology now.

Got the gcse in less than 12h
Completely fucked

U said the earth used to be dry in the first billion years so where exactly did the water vapour come from

[boopbeepbeepboop]

just a little correction that nitrogen is 78% and oxygen is 21% present in the atmosphere which makes about 1% of other gases like argon.

Great video but do try to add music or something. It was really awkward at times.
Overall good work
