In this video, we start by looking at the gases in the atmosphere today and the gases in the early atmosphere. We then look at the processes that took place leading to the current atmosphere.

[@rebrickable123]

I am currently doing higher GCSE separate bio, chem and physics, and have learnt so much from your incredible videos- they are short, to-the-point, inciteful, and brilliant beyond words! I have decided to take Alevel physics next years and am really looking forward to it (thanks so much for inspiring me all throughout physics GCSE) but I am aware you do not offer Alevel videos for physics. Is there another channel you can recommend, similar to yours? Please let me know, and once again, THANK YOU SO MUCH!

In the video sir you said at 1:01 that’ the earth atmosphere is around 4600 million years old’ however on the aqa spec it states 4.6 billion years ago

Hi. 4.6 billion means the same as 4600 million.

So if I remember all the stuff in your vids, is that all I need to know for sciences to get high grade, or do I need to look into more detail about stuff in your vids?

[@oakleygolden-pursey6636]

OriginalLegendz I'm pretty sure u can, it's what I'm doing anyway

[@Mk-hc9jm]

The examboard you are doing might be different as he is doing aqa so its important to use the specification to make sure you are revising everything you need.
Its also important to do as many questions as the new gcses are asking questions where you have to show your understanding and not just give facts

It's the reaction where plants use the energy of light to react carbon dioxide and water, making glucose and oxygen.

hello freesciencelessons love your vid, i just wanted to ask, i was doing a past paper and one of the questions were why are scientists not sure about the early atmosphere what can i put?

[@baldaliv2157]

There is no data because there was no one to record it. They only have a rough estimate because of ice core data.

[@theprowermagic3585]

not enough evidence.

[@zuzannachojecka8736]

What does it mean by algae evolved or plants evolved? Might be a really stupid question but im so confused

[@ShahriyaIsIam]

Zuzanna Chojecka the number of plants increased and/or the different varieties of plants increased

[@Freesciencelessons]

It means that when algae/plants first appeared on Earth by evolution.

[@dhikshithbalaji1714]

hello sir,
your lessons are great, just love them.
Can you please help me with purchasing the workbooks from the store.
which one is the most preferable among the workbooks
with regards,
Dhikshith Balaji

[@Freesciencelessons]

The Triple workbooks cover all the content in the videos for the UK AQA specification. However it does depend on what specification you are following.

[@russellaraujo7058]

Hi sir at 2:56 i am unsure as to how carbon dioxide made shells for sea creatures, could you please explain this. Thanks

[@______6]

Seashells come from organisms that extract calcium and carbon from the water around them to form calcium carbonate shells.

[@studyonly780]

WHY DO PEOPLE NEVER COME BACK W THEIR GRADES??? THEY JUST DISAPPEAR OFF THE FACE OF THE EARTH MAN

[@xaar0n426]

Here an hour before the exam bc I forgot to learn this 💀

[@mercutio4773]

i just want to go to bed

[@hollyscott1878]

How did the mussels dying ands forming limestone remove carbon dioxide from the atmosphere?

[@Freesciencelessons]

They use carbon dioxide to make their shell. When they die, the carbon is trapped in the shell rather than existing as carbon dioxide in the atmosphere.

[@hollyscott1878]

Freesciencelessons thank you, you’re a legend

[@aishahsiddiq1002]

is there a mistake because it says earth was around for 4600 million years but volcanic activity is a billion years?

[@Freesciencelessons]

No it's correct. 1000 million is 1 billion. So the Earth is 4.6 billion years old.

[@katyjohn3089]

Freesciencelessons excuse me sir I would like to ask would it be required to know any other theories about earth atmosphere development or just the volcano activity. Ps really appreciate your vids

[@Freesciencelessons]

Volcanic activity is on the spec so that's the one that you're meant to know. However, they could give you information about a different theory and ask you questions on it to see if you can apply your knowledge.

[@cmoneheudue]

nice vid but i swear earth is 4.6 billion years old not 4.6 million

[@Freesciencelessons]

In the video, I say 4.6 thousand million, which is the same as 4.6 billion.
