Oak trees need nitrogen or carbon dioxide to live but because they don’t need oxygen the tree will release it to the world for the human to breathe
I’m not too sure what geoscience is, is it like earth science or..? Anyways I took chemistry online this year and I think it’s ok to say I would have rather taken it in person, just because chemistry can sometimes be confusing -at least for me, and I’m generally a smart person oof. Ik my answer may be biased because i took earth science in middle school and chemistry now (10th grade), but I would say take chemistry. If you take chemistry now then a LOT of things will make sense and if you do geoscience in 11th grade or smth it may be a lot easier to understand.
They are called Zircons, they date back to almost 4.4 billion years ago. Hope this helps, please give me the brainiest, thanks.
