please use this thread to teach verifiable laws of nature...
What happens is that, in some rare cases, an animal or leaf -- or even an entire forest -- is covered by a layer of mud or earth or sand that over long geological aeons is compressed by earth forces to become shale or sandstone, with the animal or plant still encased. The cells of wood and bone are replaced by minerals -- and they become stone -- replicating the cellular structure exactly.How is it, in the case of fossils, that the dead animal completely disintegrates (bones etc.) but the dirt it left the impression in keeps the shape and becomes completely solid. Wouldn't it make more sense since the dirt I assume is wet when it takes the imprint that since the carcass is more solid initially, the the dirt would lose the shape and the carcass remains intact then the other way around?
Thanks. Do you speak Arabic?Thank you for your answer.
I'll have to re-read it a few times to make sure I understand it fully.
God be with you (or Allah ma'ak as we say in 'arabic).
Why is the sky blue?Why does the o-zone layer appear to be blue from the ground but is transparent from above?
An aeroplane flies at a set altitude above the ground. Aircraft have to apply for permission to fly and log their routes in advance, so that air traffic control can avoid accidents. An aeroplane is really very tiny compared to the size of the earth. Imagine an ant on a big hot-air balloon -- the canvas looks flat to the ant, until it's high enough above the surface of the balloon to see the curvature.Assuming the earth is a globe, why do planes flying straight not gradually get higher and higher off of the ground?
You talked about many things but not gravity.An aeroplane flies are a lot of aeroplanes.
Sir Isaac Newton's famous for his basic formula calculating gravity! It's taught in Physics iirc...You talked about many things but not gravity.![]()
Is gravity needed to answer the question?You talked about many things but not gravity.![]()
IMHO, it is essential for @abuyusufalshafii's question. To compensate gravity, the ailerons give the upthrust.Is gravity needed to answer the question?
It's the same reason that the moon "shines" at certain times; they're reflecting our sun back at us. If we left Earth for the moon or any other planet/moon, the same phenomenon would occur..Thank you for all your replies, I have one last question for now, after which I will review all the responses and this one always confused me:
The things we call planets, from the ground look just like stars and how is it that they appear as light from the ground, yet the closer you get to them the darker and colder they get when sources of light. as we know get lighter and hotter from up close? (referring to Saturn, Venus, Jupiter etc.).
Yes, and thank you.Am I making sense?![]()
