My dear friend, what a journey! From a leaf on the ground to the wonders of the solar system all the way back to the complex world of trees :) How lovely!

Now, I have to call my little nephew and tell him that the reason why the seasons change is because of the earth’s tilt (and not because of its elliptical orbit!). Thanks to one of the sources you shared with us here I will also be able to let him know what has caused our planet to tilt :D

Your engaging discussion about the earth’s obliquity reminded me of some of the headlines that followed Chile’s 2010’s earthquake: That it was so powerful that altered the planet’s axis! ^Ref.. This helped me understand your observation about how the planet’s wobbling influences the seasons as well as the length of our terrestrial days. As it has been said that that the impact of that very earthquake has shortened our days by some milliseconds.

Oh! I find it all so very fascinating :)

Although, if anything, I’d like (need) the days to be longer. And, 2 milliseconds in a hundred years’ time will not do it for me :D

It is incredible how much we can learn by just looking around, asking innocent questions and pursuing them. I guess that’s why I love questions <3

Finally, I couldn’t possibly end my comment without making a remark about your illustrations! So beautiful, it’s a difficult choice, but if I had to pick a favourite one … that would be the falling leaves.

Thank you, my friend from across the sea, for another pleasant, educational read. Gracefully decorated with soothing colours and subtle movements.

With love,
Abigail 😊
