@NatureLover well you are in luck my friend I lived in America for 14 years and have many many pictures.
The difference between northern and southern hemisphere, if you go in and flush your toilet and watch the water spins clockwise, in the northern hemisphere it spins anti clock wise I think there was a Simpson's episode about it also.
I will find those cloud photos for you and @Emelia8 probably tomorrow, I'm not up for it at the moment, especially after therapy and the colour and it changing.
But ask any questions you want about America and will answer if I can
