In Why Do We Have Different Seasons?, Isaac Asimov explains how the seasons work and how they affect Earth’s climate, landscape, and various life forms.

There’s little to say about this book. It’s too expensive, but very elaborate and well-illustrated. It’s excellent for young children who want to know a bit about astronomy.

One particular note, however: with the help of a couple of photographs, Asimov is able to explain why the sun is colder when lower in the sky. He spends a largish chunk at the beginning of The Ends of the Earth making the same point, but manages to do so here in far fewer words but just as clearly.
