About the book

Uses a question and answer format, with illustrations, to explain why the sky is blue, what a rainbow is, what atoms are, how gravity works, and many other scientific facts and events.

First sentence: When Earth is on one side of its orbit, the northern hemisphere is tipped toward the sun, so radiation hits more squarely, during about 15 hours of daylight per day-causing summer in the northern hemisphere and winter in the southern hemisphere.
